Metal sheet handling in modern fabrication demands equipment that balances three competing requirements: load capacity for heavy plates, surface protection for quality-critical materials, and cycle speed for production throughput. Magnetic lifters sacrifice material versatility for grip strength. Chain slings sacrifice surface quality for simplicity. Robotic loaders sacrifice cost-effectiveness for automation. The Herochu pneumatic vacuum manipulator for metal sheets integrates all three requirements in a column-mounted system that handles 300 to 500 kg sheets through vacuum grip, pneumatic balance, and multi-axis positioning. This class of equipment also serves as a pneumatic manipulator for sheet metal crane material lifter applications, combining crane-level reach with vacuum-based plate handling.

Operating Principle: Vacuum Grip Meets Pneumatic Balance

The Herochu HC-RP series manipulator combines two independent pneumatic systems in one machine. The first system generates vacuum at the suction cups — compressed air passes through ejector nozzles that create negative pressure at the cup face, pulling the sheet against the polyurethane lip to form a seal. The second system balances the load weight — air pressure in a cylinder counterbalances the combined mass of the sheet and the boom assembly, allowing the operator to move the load with minimal force.

These two systems work in sequence during every handling cycle. The operator positions the vacuum frame over the sheet, opens the vacuum valve to grip, then moves the sheet through the working area using the balanced boom. At the destination, the operator lowers the sheet to the surface and releases the vacuum valve. The entire sequence takes seconds, and the operator’s physical effort is limited to directional guidance — the pneumatic system carries the weight, and the vacuum system maintains the grip.

This separation of functions matters because it allows each system to be sized independently. A shop handling thin, wide sheets needs maximum vacuum cup coverage but low load capacity. A shop handling thick, heavy plates needs high load balance but can use fewer cups. The Herochu eight-cup, 200 mm diameter configuration serves both extremes because it provides the coverage for thin sheets and the distributed grip strength for heavy plates.

The Eight-Cup Vacuum Array in Practice

Eight vacuum cups arranged across the boom frame provide operational advantages that go beyond simple load distribution. Each cup acts as an independent grip point — if one cup contacts a warped sheet edge, a cut remnant, or a surface irregularity and fails to seal, the remaining seven cups still hold the sheet securely. This redundancy is critical when handling cut parts and remnants that do not present a flat, continuous surface to the cup array.

The 200 mm cup diameter is sized for the contact area needed to maintain vacuum on slightly imperfect surfaces. Smaller cups concentrate force and lose seal easily on warped or oily plates. Larger cups consume boom space and reduce the number that fit on the frame. The 200 mm specification, multiplied across eight cups, provides a total grip area that sustains the full 500 kg load with safety margin.

Cup material is polyurethane, selected for its resistance to the contaminants present on metal sheets — cutting fluid, drawing oil, mill scale dust, and surface rust. The cups flex to conform to slightly curved or warped sheet surfaces, maintaining seal contact where a rigid cup would leak. When cups eventually wear, replacement is a bolt-on procedure that does not require disassembling the vacuum circuit.

Rotation and Reach Geometry

The manipulator’s 220-degree rotation angle defines the working area it can serve from a single column position. Placed at the junction between a storage rack and a machine table, the boom sweeps from the rack position through the full arc to the machine position. The operator does not need to reposition the column or extend the boom to reach different points — rotation alone covers the working area.

The 3600 mm boom length determines how far the boom reaches from the column centerline. At full extension, the vacuum cup frame sits 3600 mm from the column, allowing the manipulator to reach into the center of a 4000 x 2000 mm sheet rack or to place a sheet at the back of a large cutting bed. The 700 mm lifting stroke moves the sheet vertically between rack height and machine table height, accommodating the elevation difference between horizontal storage and processing surfaces.

The 3600 mm column height provides the vertical clearance needed to lift sheets above storage rack sides and machine table edges during the swing from rack to machine. This height also accommodates tall sheet stacks in storage — the operator lifts from the top of the stack without needing to position the boom below the rack top, which would require a different boom approach angle.

Material Range and Application Scope

The Herochu pneumatic vacuum manipulator for metal sheets handles three primary material types without configuration changes: carbon steel, stainless steel, and aluminum. Each material presents different handling characteristics that the vacuum system accommodates automatically.

Carbon steel sheets carry mill scale — the oxide layer formed during hot rolling. This slightly rough surface provides good vacuum seal texture. The cups grip carbon steel reliably across the full thickness range from 1 to 20 mm.

Stainless steel has a smoother, more consistent surface. Vacuum seals form quickly and hold firmly. Stainless sheets are often polished or brushed for visible applications, making the non-marring polyurethane cups essential — any contact mark from a chain or magnet would require rework.

Aluminum sheets are lighter per unit area but larger in format. The oxide layer on aluminum does not interfere with vacuum adhesion. Aluminum’s softer surface is vulnerable to denting from edge contact with chains or forks, but the flat, distributed contact of vacuum cups eliminates this risk.

Beyond metalworking, the manipulator handles plastic sheets within the same weight and size envelope, extending its utility to fabrication shops that process mixed material types on shared equipment.

Control Options: Manual and Automatic Operation

The Herochu manipulator offers both automatic and manual control modes to match different production environments. Manual control gives the operator direct command over vacuum engagement, boom movement, and sheet positioning through hand-operated valves and guided boom motion. This mode suits high-mix production where sheet sizes, materials, and destination positions change with every cycle — the operator adapts in real time without programming.

Automatic control integrates sequence operations for repetitive loading patterns. When a shop runs the same sheet size to the same machine position for extended production runs, the manipulator can execute the grip-swing-place-release cycle with reduced operator input, improving consistency and reducing fatigue across long shifts.

Both control modes operate through the same pneumatic and vacuum systems — the difference is in the control interface, not the lifting mechanics. Shops can start in manual mode and transition to automatic operation as production patterns stabilize, without modifying the manipulator hardware.

Safety Systems for Protected Operation

The emergency air-cut protection system defines the manipulator’s safety architecture. If air supply fails during a loaded cycle, the vacuum holding valve seals immediately, and the sheet remains gripped. The boom balance cylinder also locks, preventing uncontrolled descent. The operator can then guide the load down manually at a controlled rate. This fail-safe design ensures that a utility failure — compressor outage, hose failure, or air pressure drop — never results in a dropped load.

