Pipe and tube storage is notoriously difficult. Round profiles roll off flat surfaces. Long lengths require wide aisles for access. And traditional cantilever racks with fixed arms force warehouses to dedicate entire bays to a single pipe diameter. Herochu solves these problems with the heavy-duty cantilever racking storage rack equipped with an electric telescopic pipe cantilever – a specialized arm design that combines a V-shaped saddle, powered extension, and pipe-specific safety features.

Why Pipe Needs a Specialized Cantilever Arm

Standard cantilever arms have flat or slightly inclined top surfaces. When storing pipes, these flat surfaces allow pipes to roll sideways unless restrained by dividers or rubber mats. Worse, when an operator retracts a telescopic arm with pipes on it, the pipes can shift and fall between arm sections. Herochu’s pipe cantilever uses a formed steel saddle with a 120-degree included angle, lined with replaceable polyurethane pads. The saddle prevents rolling and centers the pipe automatically. For bundles of small-diameter pipes (e.g., conduit), the saddle can be fitted with removable dividers that create individual channels.

The telescopic function is critical for pipe because pipe lengths vary widely. A single rack might store 6-meter pipes on the bottom level and 2-meter offcuts on the top level. With fixed arms, the top-level arms would extend uselessly into the aisle. With Herochu’s electric telescopic pipe cantilever, each arm retracts independently, matching its projection to the actual pipe length stored.

Electric Telescopic Mechanism for Pipe Loads

Pipes present a unique challenge to telescopic mechanisms: they are round and can rotate. If a pipe rotates during arm extension or retraction, it can bind against the saddle or fall off. Herochu addresses this by using a slow-speed, high-torque electric drive. The extension speed is limited to 30 mm per second (compared to 100 mm per second for general-purpose arms). This gives any pipe movement time to settle. Additionally, the saddle includes a spring-loaded detent at the rear – a small raised bump that pipes must roll over to exit the back of the arm. This detent acts as a passive brake.

The telescopic sections themselves are made from seamless round tubing rather than square tubing for pipe cantilevers. Round sections have no corners that could catch a pipe’s edge. The outer tube is 114 mm diameter with 8 mm wall thickness; the inner tube is 89 mm diameter. A nylon bushing between them eliminates metal-on-metal contact. The extension is driven by a ball screw inside the inner tube, protected by a flexible rubber bellows. The ball screw provides smooth, precise motion and is self-locking, so the arm holds position without a separate brake.

Structural Design of Heavy-Duty Cantilever Racking for Pipe Storage

Pipe bundles are heavy. A typical bundle of 6-meter Schedule 40 steel pipe (2-inch nominal diameter) weighs approximately 500 kg. Herochu’s heavy-duty cantilever racking storage racks are built to handle multiple such bundles per level. The upright frames are double C-channel sections back-to-back, welded to a base plate. Each upright has a capacity of 10,000 kg total distributed load. The cantilever arms attach to the uprights using four M20 bolts per arm – not the common pin-and-hole method – because the vibration from loading pipes can loosen pins over time.

The base is critical. Herochu uses a full-width base beam rather than separate footplates. This beam spans the entire width of the rack (typically 1200 mm to 2200 mm) and is made from 250 mm H-beam. It distributes the load across multiple floor anchors, preventing point loading that could crack concrete. For outdoor pipe yards, the base is hot-dip galvanized after welding, with drain holes to prevent water accumulation.

Cross braces between uprights are tubular steel with flattened ends, bolted rather than welded. This allows the rack to be disassembled and moved. For racks taller than 3 meters, Herochu adds horizontal sway braces at each level, creating a rigid box structure.

Electric Control System for Pipe Handling

The electric telescopic pipe cantilever uses a wired remote with an analog joystick rather than push buttons. The joystick gives variable speed control – the further the operator pushes, the faster the arm moves. This is essential for pipe because the operator may need to creep the arm forward to align a pipe with an overhead crane hook. The remote also has a dedicated “pipe unload” mode: when activated, the arm extends 50 mm, pauses, then continues. The initial 50 mm jostle helps settle pipes that have shifted during storage.

For warehouses with multiple pipe diameters, Herochu offers an auto-sensing option. A laser distance sensor on the arm measures the actual pipe length after loading. The system then stores that length in memory and automatically retracts the arm to the minimum projection needed for that bundle. On subsequent retrievals, the arm extends only to that length, saving time and space.

Application: Pipe Distributor Case Study

A Midwest pipe distributor storing 10,000 tons of carbon steel pipe in lengths from 1.5 to 12 meters replaced their floor storage with 20 Herochu heavy-duty cantilever racking storage racks, each with 4 levels of electric telescopic pipe cantilevers. Before the upgrade, retrieving a specific pipe required moving other pipes with a forklift, causing damage and taking an average of 15 minutes. After installation, a single operator uses a remote to extend the correct arm, the overhead crane lifts the pipe bundle, and the arm retracts. Average retrieval time: 1.5 minutes. The distributor reported a 40% increase in throughput and a 90% reduction in pipe surface damage.

The telescopic feature also enabled them to store offcuts efficiently. Previously, cut pieces shorter than 3 meters were thrown into scrap bins because they were too short for the fixed-arm racks. With Herochu’s retractable arms, they now store offcuts on the top levels with arms retracted to match the shorter lengths, recovering material value.

Specifications and Customization

All Herochu heavy-duty cantilever racking storage racks come with SGS and ISO certification. The powder coating process includes a two-stage pickling treatment that creates an oxidation film for superior adhesion – a method Herochu says no other manufacturer matches. Lead time is 20 days for custom orders.

Safety and Maintenance

Pipe storage racks require regular inspection of the polyurethane saddle liners. Herochu designs them to be replaceable without removing the arm from the rack – simply unbolt a retaining plate and slide the old liner out. The ball screw drive should be greased every 6 months via a built-in zerk fitting. The electric motor has a thermal protection switch that automatically resets when cooled.

For facilities subject to seismic activity, Herochu offers base isolation pads that allow the rack to sway up to 50 mm without tipping. This is especially important for pipe racks, which have a high center of gravity when fully loaded.

Conclusion

The heavy-duty cantilever racking storage rack with electric telescopic pipe cantilever is not a generic product adapted for pipe – it is a purpose-engineered system where every detail, from the V-saddle to the ball screw drive, addresses the unique challenges of tubular products. Herochu delivers this system with full customization, short lead times, and certifications that assure quality and safety. For pipe distributors, fabrication shops, and construction material suppliers, this rack transforms a problematic storage category into a competitive advantage.
