Telescopic Cantilever Shelving for Pipe Storage with Overhead Crane Integration

Pipe storage presents a unique material handling problem. Pipes are long, heavy, prone to rolling, and difficult to stack without damage. Fixed cantilever racks improve organization but still require wide aisles for access. Herochu has developed telescopic cantilever shelving for pipe storage that solves the aisle-width problem while maintaining full crane compatibility. This system allows individual arms to extend out from the column face—typically by 100% of their retracted length—creating a temporary loading platform directly under an overhead bridge crane. After loading, the arms retract, pulling the pipes into a compact, stable storage position.

The operating sequence defines the value of telescopic cantilever shelving for pipe storage. First, the operator turns a manual winch connected to the selected arm level. The arm slides outward on precision guides until it reaches its fully deployed position. Next, an overhead crane moves a bundle of pipes directly above the extended arm. The crane lowers the pipes onto the arm, which has been designed with a slight upward tilt or pipe-retention features to prevent rolling. After the crane disengages, the operator reverses the winch, and the arm retracts, bringing the pipes flush against the upright column frame. The entire process takes less than two minutes per arm level.

Herochu constructs each unit with a focus on stability during the extension and retraction cycle. The upright column frame uses welded square tubing with internal guides that maintain arm alignment under eccentric loads. When the arm extends fully with a 1000 kg pipe bundle, the moment force on the column increases significantly. Herochu counters this by specifying base lengths proportional to arm extension. For a 1000 mm deployed arm length, the base length must be at least 1800 mm. Adjustable diagonal flats connect multiple column frames together, distributing the overturning force across the entire row.

Load capacity for Herochu telescopic cantilever shelving for pipe storage is rated at 600–1000 kg per arm. This rating applies to both the extended and retracted positions. However, dynamic loads during extension require additional safety margin. Herochu uses GB-T Q345 steel for all load-bearing arm components, with 45# carbon steel for the winch drum and gear train. The winch mechanism includes a self-locking brake that prevents uncontrolled retraction if the operator releases the handle. For heavier pipe applications, Herochu offers an electric motor option, though the manual winch remains the most common choice for its simplicity and reliability.

Space utilization improves dramatically compared to static cantilever racks. Standard fixed-arm shelving requires aisle widths of at least twice the arm length to allow crane access. For a 1000 mm arm, that means a 2000 mm aisle. Herochu telescopic cantilever shelving for pipe storage reduces the required aisle width to just the retracted arm length plus clearance for the crane hook, typically 1200 mm total. Over a 100-meter-long rack row, this difference saves 80 square meters of floor space. That space can house additional rack rows, increasing total storage density by 60% or more according to Herochu field measurements.

Customization options abound. Arm lengths range from 500 mm to 1000 mm as standard, but Herochu can extend arms up to 3000 mm for oversized pipe diameters. The number of layers per column ranges from two to seven, with story heights adjustable between 440 mm and 940 mm. Active height between arms varies from 250 mm to 800 mm, accommodating pipe diameters from small tubing to large-diameter steel pipe. Column height can exceed 6.5 meters for facilities with high ceilings. Base lengths customize from 1200 mm to 2200 mm, with longer bases required for taller or heavier configurations.

Safety features extend beyond the winch brake. The telescopic cantilever shelving for pipe storage from Herochu includes end stops that prevent arm over-extension. Guide rollers are sealed and greased to prevent jamming from pipe scale or dust. Each arm level operates independently, allowing mixed-height pipe storage on the same column. For example, a facility might store 200 mm diameter pipes on the bottom level with 600 mm active height, 100 mm pipes on the middle level with 400 mm active height, and 50 mm tubing on the top level with 250 mm active height. This flexibility is impossible with fixed-arm systems.

Installation and support from Herochu includes detailed installation drawings and optional on-site instruction. For complex layouts involving multiple rows and crane interference zones, Herochu design services create a full 3D layout. Free samples of the telescopic arm mechanism are available, allowing potential buyers to test fit and operation before committing to a full purchase. OEM customization is offered for special pipe diameters, unusual building geometries, or integration with existing conveyor systems. Backup services include spare parts availability and remote troubleshooting.

For pipe storage yards currently using floor stacking or simple pallet racks, the upgrade to Herochu telescopic cantilever shelving for pipe storage delivers immediate benefits. Floor stacking damages pipes through crushing and scratching. Simple pallet racks lack the length support needed for long pipes, leading to sagging and bending. Herochu shelving supports pipes along their full length (or at multiple points) and keeps them separated by arm level, eliminating contact damage. The retractable arms also reduce the risk of crane-to-rack collisions because the crane never needs to enter the storage footprint.

In high-throughput facilities, the time savings from telescopic access add up. A pipe retrieval that takes five minutes from a static rack (including maneuvering the crane) takes two minutes from a Herochu telescopic system. Over 50 retrievals per day, that saves 150 minutes of crane time, directly improving throughput. For any facility handling long pipes with overhead cranes, Herochu telescopic cantilever shelving for pipe storage offers a proven, durable, and highly space-efficient storage solution.