The anti-collision device adds physical protection against operator error. Contact between the boom or frame and an obstruction triggers an immediate stop, preventing the sheet from being driven into a machine edge, rack component, or adjacent structure. Together, these systems allow sustained operation at production pace without the elevated risk that heavy-load handling normally entails.

As a heavy steel plate lifting beam supplier, Herochu engineers the boom assembly to function as a rigid lifting beam that carries plate loads across its full reach while the vacuum cups maintain flat, distributed grip — combining beam structural capacity with vacuum holding power in one integrated system.

In sheet metal fabrication, the transition from storage to processing defines cycle time and throughput. Material that sits in a rack must reach the cutting bed, the press brake, or the welding station quickly, safely, and without surface damage. Traditional cranes handle the weight but introduce swing, chain marks, and operator dependency. The Herochu sheet metal crane material lifter redefines this transition by combining crane-class load capacity with pneumatic balance control and vacuum grip technology, creating a handling system that moves metal plates through space with operator-directed precision.

Defining the Sheet Metal Crane Material Lifter Category

A sheet metal crane material lifter occupies a functional space between overhead bridge cranes and dedicated automated loading systems. It provides crane-level lifting capacity — up to 500 kg per sheet — but mounts on a fixed column and boom rather than running on overhead rails. This mounting method delivers specific advantages for fabrication shops with limited bay height or existing overhead crane infrastructure that cannot be dedicated to a single loading point.

The Herochu HC-RP series fits this category precisely. The 3600 mm column provides the height needed to clear machine tables and storage rack tops. The 3600 mm boom sweeps the 220-degree arc from rack to machine. The vacuum cup frame at the boom end grips the sheet directly, replacing chains, slings, and magnets with a non-marring contact method that preserves sheet surface quality.

Unlike a full gantry loading system, which requires floor-mounted rails, programmable motion control, and significant installation engineering, the column-mounted pneumatic lifter bolts to a single foundation pad and operates immediately after air and anchor connections are complete. This makes it practical for shops that need lifting capability without a capital project timeline.

Lifting Mechanics and Position Control

The defining characteristic of the Herochu crane material lifter is its position control. A standard crane swings a load on a pendulum — the operator manages both the horizontal motion and the resulting swing, requiring constant correction. The pneumatic manipulator eliminates pendulum effect entirely. The boom moves the sheet through a rigid arc, and the pneumatic balance cylinder holds the load at any elevation within the 700 mm lifting stroke without drift.

This stop-and-hold capability changes how operators approach sheet placement. When loading a laser cutting machine, the operator picks the sheet from the rack, swings it to the machine, lowers it to table height, and releases. At each step, the manipulator holds position without additional input. The operator can pause mid-motion to adjust the approach angle, check for obstacles, or reposition their stance — the sheet stays where it was left. No pendulum correction, no brake engagement, no drift.

The 220-degree rotation further extends placement control. The boom rotates the sheet around the column axis, and the vacuum frame rotates the sheet relative to the boom. This dual-axis rotation means a sheet stored flat in a rack can be picked, turned to any orientation, and placed flat on a machine table — all in one continuous motion without setting the sheet down between orientation changes.

Vacuum Grip Technology for Surface Protection

The lifting method matters as much as the lifting mechanics. Chains scratch. Magnets leave marks on thin sheets and fail on non-magnetic materials like aluminum and stainless steel. Forklift forks bend thin-gauge plates. The Herochu vacuum suction cup system avoids all of these failure modes.

Eight cups, each 200 mm in diameter, contact the sheet surface and pull vacuum through pneumatic ejectors. The cups grip the sheet across a wide contact area — not at two edge points like a chain sling, or along one line like a fork. This distributed grip prevents the bending and flexing that thin sheets undergo when lifted from edge points only. A 1 mm thick sheet picked by eight vacuum cups stays flat during transport, while the same sheet lifted by chains would bow and potentially deform permanently.

The non-marring nature of polyurethane cups means polished stainless sheets, painted panels, and pre-finished materials can be handled without surface preparation or post-handling cleanup. For shops fabricating visible-surface products — appliance panels, architectural metalwork, food-grade equipment — this surface protection carries direct economic value in reduced rework and scrap.

Model Selection and Application Mapping

Herochu configures the crane material lifter in two primary models to address different sheet sizes and weights. The HC-RP3015-300 handles sheets to 3000 x 1500 mm at 300 kg maximum. This model serves shops whose cutting beds and material inventory center on standard 3 x 1.5 meter sheets in gauges from 1 to 8 mm. The 300 kg capacity covers the full weight range of these sheets in carbon steel.

The HC-RP4020-500 extends to 4000 x 2000 mm sheets at 500 kg. Shops using larger format material — typically for heavy equipment fabrication, structural work, or thick plate processing — select this tier. The 500 kg capacity handles 20 mm thick carbon steel plate at the maximum sheet dimensions without approaching the structural limit of the boom or column.

Both models support the same material range: carbon steel, stainless steel, and aluminum. The vacuum system does not require material-specific configuration — the cups grip each material type with equal reliability, and the operator does not adjust vacuum pressure or cup arrangement between material changes.

Floor Integration and Installation Requirements

Installation of the Herochu crane material lifter requires a concrete foundation pad capable of supporting the column base plate and the moment loads generated during full-capacity boom extension. The pad dimensions depend on soil conditions and concrete thickness — Herochu provides foundation specifications for each model to guide site preparation.

Compressed air supply is the single utility requirement. The manipulator consumes air during the grip and release phases of each cycle, with minimal consumption during transport when the vacuum holding valve maintains suction. Standard shop air at typical fabrication facility pressure satisfies the system requirements without a dedicated compressor.

The modular structure allows the manipulator to be disassembled for relocation. Column, boom, vacuum frame, and base separate into manageable components, enabling shops to move the lifter between bays or facilities without specialized rigging. This modularity also simplifies initial delivery and installation in facilities with limited access doors or overhead clearance.

Metal fabrication facilities processing thick plates and large-format sheets need material handling equipment that sustains heavy loads through continuous shift cycles. Electric hoists and overhead cranes move weight, but they require trained operators, dedicated floor space, and constant chain or sling changes when switching material types. The Herochu heavy duty pneumatic handling system — also functioning as a pneumatic manipulator for sheet metal crane material lifter operations — takes a different approach. It uses compressed air to balance loads up to 500 kg, letting a single operator maneuver large steel plates with minimal physical effort while maintaining full control over positioning and rotation.

