Crank Type Pipe Rack with Adjustable Cantilever Arms – Herochu Heavy Duty Pipe Storage Rack

Standardization is a myth in industrial storage – every pipe diameter, every material length, and every facility layout demands a different approach. The Herochu Crank Type Pipe Rack addresses this reality by offering a modular, fully customizable Crank Out Cantilever Rack system that adapts to your specific inventory rather than forcing your inventory to adapt to a fixed rack design. Unlike competitive models that limit arm configurations or layer counts, Herochu provides an engineering-driven platform where every parameter – from arm depth to upright spacing – is specified by the customer.

At its core, the Hand Cranked Pipe Rack from Herochu operates on a simple but robust mechanical principle: a hand-cranked gearbox drives a rack-and-pinion or screw-driven mechanism that extends multiple cantilever arms simultaneously or in sequence, depending on the design. Single-side assisted movement means only one set of arms extends toward the aisle; double-side assisted allows arms on both sides of a central column to extend alternately or together. This flexibility is critical for facilities that store different material families on opposite sides of the same upright structure.

Load ratings for the Heavy duty Hand-cranked Crank-Out Rack are not guesswork. Each single-layer shelf supports between 3 and 8 tons, with the actual capacity determined by arm depth, arm spacing, and the number of uprights. Herochu publishes specific per-arm capacities based on extensive finite element analysis and physical testing: 20-inch arm depth – 6,600 lbs per arm; 24-inch – 5,600 lbs; 30-inch – 4,800 lbs; 36-inch – 4,200 lbs. These figures assume the load is evenly distributed across the arm’s length and does not exceed the arm’s tip height stop dimension.

The number of layers in a Crank Type Pipe Rack typically ranges from 4 to 12, but Herochu can engineer taller configurations for warehouses with high ceilings. What sets this design apart is the ability to independently adjust the vertical spacing between layers in one-inch increments. An operator can set the bottom layer at 24 inches clear height for large-diameter pipes, then reduce the next layer to 12 inches for smaller bars. This granularity maximizes storage density without sacrificing accessibility.

Material compatibility extends well beyond pipes and tubes. The Hand Cranked Tube Storage Racks also store aluminum profiles, bars, rods, shafts, channels, angles, beams, sheets, plates, rails, square tubes, round bars, and flat bars. For sheet and plate storage, optional roll-out shelves can be integrated, providing up to 100% extension for loading sheets onto a crane magnet or suction lifter. This makes the Herochu system a universal long-material storage solution rather than a single-purpose pipe rack.

One frequently overlooked feature is the bottom floor height of 330 mm from ground level. Many warehouse racks sit flush to the floor, which collects dust and debris and makes cleaning difficult. Herochu elevates the entire structure, allowing floor scrubbers to pass underneath and preventing moisture wicking from wet concrete. For facilities that occasionally use pallet jacks to move base materials, this clearance is essential.

Color customization is more than cosmetic. Herochu offers standard white and blue finishes, but custom colors can be specified to align with safety color codes (yellow for caution, red for fire equipment access, green for first aid stations) or to differentiate between production lines. Powder coating is standard, providing chip resistance and corrosion protection even in humid environments like shipyards or pipe coating plants.

The Heavy duty pipe storage Rack series from Herochu also addresses a common pain point: arm deflection under load. Some crank-out racks use thin-walled arms that sag, causing pipes to roll toward the center. Herochu arms are fabricated from structural-grade carbon steel with reinforced flanges. Even at full extension under maximum rated load, deflection remains under L/180, ensuring that pipes stay in place and the crank mechanism does not bind.

For operations handling extremely long materials – 30 to 40 feet – Herochu recommends specifying intermediate supports. These are steel bottom pieces that span between uprights, effectively reducing the unsupported length of the cantilever arms. With intermediate supports, a 40-foot pipe can be stored without bowing, and the crank-out mechanism still operates smoothly. Without intermediate supports, the maximum recommended length is 20 feet between uprights.

The Industrial Crank-Out Pipe Racks from Herochu are built to order with typical lead times quoted at the time of request. To order, customers provide: material type and dimensions, maximum bundle weight per layer, total number of distinct SKUs (to determine layer quantity), floor space available, and overhead crane or forklift specifications. Herochu then returns a 3D CAD model and engineering drawings for approval before fabrication begins. This consultative approach eliminates surprises during installation.

Additional accessories include stock dividers (all-welded for permanent separation or adjustable for reconfiguration), UHMW liners for scratch-sensitive materials, and extension limit switches for facilities that want a tactile or audible confirmation of full extension. The crank handle itself is ergonomically designed with a non-slip grip and can be positioned on either the left or right side of each upright per customer preference.

In operation, the Hand Cranked Pipe Racks and Storage Systems reduce retrieval time by as much as 70% compared to stacked floor storage. A worker simply approaches the rack, selects the desired layer, inserts the crank handle into the gearbox receiver, and turns. The arms advance steadily, bringing the stored pipes within easy reach of an overhead crane hook. After unloading, the worker reverses the crank to retract the arms, and locking pins automatically engage at the fully retracted position to prevent unintended extension. This cycle repeats thousands of times without significant wear, thanks to sealed bearings and hardened steel gears.

For heavy machinery plants, steel service centers, and aluminum extrusion facilities, the Herochu Crank Type Pipe Rack is not merely a storage product – it is a productivity tool. By eliminating the need for long-reach forklifts or labor-intensive manual pulling, it frees up equipment and personnel for value-added tasks.
