Modern sheet metal fabrication cells group machines that cut, punch, and form at high speed, but the equipment that feeds those machines is too often an afterthought. When a 500 kg plate must move from storage to a fiber laser bed, from a cutting cell to a press brake, or from a rack to a welding fixture, the handling step is where throughput stalls and material gets damaged. The Herochu high load sheet metal manipulator is built to serve as the auxiliary feeding equipment that closes this gap—positioning heavy plate with the precision the primary CNC machines demand.

The Role of Auxiliary Feeding Equipment

Auxiliary feeding equipment is the connective tissue of a fabrication cell. The fiber laser, the punch press, and the press brake each perform their primary function well, but none of them loads itself. A high load manipulator takes ownership of the loading, unloading, and transfer motions that surround the primary cutting or forming cycle, so the primary machine spends its time on value-adding work rather than waiting for material to arrive. In a well-balanced cell, the manipulator’s cadence sets the pace the rest of the equipment follows.

High Load Capacity for Real Fabrication Weights

Fabrication stock is heavy. A 4000×2000 mm carbon steel plate in a typical gauges exceeds the safe manual handling threshold by a wide margin, and even a 3000×1500 mm sheet challenges a two-person crew across a full shift. The Herochu manipulator is rated for the loads that define real production rather than sample weights. The HC-RP3015-300 handles sheets up to 300 kg at 3000×1500 mm, and the HC-RP4020-500 extends to 4000×2000 mm plates at 500 kg. These capacities cover the standard and large-format stock that flows through most fabrication shops, so the manipulator is sized to the job rather than forcing the job to fit the tool.

Technical Specifications

The shared geometry across both models—220° rotation, 700 mm stroke, 3600 mm column and boom—means a shop operating both formats applies one set of operating procedures, one maintenance routine, and one operator training program across its handling fleet. Standardization lowers the cost of ownership and shortens the learning curve when the equipment is deployed across multiple workstations.

Precision Positioning for CNC Integration

A manipulator is only useful to a CNC cell if it can place a sheet where the machine expects it. The Herochu manipulator’s balanced boom holds position at any point in its 700 mm stroke and 220° rotation, so the operator can stop the sheet mid-cycle to align it against the bed’s reference pins before committing to the descent. The controlled vertical motion lands the sheet at bed height without impact, preserving both the sheet edge and the machine’s support slats. This positional control is what distinguishes auxiliary feeding equipment from a general-purpose hoist, and it is the capability that lets the manipulator feed a laser, a punch, or a brake with equal competence.

Vacuum Grip for Multi-Material Compatibility

Feeding equipment that handles only one material is a constrained investment. The Herochu manipulator uses eight vacuum cups, 200 mm in diameter, arranged to balance the load across the sheet face. This interface grips carbon steel, stainless steel, and aluminum—polished, brushed, or mill finish—without mechanical clamps that could mark the surface. The cups release on command, so the sheet settles onto the bed without dragging across it, which preserves the finish the downstream CNC process depends on. When a shop’s product mix shifts between materials, the vacuum layout adapts without retooling the grip mechanism.

Modular Structure for Flexible Deployment

The manipulator’s modular design supports assembly and disassembly without specialized rigging, which matters in shops where the equipment must be relocated as cell layouts evolve. The boom, column, and vacuum array are built as interchangeable modules, so a manipulator deployed at a laser cell this quarter can move to a press brake station next quarter as production priorities change. This modularity also simplifies maintenance—worn components are replaced at the module level rather than requiring wholesale disassembly, which keeps downtime to the short windows a production schedule allows.

Safety Under Load

Handling heavy plate is inherently hazardous, and the manipulator is designed to contain that hazard through its structure and controls. The emergency air-cut protection system retains vacuum on the loaded sheet if the compressed-air supply is interrupted, preventing an uncontrolled drop. The balanced cantilever means a single operator guides the load with minimal force, and the ability to stop the sheet at any position lets the operator verify clearance and alignment before completing the motion. These features reduce the dropped-load and strain injuries that disrupt fabrication cells and inflate labor and insurance costs.

Workstation Ergonomics

Beyond raw safety, the manipulator reshapes the physical demand of the loading task. Manual plate handling drives strain injuries and accelerates operator fatigue, which erodes both output and workforce retention. By transferring the lifting force to the equipment and reducing the operator’s role to guided control, the Herochu manipulator converts a punishing task into a sustainable one. A single operator can run the loading cycle across a full shift at consistent speed, which stabilizes the cell’s output and extends the working life of the skilled personnel shops most need to keep.

The Scope of Auxiliary Equipment

Auxiliary feeding equipment is easily undervalued because it does not cut, punch, or form the part. Yet every minute a primary machine waits for material is a minute of paid capacity lost, and every sheet damaged in transfer is material and machine time wasted. The Herochu high load sheet metal manipulator addresses both losses. It feeds the cell at the cadence the primary machines were specified to run at, and it moves the material without the surface and edge damage that generates scrap. For fabricators whose bottleneck is the loading step rather than the cutting step, that is where the return on the investment is found.

The Herochu Standard for High Load Handling

Herochu engineered its high load manipulator to the same standard shops apply to their primary CNC equipment: rated for real production weights, precise in placement, modular in deployment, and safe under load. For fabrication cells whose throughput is governed by how fast and how accurately sheet metal reaches the machine, the manipulator is the auxiliary equipment that brings the feeding step up to the capability of the cutting and forming steps—and that alignment is where the cell reaches the output it was designed to deliver.