Pneumatic Load Balancing for Heavy Materials

The operating principle behind the Herochu HC-RP series is pneumatic equilibrium. Compressed air enters a cylinder that counterbalances the combined weight of the sheet and the lifting arm assembly. When the system is balanced, the load floats — the operator applies gentle directional force to move the sheet through the working area, and the manipulator stops and holds wherever the operator releases. This balance is what distinguishes a pneumatic manipulator from a crane or hoist: there is no pendulum swing, no brake engagement delay, and no creep under load.

For a 500 kg carbon steel plate at 4000 x 2000 mm, this means one person can lift, rotate 220 degrees, and position the sheet on a machine table without strain. The same operation performed with a jib crane and chain sling requires two workers — one to operate the crane and one to guide the load, attach slings, and steady the plate during rotation. The labor savings compound across a production shift where sheet changes happen every few minutes.

Two Model Tiers for Different Load Classes

Herochu offers the pneumatic manipulator in two primary configurations to match different sheet handling requirements:

The HC-RP3015-300 handles sheets up to 3000 x 1500 mm with a 300 kg maximum load capacity. This model suits fabrication shops cutting thin to medium gauge plate — 1 to 8 mm thickness — on laser or plasma cutting beds. The 300 kg ceiling covers most standard sheet sizes in this thickness range, including full 3 x 1.5 meter carbon steel plates at 6 mm gauge.

The HC-RP4020-500 extends the envelope to 4000 x 2000 mm sheets at 500 kg maximum load. This tier targets shops processing thicker plates — 1 to 12 mm or up to 20 mm — where individual sheet weights push past the 300 kg threshold. The larger boom length and column height accommodate the wider material dimensions without reducing the 700 mm lifting stroke that positions sheets at varying machine table heights.

Both tiers share the same 3600 mm column height and 3600 mm boom length, meaning floor space requirements and installation preparation remain consistent regardless of the selected load class.

Safety Architecture for Continuous Operation

Heavy material handling carries inherent risk. A 500 kg plate dropped from any height causes severe equipment damage and personnel injury. The Herochu manipulator integrates multiple safety layers that address these risks at the pneumatic system level.

The emergency air-cut protection system is the primary safety mechanism. When air supply pressure drops below the threshold — whether from compressor failure, hose rupture, or intentional shutoff — a non-return valve immediately seals the vacuum circuit. The sheet remains gripped and suspended, not dropped. Operators can then guide the load down manually at a controlled descent rate. This fail-safe design means a sudden air loss never results in an uncontrolled drop.

The anti-collision device provides a secondary protection layer. When the boom or cup frame contacts an obstruction during movement, the device triggers an immediate stop, preventing the operator from driving the sheet into a machine table edge, storage rack, or adjacent equipment. Combined with the stop-at-any-position holding capability, these protections allow operators to work at sustained pace without the constant vigilance that crane operation demands.

Multi-Material Handling Without Reconfiguration

Metalworking shops rarely process a single material type. A typical day might involve carbon steel sheets in the morning, stainless steel plates after lunch, and aluminum blanks for a rush order in the afternoon. Each material has different surface characteristics, weight profiles, and handling sensitivities.

The Herochu vacuum suction cups handle all these materials without modification. Carbon steel’s slightly rough mill scale provides good vacuum seal texture. Stainless steel’s smooth surface creates an excellent seal. Aluminum and its oxide layer do not compromise cup adhesion. The operator simply picks up the next sheet — no sling changes, no magnet adjustment, no delay between material batches.

This material flexibility extends to plastic sheets as well, broadening the manipulator’s application range beyond pure metalworking into composite and plastics fabrication environments where similar large-format sheet handling occurs.

Structural Engineering for Long-Term Reliability

The manipulator’s column and boom are fabricated from heavy-wall steel tubing, welded and stress-relieved to maintain dimensional stability under repeated heavy load cycles. The base plate anchors to the floor via bolted connections, providing a rigid foundation that prevents column deflection during full-load boom extension.

All pivot bearings are sealed units rated for the dust, vibration, and intermittent oil exposure typical of metal fabrication floors. The vacuum cups are polyurethane — chosen for resistance to cutting fluids, way oils, and surface contaminants on metal sheets. The pneumatic circuit uses fittings and valves rated for industrial air supply conditions, including moisture and particulate content found in non-dedicated shop air systems.

Herochu provides a one-year warranty on the manipulator, covering structural integrity and pneumatic component performance. The warranty reflects the engineering margin built into every load-bearing component — these machines are designed for the daily reality of metal fabrication, not occasional light-duty use.

Economic Justification

The investment in a pneumatic handling system pays back through three channels. First, labor reduction: one operator replaces two at the sheet loading station. Second, cycle time improvement: sheet changes drop from two to three minutes down to under thirty seconds. Third, damage reduction: vacuum cups do not scratch polished surfaces, bend thin sheets, or leave chain sling marks — eliminating rework on material that must meet cosmetic surface standards.

For shops running two or three cutting machines with frequent sheet changes, the combined savings typically justify the equipment cost within the first year of operation.

Manufacturers handling large-format sheet metal face a persistent challenge: moving heavy plates from storage racks to cutting beds without surface damage, operator strain, or cycle bottlenecks. Chain slings scratch polished surfaces. Magnetic lifters fail on thin stainless sheets. Forklift forks bend thin-gauge material. As a pneumatic manipulator for sheet metal crane material lifter applications, the Herochu HC-RP series solves these problems through engineered vacuum suction cup technology that grips, rotates, and places sheet metal with controlled precision across a 3600 mm operating envelope.

Eight-Cup Vacuum Array Configuration

The core of the Herochu HC-RP series manipulator is an eight-group vacuum suction cup array, each cup measuring 200 mm in diameter. This arrangement is deliberate. A single large cup concentrates load stress at one point and fails catastrophically if the seal breaks. Eight cups distribute lifting force across the full sheet surface, maintaining grip even when one or two cups contact a warped edge or an irregularly cut remnant.

The cup count also allows the system to handle varying sheet dimensions. At 1250 x 1250 mm minimum feeding width, the outer cups engage the sheet perimeter. At 3000 x 1500 mm or 4000 x 2000 mm maximum width, all eight cups sit fully under the plate, sharing the load evenly. Operators do not reconfigure the cup array between jobs — the fixed eight-group layout adapts automatically to different plate sizes within the rated capacity.

