Workshops that process aluminum profiles face a persistent storage challenge. Extrusions arrive in bundled lengths of 6 meters and longer, requiring floor space that production lines cannot spare. Stacking profiles against walls bends the bottom layers, scratches anodized surfaces, and forces operators to spend minutes — sometimes longer — locating the correct alloy and dimension. The Herochu heavy duty aluminum profile cantilever storage rack resolves these issues by giving each profile batch a dedicated, accessible tier that extends directly to the operator on demand.
Structural Foundation Built for Continuous Workshop Loads
Every Herochu cantilever rack begins with a Q235B high-strength steel frame. Q235B is specified because it maintains yield integrity under repeated point loading — the exact condition created when a forklift deposits a 3-ton bundle onto a single arm tier. The dual-beam crossbar design distributes that load across both upright columns, preventing the torsional fatigue that single-beam configurations suffer after thousands of loading cycles. For workshops running two or three shifts, this structural margin translates into decades of service without frame realignment.
The base plate anchors to the workshop floor through heavy-duty expansion bolts, creating a rigid foundation that resists lateral movement during telescopic extension. Each upright column is welded to the base in a single continuous pass — not tack-welded and finished — eliminating the micro-fracture initiation points that develop at interrupted welds under vibration. The Herochu manufacturing team conducts ultrasonic weld inspection on every column before assembly, ensuring that the structural weldments meet the load ratings stamped on the identification plate.
Telescopic Operation: Extending Only the Tier You Need
Conventional fixed cantilever racks require a forklift turning aisle along the entire rack length. The Herochu telescopic mechanism eliminates this requirement. When an operator needs profiles from tier three, only that tier extends outward. The remaining tiers stay retracted, occupying minimal floor depth. When the retrieval is complete, the tier slides back flush with the rack body.
This selective extension produces two measurable outcomes:
- Floor area savings: Storage density reaches 2–3 times that of traditional cantilever racks within the same factory footprint.
- Material handling speed: A single operator can extend the target tier, pick the required bundle, and retract the tier in under three minutes.
The drive system offers two configurations. The hand-cranked version uses a gear-and-rack transmission with a mechanical advantage ratio that keeps handle force below 15 kg even at full 3,000 kg load. The electric version adds a one-button start motor with a limit switch that halts extension at the safe travel endpoint, preventing over-travel damage.
Tier Classification for Aluminum Profile Management
Aluminum profiles enter the workshop in dozens of cross-sections — T-slot profiles, angle stock, rectangular tube, and custom extrusions. The Herochu rack supports classified storage by assigning each extrusion type to a dedicated compartment. Both sides of the rack provide independent tiers, so an operator retrieving 40×40 mm T-slot profiles from the front does not disturb 80×80 mm structural profiles stored on the rear tiers.
| Model | Pipe Length | Max Load per Level | Number of Layers | Clear Space |
|---|---|---|---|---|
| HC-G6053S | 6,000 mm | 3,000 kg | 5 (customized) | 600 mm (customized) |
| HC-G6053 | 6,000 mm | 3,000 kg | 5 (customized) | 600 mm (customized) |
The 6,000 mm pipe length covers standard aluminum extrusion deliveries, which are typically cut to 6 meters at the mill. The 600 mm clear space between uprights accommodates most profile bundle widths. Where a workshop handles oversized extrusions, Herochu customizes the clear space, pipe length, and tier count to match the specific inventory profile — no two workshop storage layouts are identical, and the rack configuration should reflect that reality.
Surface Protection for Anodized and Mill-Finish Profiles
Aluminum profiles arrive with surface finishes that range from mill finish (raw extrusion oxide) to anodized and powder-coated treatments. Contact with bare steel arms during storage can deposit iron particles that initiate galvanic corrosion on the aluminum surface. The Herochu rack addresses this through a two-stage surface treatment on all contact surfaces.
First, the steel arms and uprights receive an electrostatic powder-coated finish that creates a non-conductive polymer barrier between the steel substrate and the aluminum payload. This coating is applied through a fluidized bed process that achieves 60–80 μm thickness with uniform coverage on complex geometries including the arm-to-column junction. Second, galvanized steel cantilever arms are available for workshops operating in humid environments where coating integrity might be compromised by condensation.
The plug-in design of the cantilever arms allows surface replacement without disassembling the rack. If an arm coating is damaged by a forklift impact, the operator removes two retaining pins, slides out the damaged arm, and inserts a replacement — a five-minute operation that restores full surface protection.
Workshop Integration with Existing Material Handling Equipment
The Herochu rack is engineered to interface with the equipment already present in the workshop: forklifts, overhead cranes, and vacuum lifting devices. The extended tier positions the payload at a height that matches standard forklift fork entry — typically 300–400 mm above the tier surface — eliminating the need for specialized low-clearance forks. For workshops with overhead cranes, the tier height can be configured to bring the payload within the crane’s hook travel range, allowing direct lifting without a forklift intermediary.
Material preparation time drops significantly in this configuration. Rather than unstacking profiles, carrying them to a cutting station, and restacking the remainder, the operator extends the tier, picks the required length directly, and feeds it to the saw line. The profiles that remain stay secured in their compartment, undisturbed by the retrieval operation.
Installation and Relocation
Workshop layouts change. Production lines get reconfigured, new equipment arrives, and storage zones shift. The plug-in design that simplifies arm replacement also simplifies rack relocation. Each rack module bolts together without permanent welds between modules, allowing a complete disassembly and reassembly within a single shift. Herochu provides installation drawings that specify floor preparation, bolt patterns, and torque values for each model, so the relocation can be performed by the workshop’s own maintenance team without external contractors.
Customization Parameters
Herochu builds each rack to the workshop’s operational specification. The standard parameters open for customization include:
- Tier count: Standard 5 or 6 layers; configurable from 3 to 8 layers depending on ceiling height and forklift lift capacity.
- Clear space: 600 mm standard; adjustable to accommodate bundle widths from 400 mm to 1,200 mm.
- Load per level: 3,000 kg standard for the HC-G6053 series; upgradeable to 5,000 kg for workshops handling solid bar stock or heavy-wall profiles.
- Drive type: Hand-cranked for cost-sensitive applications; electric for high-throughput operations where cycle frequency exceeds 20 extensions per shift.
- Surface finish: Electrostatic powder coating in standard workshop gray; custom RAL colors available for facilities using color-coded storage zones.
Operational Safety
Each tier incorporates a mechanical locking mechanism that engages at full extension, preventing inadvertent retraction while an operator’s hands or a forklift is within the tier envelope. The lock releases only through deliberate operator action — a pull handle on the tier face — ensuring the tier cannot collapse inward under load. The gear-and-rack transmission in hand-cranked models includes a self-locking worm gear ratio, so the tier holds position if the operator releases the crank mid-extension.
For the electric drive, a redundant limit switch system cuts motor power at the travel endpoint. If the primary switch fails, a secondary mechanical stop absorbs the residual travel force, protecting the motor and transmission from overload.
Why the Herochu Rack Fits the Workshop Environment
Workshop storage is not a warehouse-scale problem. It is a daily, operational challenge where speed of access, protection of material surface finish, and adaptability to layout changes matter more than raw cubic capacity. The Herochu heavy duty aluminum profile cantilever storage rack addresses each of these priorities through selective tier extension, surface-compatible arm treatments, and a modular plug-in architecture that grows and moves with the workshop.
For workshops processing 6-meter aluminum extrusions at volumes that justify classified storage, the HC-G6053S and HC-G6053 models provide the load capacity, tier flexibility, and drive options that match real production environments — not theoretical storage calculations.
