Industries that process or distribute long materials – steel profiles, aluminum extrusions, copper bars, plastic conduits, and composite sections – face a persistent storage challenge: how to organize diverse lengths and weights without dedicating enormous floor areas to static racks. Herochu’s telescopic cantilever long materials shelves provide the answer through a combination of cantilever strength, telescopic reach, and multi-layer vertical stacking. This system transforms chaotic material yards into orderly, high-density storage environments that integrate seamlessly with overhead cranes and transfer vehicles.

What Are Telescopic Cantilever Long Materials Shelves?

The name itself describes three essential characteristics. “Telescopic” refers to the movable arms that extend and retract horizontally, allowing variable reach. “Cantilever” describes the structural principle – arms supported at one end (the column) with no vertical supports at the free end, enabling unobstructed overhead access. “Long materials shelves” indicates the intended cargo: profiles, pipes, bars, tubes, and other items whose length significantly exceeds their cross-sectional dimensions.

Herochu constructs these shelves as integrated systems comprising multiple column pieces connected by stabilizing rods. Each column supports a series of fixed arms, with movable arms sliding within or over the fixed arms. Transmission rods run horizontally across all columns on the same shelf layer, linking the movable arms. At the control end, a sprocket chain drive (manual or electric) rotates the transmission rod, which converts rotational motion into linear movement through gear racks attached to the movable arms.

Structural Components in Detail

Column pieces – Vertical steel sections with pre-drilled holes for arm attachment and stabilizing rod connections. Column height determines the number of shelf layers (3, 4, or 5 layers standard, with custom heights available).

Fixed arms – Permanently attached to columns via bolted brackets. Fixed arms provide the outer channel or rail within which movable arms travel. They also contribute to overall rack rigidity.

Movable arms – Sliding elements that carry the stored long materials. Movable arms extend outward from the fixed arms, supported by linear bearings or low-friction wear pads. When retracted, movable arms nest inside or alongside fixed arms.

Stabilizing rods – Diagonal or horizontal cross-braces that connect adjacent columns, preventing sway and torsional deflection during extension and loading.

Transmission rods – Horizontal shafts that transfer rotational force from the drive end to all movable arms on a given layer. Precision-machined sprockets and chain drives ensure synchronization.

Control end kit – Manual crank assembly or electric motor with gearbox. Includes safety interlocks to prevent unintended extension and position indicators showing arm extension length.

Load Capacity and Material Handling

Each shelf side supports up to 5 tons of distributed load. For a typical 12-meter shelf layer with two sides (extending left and right from a central column row), total layer capacity reaches 10 tons. A 5-layer rack therefore handles up to 50 tons of long materials within a footprint of approximately 2.5 meters (width) by the retracted arm length plus aisle.

The gear rack transmission system provides smooth, controlled movement even under partial loads. Unlike chain-only systems that can jerk or bind, the gear rack maintains positive engagement throughout the extension stroke. Operators can stop at any intermediate position – useful when storing mixed lengths or when crane positioning requires partial extension.

Three-Dimensional Storage Logic

Traditional long material storage uses ground-level “bunks” – rows of concrete blocks or steel cradles that support pipes horizontally. Bunks consume massive floor areas, typically storing only one layer of material. Retrieval requires walking on top of stored pipes or using forklifts with long forks, both hazardous and inefficient.

Herochu telescopic cantilever long materials shelves replace bunks with vertical stacking. By elevating materials onto multiple shelf levels, the system achieves three-dimensional storage density. A facility that previously occupied 2,000 square meters for pipe storage can reduce that footprint to 600–800 square meters using 4- or 5-layer telescopic shelves. The freed space accommodates additional production equipment, assembly stations, or finished goods inventory.

The phrase “three-dimensional storage” as applied to these shelves means converting ground-level flat storage into stacked layers that utilize overhead height. Herochu’s engineering ensures that each layer remains independently accessible – the telescopic arms on level 4 extend without contacting materials on level 3, because the movable arms pass between fixed arm channels.

Applications Across Industries

Profile manufacturing – Aluminum extrusion plants store long finished profiles on telescopic shelves immediately downstream of the aging oven. The 5-ton capacity handles heavy architectural profiles, while the powder-coated surface prevents aluminum oxidation.

Steel bar storage – Reinforcement bar (rebar) suppliers organize different diameters and grades on separate shelf layers. The telescopic design allows a single overhead crane to serve multiple layers, reducing crane travel distance.

Copper tube warehousing – Plumbing and HVAC distributors store copper coils and straight lengths. The adjustable arm spacing prevents tube deformation, and the elevated storage keeps copper away from floor moisture.

Plastic profile extrusion – PVC window profiles and trim boards store efficiently on telescopic shelves. The smooth arm surfaces prevent scratching of finished surfaces.

Integration with Profile Transfer Vehicles

Herochu offers profile transfer vehicles as complementary equipment for telescopic cantilever shelves. These motorized carts serve two critical functions:

Long-distance transfer – Moving profiles from receiving docks to storage bays without using overhead cranes. The transfer vehicle’s elevated deck aligns with shelf arm height, allowing direct roll-on/roll-off transfer. This solves the problem of long-distance transfer requiring vehicle hoisting and the associated safety risks.

Line-side storage – During unloading or processing operations, the transfer vehicle acts as temporary storage. Materials remain elevated, reducing labor intensity for personnel who would otherwise bend to ground level for picking.

The transfer vehicle works in both crane-served and crane-free areas. For storage zones without overhead crane coverage, the vehicle shuttles materials to a crane-served transfer point, where a crane then places materials onto telescopic shelves. This hybrid approach minimizes crane infrastructure investment while maintaining full storage accessibility.

Supporting Crane Systems for Complete Solutions

Some facilities lack any crane coverage in their profile storage area. Herochu addresses this gap with supporting crane systems – gantry or jib cranes designed specifically for long material handling. These cranes integrate directly with the telescopic cantilever shelves, sharing control systems and safety interlocks.

The crane system, profile transfer vehicle, and telescopic shelves form a complete material flow solution. Incoming materials move from truck to transfer vehicle to crane to shelf. Outgoing materials reverse the flow. All equipment shares a common design language and maintenance protocol, simplifying operator training and spare parts inventory.

Customization and Engineering Support

Herochu does not offer generic telescopic cantilever long materials shelves. Each installation begins with a site assessment: measuring available floor space, ceiling height, crane capacity (existing or planned), typical material lengths and weights, throughput requirements, and budget constraints.

Based on this assessment, Herochu engineers specify:

• Number of shelf layers (3, 4, 5, or more for very high ceilings)

• Layer length (6m, 9m, 12m, or custom intermediate lengths)

• Drive configuration (manual or electric, with optional remote control)

• Color coding for visual management or branding

• Stabilizing rod patterns for seismic or high-wind regions

The engineering team produces structural calculations, foundation drawings, and installation sequences. Herochu’s self-operated factory then fabricates all components, applies powder coating, and ships to site. Installation services complete the one-stop solution.

Long-Term Durability and Maintenance

Herochu telescopic cantilever shelves are built for decades of service. The steel structure carries a structural warranty. Powder coating resists chipping, fading, and corrosion in indoor or covered outdoor environments. Wear pads and linear bearings are replaceable without disassembling the entire rack.

Preventive maintenance includes annual inspection of chain tension, gear rack lubrication, and bolt torque checks. Herochu provides maintenance manuals and remote troubleshooting support. For electric drive systems, motors and gearboxes use standard industrial components available from local suppliers.