Sheet Thickness and Material Compatibility

The Herochu vacuum manipulator handles sheet thickness from 1 mm up to 20 mm depending on the configured model tier. Thin 1 mm sheets present a particular challenge: they flex under their own weight, creating gaps where vacuum seals leak. The 200 mm cup diameter provides enough surface contact area to maintain vacuum integrity even on deflecting thin-gauge plates. At the other extreme, 20 mm thick carbon steel plate at 4000 x 2000 mm weighs close to the 500 kg load ceiling — the eight-cup array sustains that mass without seal failure.

Material range extends beyond carbon steel. The cups grip stainless steel, aluminum, and plastic sheets without adjustment. Stainless steel has a smoother surface than carbon steel, which actually improves the vacuum seal. Aluminum’s oxide layer does not interfere with cup adhesion. This multi-material capability eliminates the need for separate handling devices when a fabrication shop processes mixed material types.

Vacuum Circuit and Air Supply Integration

The manipulator operates on pneumatic power, using compressed air to generate vacuum through ejector nozzles rather than relying on electric vacuum pumps. This design choice carries practical advantages on the shop floor. No electrical components sit near the lifting point, reducing spark risk in environments with oil mist or metal dust. The vacuum circuit responds instantly — cups engage when the operator opens the air valve and release when the valve closes, with no pump spin-up delay.

Air consumption stays moderate because the ejector design pulls vacuum only during the grip and release phases. During the transport phase, the vacuum holding valve maintains suction without continuous air draw. This pneumatic architecture also enables the emergency air-cut protection system: if air supply drops suddenly, a non-return valve locks the vacuum circuit and holds the sheet in position, giving operators time to safely lower the load manually.

Lifting Performance and Operating Envelope

The Herochu HC-RP3015-300 model handles sheets up to 3000 x 1500 mm at 300 kg maximum load. The HC-RP4020-500 extends that envelope to 4000 x 2000 mm at 500 kg. Both models share the same 700 mm lifting stroke, 3600 mm column height, and 3600 mm boom length. The 220-degree rotation angle allows the manipulator to pick a sheet from a storage rack, swing it laterally, and place it on a processing table or machine bed without repositioning the column.

The boom rotates and lifts simultaneously, and the system holds position at any point in the arc — there is no drift or sag when the operator releases the controls. This stop-at-any-position capability comes from the pneumatic balance principle: air pressure counterbalances the load weight, so the operator applies only minimal force to move the sheet through space. A 500 kg steel plate moves with the same effort as a 30 kg plate, because the manipulator carries the weight.

Integration with Sheet Metal Workflows

Fabrication shops typically deploy the Herochu pneumatic manipulator at the interface between raw sheet storage and the first processing stage — laser cutting, plasma cutting, or shearing. The manipulator picks plates from horizontal storage racks or vertical cantilever racks, rotates them to the machine table orientation, and places them on the cutting bed. After cutting, the same manipulator can remove cut parts and skeletons from the table, feeding them to the next station.

This continuity eliminates the manual lifting, turning, and positioning that causes musculoskeletal injuries among sheet metal workers. It also shortens the handling cycle: a skilled operator can move a full sheet from rack to machine in under thirty seconds, compared to two or three minutes with a bridge crane and chain sling. For shops running high-mix production with frequent material changes, the speed difference compounds across a full shift.

Structural Design for Shop-Floor Durability

The manipulator’s column and boom are built from welded steel tube sections with machined mounting faces. The modular design allows disassembly for transport or relocation between bays — the column separates from the base, the boom separates from the column, and the vacuum cup frame separates from the boom. A shop that reconfigures its layout can break the unit down, move it, and reassemble it without special rigging equipment.

For operations seeking a heavy steel plate lifting beam supplier, the Herochu boom assembly functions as a dedicated lifting beam with integrated vacuum grip — the rigid steel boom carries the sheet load across its full 3600 mm span while the eight cups hold the plate flat, eliminating the deflection and edge stress that conventional chain-slung beams impose on heavy plates.

Every pivot point runs on sealed bearings designed for the dust and vibration conditions of metalworking environments. The vacuum cups themselves are polyurethane, resistant to oil and cutting fluid contamination. Herochu backs the manipulator with a one-year warranty covering structural and pneumatic components, reflecting the build confidence in a machine designed for continuous daily operation.

Laser cutting machines represent a significant capital investment, and their return depends on sustained beam-on time. Every second the laser head waits for the next plate to be loaded is a second of lost cutting capacity. Manual plate loading into laser cutting machines consumes three to five minutes per sheet — time that accumulates across a shift into hours of idle laser time. The Herochu pneumatic cantilever manipulator is engineered to close this gap, providing automated sheet metal feeding that loads raw plates onto the laser cutting machine table in a fraction of the manual cycle time.

Cantilever Swing Design for Laser Machine Access

The Herochu manipulator employs a cantilever arm that swings horizontally between the raw material platform and the laser cutting machine tabletop. This swing design provides two structural advantages for laser feeding applications.

First, the cantilever geometry keeps the loading mechanism at table height, eliminating the vertical clearance that overhead cranes and gantry loaders require. Laser cutting machines with enclosed safety cabins, exchange tables, or overhead exhaust systems often lack the vertical space for gantry-based loading. The Herochu cantilever arm operates within the horizontal plane, fitting into the gap between the material staging area and the machine cabin without structural modification.

Second, the swing rotation path provides direct access to the laser machine table without intermediate stations. The arm picks up the plate from the raw material platform, rotates to the machine table, releases the plate, and returns — a single-axis motion that is simpler, faster, and more maintenance-accessible than multi-axis robotic arm systems.

Vacuum Suction Feeding for Laser-Quality Surface Protection

Laser cutting demands clean, flat plate surfaces. Scratches, dents, and oil contamination on the plate surface can affect cut quality, cause optical sensor calibration errors, and reduce the effectiveness of the machine’s automatic focusing system. The Herochu manipulator uses vacuum suction cups to grip and transport plates, avoiding the surface damage that mechanical clamps, chains, or magnetic chucks can inflict.

The suction cup configuration scales with plate weight capacity. The HC-R3015-500 model uses 15 cups of 200 mm diameter for plates up to 500 kg. The HC-R3015-1000 model deploys 118 cups of 250 mm diameter for plates up to 1000 kg. The vacuum system distributes the lifting force across the cup array, preventing point-loading that could bend thin gauge plates during the lift and rotation cycle.

