Industrial warehouses handling steel bars and pipes face a persistent challenge: storing long, heavy materials without wasting floor space or sacrificing retrieval speed. The Herochu Heavy Duty Telescopic Cantilever Rack solves this through a manually crank-driven telescopic arm system that extends outward on demand and retracts flush when not in use, eliminating the wide forklift aisles that fixed-arm racks demand.
Telescopic Arm Drive Mechanism
Each cantilever arm on the Herochu rack connects to a gear-and-rack drive train activated by a hand crank. Turning the crank extends the arm by 70% to 99% of its retracted length, pushing stored material out from the column face for direct pickup. Once loading or retrieval finishes, the arm retracts back into the rack footprint. No electric motor, no hydraulic pump, no control panel—just mechanical drive that runs without power and requires minimal maintenance.
Because arms operate independently at each tier, an operator can pull out one storage level without disturbing bundles on the levels above or below. This selective extension reduces handling damage to steel bar stock and cuts the time spent searching for a specific grade or diameter buried in a multi-tier rack.
Load Ratings and Structural Engineering
The Herochu frame is welded from Q235B high-strength steel and reinforced with a dual-beam crossbar design that spreads load evenly across the column assembly. A single arm carries up to 500 kg. Per-level capacity reaches 3,000 kg on the HC-G6053 and HC-G6053S models, and 5,000 kg on the HC-G9065 and HC-G12065 models.
The dual-beam crossbar resists lateral deflection under full load—a critical structural factor when 6-meter steel bars generate lever-arm forces on extended cantilevers. Base plates anchor each column to the floor, sized to the rated load of the specific model, preventing column drift under repeated loading cycles.
Space Savings and Warehouse Layout
Standard cantilever racks need a forklift aisle of 3.5 to 4 meters between rows. The Herochu telescopic design cuts that footprint because arms extend only during active handling. In the retracted position, adjacent racks sit closer together, reclaiming more than 30% of floor area compared to fixed-arm configurations.
This compact layout serves facilities where space is tight: metal service centers, fabrication shops, building material yards. Single-sided units mount against walls; double-sided units sit back-to-back in central aisles. The configuration adapts to existing traffic patterns rather than forcing a warehouse redesign.
Material Handling Versatility
The Herochu telescopic cantilever rack stores both bundled and loose materials. Bundled steel bars, seamless pipes, copper rods, and aluminum profiles all rest securely on the flat arm surfaces. The 600 mm clear spacing between arms—customizable at the factory—fits a range of bundle diameters. Independent compartments at each tier let operators segregate stock by grade, diameter, or project code without physical contact between material groups.
Powder Coating and Corrosion Protection
Every structural component receives a powder-coated finish applied after welding and fabrication. The coating resists corrosion in humid storage environments and chemical-laden air typical of galvanizing plants and coastal distribution centers. Combined with the Q235B steel substrate, the finish extends rack service life and reduces the frequency of repainting cycles.
Model Specifications
| Model | Pipe Length (mm) | Max Load per Level (kg) | Tiers |
|---|---|---|---|
| HC-G6053S | 6,000 | 3,000 | 5 (custom) |
| HC-G6053 | 6,000 | 3,000 | 5 (custom) |
| HC-G9065 | 9,000 | 5,000 | 6 (custom) |
| HC-G12065 | 12,000 | 5,000 | 6 (custom) |
The HC-G6053S handles 6-meter stock at moderate loads. The HC-G12065 accommodates 12-meter bars with 5,000 kg per-level capacity. Tier count and arm spacing are set at the factory based on the customer’s material inventory profile.
CE Certification and Pre-Shipment Testing
The Herochu telescopic cantilever rack carries CE certification, confirming structural compliance with European safety standards. Each unit undergoes load testing before shipment to verify that the rack holds its rated capacity under controlled conditions. This pre-delivery verification gives warehouse managers documented assurance that the equipment will perform as specified on the first day of operation.
Summary
For facilities storing steel bars and pipes in constrained floor space, the Herochu telescopic cantilever rack pairs heavy load capacity with mechanical simplicity. The hand-crank drive, Q235B dual-beam structure, and independent tier compartments deliver organized, accessible storage without electric dependency or wide aisle requirements—making it a practical choice for metal processors, distributors, and fabricators managing long-material inventory.
