Traditional fixed-arm cantilever racks, while robust, present a limitation: the arms occupy permanent space even when not loaded. For warehouses handling multiple material lengths or requiring frequent reconfiguration, this rigidity becomes a bottleneck. Herochu engineered the Adjustable Movable Storage Telescopic Cantilever Rack to overcome this constraint. Combining telescopic arm technology with movable base frames, this system allows operators to extend arms only when needed, retract them for aisle clearance, and even reposition entire rack modules across the warehouse floor.

The term “adjustable movable storage” encompasses two distinct capabilities: first, the telescopic arms extend and retract along linear slides (manual or electric); second, the rack structure itself can be moved (on rail systems or with forklift pockets) to reconfigure storage lanes. Herochu’s design prioritizes ease of adjustment without sacrificing load capacity—each telescopic arm still supports 500–2000 kg, depending on the model.

Core Technical Features

Herochu’s adjustable movable storage telescopic cantilever rack starts with a carbon steel upright (standard 3000 mm height) and a heavy-duty base. The telescopic arms are constructed from nested steel sections with precision-ground rollers and hardened rails. Extension is achieved either manually via a pull-handle (for lighter loads up to 800 kg per arm) or electrically with a linear actuator (for loads up to 2000 kg per arm). Electric versions include a remote control or push-button panel, allowing single-operator access to materials stored 6 meters deep.

Arm length standard range is 800 mm to 1500 mm, but Herochu custom-fabricates arms up to 2000 mm fully extended. The retracted length reduces the arm’s footprint by 40–60%, turning a 1500 mm arm into a 600 mm protrusion when not in use. This feature is invaluable for narrow-aisle warehouses where every centimeter matters.

The “movable” aspect is achieved through two optional systems: a rail-guided carriage system (similar to mobile shelving but rated for heavy duty) or integrated forklift pockets in the base. Rail-guided racks move manually with a handwheel or via motorized drives, compressing multiple storage lanes into a single access aisle. Forklift-moveable racks allow seasonal reconfiguration—for instance, moving the rack from a receiving area to a long-term storage zone.

Surface Treatment and Durability

Given that telescopic mechanisms have moving parts, Herochu applies a two-layer protection system: zinc plating on all roller components and slides, plus a powder-coated or galvanized finish on static structural elements. This combination prevents galling and corrosion while maintaining smooth extension even after years of dusty or humid operation. The varnished option is available for indoor clean environments, but for heavy industrial use, we strongly recommend galvanization.

Operational Advantages Over Fixed Cantilever Racks

1. Dynamic aisle management: In a fixed cantilever rack, the aisle must be as wide as the longest arm. With telescopic arms, you can maintain a narrow main aisle (e.g., 1.5 meters) and extend arms only into the aisle during loading/unloading. After retrieval, arms retract, restoring the full aisle width for forklift traffic.

2. Multi-length material storage: A single telescopic rack can store short materials (arms retracted) and long materials (arms extended) on different levels. This eliminates the need for separate rack systems.

3. Movable configuration for seasonal SKUs: If your product mix changes—say, longer pipes in winter and shorter profiles in summer—you can reposition the movable rack bases to create variable-depth storage cells.

4. Integration with automated cranes: Electric telescopic arms can be interfaced with warehouse control systems (WCS). When a crane positions itself at a specific column, the arm automatically extends to the preset length, allowing hands-off retrieval.

Safety and Load Stability

Some engineers worry that telescopic arms might be less stable than fixed arms. Herochu addresses this with a positive locking mechanism: once the arm is extended to the desired length, a spring-loaded pin engages into pre-drilled holes on the inner slide, preventing accidental retraction under load. The arm also features a slight upward camber (approx. 2 mm per meter) so that under full load, it deflects to level, not downward. Each telescopic cantilever rack is tested at 125% of rated capacity before leaving the factory.

Application Scenarios Best Suited for Adjustable Movable Storage

• Metal service centers that handle both 3-meter and 12-meter bars. Telescopic arms accommodate both without wasted space.

• Plastic extrusion plants where dies and long parts vary weekly. Movable racks allow rapid layout changes.

• Aerospace component storage for fuselage stringers and wing spars that require dust-free, damage-free access. Electric extension minimizes manual handling.

• Automotive assembly lines feeding long chassis components. Movable racks can be repositioned as line layouts evolve.

Herochu’s Customization Options for Telescopic Movable Racks

No two warehouses are identical. Herochu offers:

• Variable upright heights from 2000 mm to 5000 mm.

• Arm length combinations: mix fixed and telescopic arms on the same upright.

• Extension method: manual (low cost) or electric with encoder feedback for precise positioning.

• Number of telescopic stages: two-stage (standard) or three-stage for very deep storage (up to 2500 mm extension).

• Mobility: rail-guided motorized carriages, forklift-moveable, or stationary with only telescopic adjustability.

Conclusion

The Adjustable Movable Storage Telescopic Cantilever Rack from Herochu represents a paradigm shift for warehouses that cannot tolerate fixed geometry. By combining extendable arms with repositionable bases, Herochu delivers a system that adapts to your inventory—not the other way around. With load capacities up to 2000 kg per arm, Q235B steel construction, and EU CE certification, these racks maintain heavy duty performance while adding unprecedented flexibility.