Sheet Separation for Thin Gauge Laser Blanks

Laser cutting machines frequently process thin gauge sheet metal — material from 8 mm down to the minimum feeding width of 1250 × 1000 mm. Thin sheets stacked on a raw material platform tend to adhere through surface tension, cutting fluid film, or static charge. When a vacuum system lifts the top sheet, the sheet below often follows, creating a double-plate pickup.

Double-plate loading into a laser cutting machine causes immediate problems. The cutting program is written for a single plate thickness — two plates stacked together double the material thickness, causing the laser to cut incompletely or deflect the beam, potentially damaging the cutting head. The Herochu system addresses this with an integrated sheet separation function. When thin gauge material is selected on the PLC touch screen, the system activates separation before each lift cycle, breaking the adhesion between stacked sheets and ensuring single-plate extraction.

Laser Feeding Cycle Sequence

The standard Herochu cantilever manipulator cycle for laser machine feeding follows this sequence:

Stage 1 — Material preparation. Raw sheet metal plates are staged on the material platform adjacent to the laser cutting machine. The manipulator arm is positioned at the home position above the platform.

Stage 2 — Plate pickup. The suction cup tooling descends and engages the top plate from the raw material stack. The sheet separation function activates for thin gauge material. The vacuum system secures the plate across the suction cup array.

Stage 3 — Rotation to laser table. The cantilever arm rotates to position the plate above the laser cutting machine tabletop. The 2800 mm horizontal stroke provides the reach to span the distance between the staging platform and the machine table.

Stage 4 — Plate release. The arm descends and the vacuum releases, depositing the plate on the machine table in the reference loading position. The arm lifts clear and returns to the raw material platform for the next pickup cycle.

Stage 5 — Cutting and finishing. The laser cutting machine processes the loaded plate. Finished cut parts and skeletons are removed manually or through a secondary handling system, and the cycle repeats.

Safety Systems for Laser Machine Environments

Laser cutting environments combine high-power optical systems, compressed gas supplies, heavy plate loads, and operator access requirements. The Herochu manipulator is engineered with safety systems matched to this environment.

Vacuum retention on utility loss. If electrical power or compressed air is interrupted during the loading cycle, the vacuum system holds the plate on the suction cups for a minimum of five minutes. This retention period prevents a plate from dropping onto the laser machine table, cutting head, or exchange table mechanism during a utility interruption — a critical protection given the replacement cost and alignment sensitivity of laser cutting optics.

Emergency stop braking. The drive system includes automatic braking on emergency stop. When the emergency stop is activated, the arm halts at its current position and resists external force. The braking prevents the arm from swinging into the laser machine cabin, operator walkway, or material platform during an emergency event.

Pneumatic circuit standardization. All gas pipes use a strict color code: blue for air intake, red or orange for air output. Gas pipe connectors carry identification labels. This standardization ensures that maintenance personnel can trace and service the pneumatic circuit without risk of reversing the air supply, which could compromise vacuum system performance.

Bilingual safety documentation. Safety warning labels, maintenance labels, and operation instructions are affixed at key points on the equipment. Button function identifiers are printed in both Chinese and English, supporting deployment in international fabrication facilities.

Plate Capacity and Model Selection

The Herochu cantilever manipulator model lineup covers the plate dimensions and weights common in laser cutting operations:

Facilities cutting standard 3000 × 1500 mm sheets select from the HC-R3015 series. Facilities processing larger structural plates up to 4000 × 2000 mm select the HC-R4020 series. Minimum feeding width across all models is 1250 × 1000 mm, and the power mode is electric throughout the range.

Control System and Operation

The Herochu manipulator operates through a PLC touch screen interface that communicates with the control system via network cable. The touch screen provides access to cycle parameters, suction cup activation sequencing, arm speed control, and mode selection between manual and automatic operation. Operators manage the full loading cycle from this interface — no manual plate feeding is required once the raw material stack is staged.

In automatic mode, the system runs continuous feeding cycles synchronized to the laser cutting machine cycle time. The operator monitors the process from the control panel and manages finished part removal. This single-operator model reduces the labor allocation required for laser machine loading from two or three workers to one, lowering operating costs while sustaining throughput.

Installation, Certification, and Warranty

The manipulator frame is constructed from steel for durability and wear resistance. The modular assembly structure supports efficient installation and disassembly. Herochu provides experienced technical engineers to guide the full installation and commissioning process, including mechanical assembly, pneumatic and electrical connection, PLC configuration, and operator training.

The equipment is produced under factory direct sales at wholesale pricing. OEM and ODM services are available for customized configurations. The system carries CE, ISO, and EU certifications and is backed by a five-year warranty covering structural and drive components under normal operating conditions.

For laser cutting operations seeking to maximize beam-on time through automated plate feeding, the Herochu pneumatic cantilever manipulator provides a safety-engineered, vacuum-suction loading solution that integrates directly with existing laser machine installations and sustains material flow across continuous production cycles.

Heavy plate handling has long been the province of overhead cranes and chain slings—reliable, but slow, imprecise, and rough on the material they move. When a fabricator needs to place a half-ton stainless sheet onto a laser bed, a welding fixture, or a storage slot within a few millimeters of tolerance, conventional lifting gear becomes the limiting factor in the process. The Herochu pneumatic cantilever lifter rethinks this step, substituting balanced pneumatic power and a cantilever arm for brute crane force, and turning heavy plate maneuvering into a controlled, single-operator task.

The Pneumatic Balance Principle

The core of the lifter is a pneumatic balancing system that counteracts the weight of the loaded sheet, bringing it to a near zero-gravity state at the end of the boom. Once balanced, the operator does not lift the plate so much as guide it. A 500 kg carbon steel sheet can be translated across a fabrication zone, rotated into orientation, and lowered onto a target surface with the effort of a push-button command. This shift from muscular effort to guided motion is what separates a pneumatic cantilever lifter from a simple hoist, and it is the reason fabricators deploy the Herochu lifter at workstations where cycle frequency and placement accuracy both matter.

Cantilever Geometry and Working Envelope

A cantilever arm provides reach that a vertical hoist cannot. The Herochu lifter’s boom extends 3600 mm from a 3600 mm column, giving the arm a wide sweep across adjacent machines and storage positions. The 220° rotation angle allows the loaded sheet to swing from a storage stack behind the machine into the cutting or processing envelope without repositioning the column base, and the 700 mm lifting stroke supplies the vertical travel needed to clear machine guards and descend onto beds of varying height. Because the boom is balanced rather than counterweighted with dead mass, the arm holds position at any point in its travel—operators can pause the sheet mid-cycle to verify alignment without fighting drift.

Load Capacity Scaled to the Task

The lifter is engineered for the plate weights that define real fabrication loads rather than laboratory samples. The HC-RP3015-300 handles sheets up to 300 kg at 3000×1500 mm, covering the format most shops run through their lasers and press brakes. The HC-RP4020-500 extends the envelope to 4000×2000 mm plates at 500 kg, the large-format stock used in structural fabrication, trailer bodies, and heavy equipment components. For operations handling bundled or stacked plate at the upper end of the range, the pneumatic balance scales accordingly—the same balanced control that stabilizes a 300 kg sheet governs a 500 kg plate, keeping operator effort constant regardless of load.

Vacuum Interface for Non-Marring Grip

Gripping a polished stainless or aluminum plate with chains or magnets risks the very surface finish the customer is paying for. The Herochu lifter uses an array of eight vacuum cups, 200 mm in diameter, that seal against the sheet face and distribute the load across the plate to prevent sag and edge droop. The cups release on command, so the sheet settles onto the target surface without scraping across it. For shops cutting brushed stainless or anodized aluminum, this non-marring interface is often the single most important justification for the investment, because it eliminates the rework and scrap that mechanical clamping generates.

Emergency Air-Cut Protection

A pneumatic system depends on compressed air, and any air-dependent system must account for supply failure. The Herochu lifter incorporates an emergency air-cut protection system that maintains vacuum on the loaded sheet if the air supply is interrupted, preventing a sudden drop. This is not a convenience feature—in a cell running large plates at height, a dropped sheet endangers the operator, damages the machine bed, and scrapes the material. The fail-safe vacuum retention holds the load long enough for the operator to execute a controlled set-down, which is the safe-state response to any pneumatic interruption.

Ergonomics and Workforce Retention

Manual plate handling is a leading cause of strain injuries in fabrication shops, and the operators who bear that strain are the same experienced workers shops most need to retain. By transferring the lifting force to the pneumatic system, the Herochu lifter converts a physically punishing task into a guided operation a single operator can sustain across a full shift. The reduction in muscular load directly lowers injury rates and absenteeism, and it extends the working life of experienced operators whose expertise is hardest to replace.

Material and Format Versatility

The lifter is not restricted to a single material or plate size. Carbon steel, stainless steel, and aluminum all fall within its handling range, and the modular cup layout can be reconfigured as a shop’s product mix evolves. A workshop that begins by feeding a fiber laser can later deploy the same lifter at a press brake, a plasma table, or a welding station, protecting the capital investment as production priorities shift.

Deployment Scenarios

The pneumatic cantilever lifter fits wherever heavy flat stock must be moved with precision. Common deployments include loading fiber laser cutting beds, transferring plates between storage racks and processing machines, positioning sheets on welding fixtures, and feeding press brakes. In each case, the lifter replaces the two- or three-person crew and the crane or forklift that conventional handling requires, compressing the cycle time and removing the variability that manual placement introduces.

The Herochu Approach to Heavy Handling

The Herochu pneumatic cantilever lifter is built around a straightforward principle: heavy does not have to mean hard. By balancing the load pneumatically, gripping it with vacuum, and maneuvering it on a cantilever arm, the lifter gives a single operator the controlled command of plate that once required a crew and a crane. For fabricators whose throughput is constrained by the loading step rather than the cutting step, that shift in capability is where the return on the investment is realized.

In the fast-paced world of modern metal fabrication, efficiency is not just a goal; it is a currency. Every second saved in material handling translates directly into increased throughput and higher profit margins. For workshop managers and production engineers seeking to bridge the gap between manual labor and full automation, the introduction of the Herochu Electric Cantilever New Pneumatic Manipulator marks a significant leap forward. This machine is engineered specifically to address the bottlenecks associated with loading and unloading sheet metal, offering a blend of lightweight agility and industrial-grade robustness that is rare in the current market.

The structural design of the Herochu manipulator is one of its most compelling features. Unlike traditional, bulky material handlers that require extensive floor space and complex installation, this unit boasts a light structure that is remarkably easy to disassemble and assemble. This does not mean a compromise on durability; rather, it signifies a shift towards modular engineering. The cantilever design provides a wide operational envelope without the need for heavy counterweights, allowing it to be integrated into existing production lines with minimal disruption. This adaptability makes the Herochu Electric Cantilever New Pneumatic Manipulator for Sheet Metal an ideal solution for small to medium-sized enterprises that require flexibility, as well as large-scale facilities looking to optimize their material flow without overhauling their entire workshop layout.

Performance metrics are where this machine truly distinguishes itself. Equipped with high-torque servo drives, the system ensures that every movement, whether rotating, lifting, or traversing, is executed with a smoothness that protects the integrity of the material surface and the precision of the equipment. The handling cycle is exceptionally short, significantly reducing the downtime between machining operations. Operators can halt the motion at any position, allowing for easy, fast, and continuous handling. This is crucial for complex fabrication tasks where different stages of processing require varying angles and positions.

Safety and reliability are non-negotiable in heavy industrial environments. The Herochu manipulator integrates advanced fail-safe mechanisms to protect both the operator and the material. It includes an active air pressure protection system, or pneumatic fail-safe, which ensures that in the event of a pressure drop, the load is secured instantly. Furthermore, an emergency braking module complements this system, locking the load in place to prevent accidental drops. This high safety performance, coupled with anti-collision devices, makes the manipulator a safe choice for busy workshops.

Versatility is at the core of the Herochu range, as evidenced by the diverse specifications available. Models such as the HC-PR3015-300 and HC-PR3015-500 offer maximum feeding widths of 3000mm by 1250mm, handling plate thicknesses of 8mm and 12mm respectively. For heavier duties, the HC-PR3015-1000 can manage up to 20mm thick plates with a maximum weight of 1000kg. Larger formats are also catered to with the HC-PR4020 series, extending to 4000mm by 1250mm. This variety allows manufacturers to select a Crane & Material Handling Lifter that matches their specific operational requirements, ensuring they are not overpaying for unnecessary capacity while still having room for growth.

The power mode options, available in both pneumatic and electric variants, offer further customization based on the facility’s existing infrastructure. The intelligent PLC control system is designed for seamless synchronization with CNC software, allowing for real-time monitoring and easy programming. By automating the loading process with this Herochu manipulator, facilities can eliminate manual handling delays, ensuring that expensive laser cutters and presses operate at peak capacity 24/7. The result is a rapid material turnover that allows businesses to take on more orders without increasing operational hours, directly impacting the bottom line.

The productivity of any CNC machining operation hinges on a single, often overlooked factor: material loading speed. Every minute spent manually maneuvering heavy steel plates onto a laser cutter bed or positioning sheets against a press brake stop is a minute of lost machine utilization. For fabricators operating in competitive markets, this inefficiency directly erodes profit margins and constrains throughput capacity.

Herochu has engineered a response to this persistent challenge with the Pneumatic Cantilever Loading Manipulator—a purpose-built material handling system that transforms the way sheet metal enters the processing workflow. Unlike conventional overhead cranes or forklift-based loading methods, this manipulator provides operators with precise, effortless control over heavy materials, enabling rapid positioning with minimal physical exertion.

This article examines the engineering principles, operational advantages, and measurable return on investment that make the pneumatic cantilever loading manipulator an indispensable asset for modern CNC sheet metal fabrication facilities.

The Cantilever Advantage: Why Design Matters

The fundamental distinction between a standard pneumatic manipulator and a cantilever loading manipulator lies in the arm geometry. A conventional manipulator lifts from directly above the load, requiring the lifting point to be positioned precisely over the material’s center of gravity. This constraint limits reach and complicates loading into machine enclosures or across wide processing tables.

The cantilever configuration, by contrast, extends outward from a vertical pivot column, creating a horizontal arm that can reach over safety guards, into laser cutter enclosures, and across expansive machine beds. This reach capability is essential for CNC feeding because the processing equipment often sits several feet from the material storage area.

Beyond reach, the cantilever design provides inherent stability when handling off-center loads. Plates being loaded into CNC machinery rarely position themselves perfectly under the lifting point. The cantilever’s torque-absorbing architecture keeps the load level even when the center of gravity shifts, preventing edge binding during insertion and ensuring smooth, damage-free material placement.

Herochu’s implementation of this design philosophy results in a manipulator that combines structural rigidity with operational flexibility. The high-strength steel fabrication delivers a lightweight self-weight while maintaining the capacity to handle substantial loads. This balance of strength and agility is what allows operators to maneuver heavy plates with the same ease as handling a hand tool.

Technical Specifications and Configuration Options

The Herochu Pneumatic Cantilever Loading Manipulator is available in multiple configurations to accommodate varying sheet sizes and weight requirements. Standard models handle maximum plate weights from 300 kilograms to 1,000 kilograms, with feeding plate thickness capabilities ranging from 8 millimeters to 20 millimeters depending on the configuration.

Typical sheet dimension capacities include 3000×1500mm and 4000×2000mm formats, covering the vast majority of sheet sizes encountered in construction, signage, machinery manufacturing, and general metal fabrication. The manipulator achieves a 220-degree rotation angle and a 700-millimeter lifting stroke, providing comprehensive coverage of the work envelope around the processing equipment.

The suction cup array—typically comprising 8 groups with 200-millimeter diameter cups—is scientifically configured to accommodate panels across a spectrum of sizes, finishes, and weight ranges. This ensures a secure and reliable grip whether handling carbon steel, stainless steel, or aluminum plates.

Operational Principles: Pneumatic Power with Human Intelligence

The core philosophy behind the Herochu Pneumatic Cantilever Loading Manipulator is amplification of human capability, not replacement of it. The system is meticulously balanced, requiring operators to apply only minimal force to control the workpiece’s position in any spatial orientation with pinpoint accuracy.

Powered by compressed air, the manipulator uses cylinders and valves to drive its swing arm through preset motions—lifting, rotating, and placing sheets with consistent force. Control is executed via a handheld pendant with push-button or joystick inputs, allowing the manipulator to respond instantly to human direction. This intuitive control interface is ideal for dynamic job shops where material types and sizes change frequently.

The pneumatic power source offers distinct advantages over fully electric systems in demanding industrial environments. With fewer electronic components, the pneumatic manipulator reduces maintenance complexity and demonstrates greater tolerance to dust, moisture, and temperature swings. These characteristics make it particularly suitable for harsh workshop conditions where electronic systems might be compromised.

Safety Systems: Engineering Protection into Every Movement

Safety is not an afterthought in the Herochu pneumatic cantilever loading manipulator—it is engineered into the fundamental architecture of the system. The manipulator incorporates multiple layers of protection to safeguard both operators and materials.

The emergency air-cut protection system is a critical feature that maintains holding pressure for an extended duration during sudden power failures. When the air supply is interrupted, valves lock the arm in place, preventing uncontrolled drops and protecting the workpiece from damage. This fail-safe operation ensures that even in the event of a pneumatic system failure, the load remains secure.

Additional safety features include anti-collision devices and real-time pressure monitoring that provides continuous feedback on suction integrity. These systems work in concert to create a handling environment where operator safety is never compromised for the sake of productivity.

Applications Across the Sheet Metal Industry

The versatility of the Pneumatic Cantilever Loading Manipulator makes it applicable across a broad spectrum of sheet metal processing operations. Its primary function is to automatically transport raw materials—steel sheets, metal plates, and other flat substrates—to the work table of processing equipment with pinpoint accuracy.

Laser cutting operations benefit from the manipulator’s ability to feed plates rapidly and consistently into the cutting envelope. By reducing the handling cycle from minutes to seconds, the system maximizes laser cutter uptime and ensures that the cutting head never waits for material.

CNC punching and shearing applications leverage the manipulator’s precision positioning capabilities. The ability to stop at any position within the work envelope allows operators to align sheets exactly against machine stops, improving part accuracy and reducing scrap.

Press brake operations utilize the manipulator for both loading and repositioning. The effortless control over heavy plates enables single operators to manage materials that would otherwise require multiple personnel, significantly reducing labor dependency.

Economic Impact and Return on Investment

The financial case for implementing a pneumatic cantilever loading manipulator is compelling. Facilities handling high volumes of sheet material typically achieve payback periods measured in months rather than years, driven by multiple concurrent savings streams.

Machine utilization improvement represents the most immediate benefit. By reducing loading times from minutes to seconds, the manipulator ensures that high-value processing equipment operates closer to its theoretical capacity. For a laser cutter costing hundreds of dollars per hour to operate, every additional minute of cutting time translates directly to increased revenue.

Labor cost reduction is equally significant. A single operator equipped with a pneumatic manipulator can accomplish material handling tasks that would otherwise require multiple personnel. This not only reduces direct labor costs but also mitigates the challenges of recruiting and retaining skilled workers for physically demanding roles.

Material savings accrue from damage prevention. The vacuum suction cup approach distributes holding force evenly across the sheet surface, eliminating the marks, scratches, and deformations associated with mechanical clamping. For high-value materials such as stainless steel or aluminum, this protection translates to substantial reduction in scrap and rework costs.

Worker compensation and ergonomic benefits contribute to the long-term ROI. By removing workers from the physically demanding task of manual sheet handling, the manipulator reduces the incidence of musculoskeletal injuries and the associated costs of worker compensation claims.

Integration with Existing Workflows

A key consideration for any capital equipment investment is the ease of integration with existing operations. The Herochu Pneumatic Cantilever Loading Manipulator is designed for seamless incorporation into established workflows.

The column-mounted configuration occupies minimal floor space, making it suitable for workshops where real estate is at a premium. The modular design facilitates rapid assembly and disassembly, allowing the manipulator to be relocated as production layouts evolve.

For facilities handling high volumes, the pneumatic cantilever loading manipulator works in concert with automatic sheet storage systems, creating an integrated material flow from raw stock to finished part. This integration capability ensures that the manipulator remains a valuable asset as operations scale and automation levels increase.

Conclusion

The Pneumatic Cantilever Loading Manipulator represents a fundamental advancement in CNC sheet material handling. By combining the reach and stability of cantilever geometry with the precision and safety of pneumatic control, Herochu has created a system that addresses the core challenges of modern metal fabrication: throughput, quality, and worker safety.

For fabricators seeking to eliminate the material handling bottleneck that constrains machine utilization, this manipulator offers a proven, cost-effective solution. Its combination of robust construction, intuitive operation, and comprehensive safety systems makes it an essential investment for any facility committed to operational excellence in sheet metal processing.

In modern sheet metal fabrication, the efficiency of loading raw materials into a laser cutting machine directly determines throughput and labor costs. The Herochu Feed Laser Machine Pneumatic Cantilever Loading Manipulator is engineered to bridge the gap between manual handling and fully automated systems. This cantilever-style manipulator combines pneumatic power with intuitive control, enabling operators to lift, transfer, and position metal plates weighing up to 1000 kg onto the cutting bed with minimal physical effort. Unlike conventional forklift-based or overhead crane methods, this manipulator offers precise spatial control, emergency air-cut protection, and a modular design that adapts to various shop floor layouts.

Herochu has focused on solving three common pain points in laser cutting feeding: slow cycle times, safety risks during plate placement, and damage to material surfaces. The HC-PR series manipulator addresses each through a vacuum suction cup array, anti-collision devices, and a cantilever structure that allows 220-degree rotation and a lifting stroke of 700 mm. This article provides a detailed technical examination of the pneumatic cantilever loading manipulator, its operational principles, parameter configurations, and why it outperforms conventional feeding methods.

Core Design Philosophy

The Herochu feed laser machine pneumatic cantilever loading manipulator is built on a lightweight yet rigid aluminum alloy frame. The cantilever arm extends up to 3600 mm from the column, covering standard sheet sizes from 1250×1250 mm to 4000×2000 mm. The pneumatic power mode uses compressed air to drive the lifting and rotation actuators, offering a clean and explosion-proof solution ideal for environments with laser equipment.

Key design elements include:

• Modular assembly/disassembly: The arm, column, and suction head can be separated for maintenance or relocation.

• Emergency air-cut protection: If air pressure drops below the safe threshold or a power failure occurs, the system automatically locks the load in position, preventing sudden drops.

• Position-hold capability: The manipulator stops at any height or rotation angle without drift, thanks to a balanced pneumatic circuit.

Technical Specifications

The rotation angle on all models reaches 220 degrees, while the lifting stroke is standardized at 700 mm. Column height stands at 3600 mm, and the boom length matches 3600 mm. These dimensions allow the manipulator to service laser cutting machines with working areas up to 4 meters in length.

Operational Workflow

When feeding a laser cutting machine, the operator first positions the suction cup assembly over a stack of carbon steel, stainless steel, or aluminum sheets. A PLC touch screen interface – standard on electric-equipped models – allows selecting between manual or semi-automatic modes. Pressing the activation button engages the vacuum generator, and eight suction cups (200 mm diameter each) create a distributed grip on the plate surface.

For plates thinner than 3 mm, the Herochu manipulator incorporates an optional sheet separation function. A burst of compressed air or a mechanical lifter breaks the vacuum between stacked sheets, preventing double picking. Once the plate is secured, the operator guides the cantilever arm horizontally – requiring less than 3 kg of force due to pneumatic balancing – and rotates it toward the laser cutting machine’s worktable. Releasing the vacuum at the target position completes the loading cycle.

The entire handling cycle from pick to place averages 15 to 25 seconds, depending on travel distance. Compared to manual two-person lifting (which takes 45–60 seconds and risks back injuries), the Herochu pneumatic cantilever loading manipulator doubles throughput while eliminating workplace accidents.

Safety Features

Herochu prioritizes operator and equipment safety through multiple layers:

• Air cut-off protection: Monitors supply pressure in real time. If pressure falls below 4 bar, the system holds the load and sounds an alarm.

• Anti-collision device: Proximity sensors on the arm prevent impact with the laser cutting machine’s gantry or other obstacles.

• Suction cup vacuum redundancy: Each cup operates independently; losing one cup still leaves sufficient grip for 70% of rated load.

• Soft start/stop: Pneumatic flow control valves eliminate jerky movements that could shift the plate or damage the cutting head.

Application Examples

Case A – 6 kW fiber laser cutting 8 mm carbon steel: A job shop using the HC-PR4020-500 model reduced loading time from 50 seconds per sheet to 18 seconds. The manipulator’s 500 kg capacity allowed stacking three 8 mm sheets (each 150 kg) for batch processing, though single-sheet feeding is recommended for precision.

Case B – Aluminum plate processing: Aluminum’s softer surface requires careful suction. Herochu’s 200 mm cups with polyurethane seals leave no marks, maintaining surface finish integrity.

Why Choose Herochu for Laser Cutting Feeding

Herochu manufactures the feed laser machine pneumatic cantilever loading manipulator in an ISO 9001-certified facility. Each unit undergoes a 48-hour burn-in test under full load.
