Pipes and tubes present distinct handling challenges compared to solid profiles. Their hollow cross-sections make them susceptible to denting if not properly supported. Their length-to-diameter ratio causes them to roll or shift during movement. Traditional storage methods—stacking on flat floors or leaning against racks—lead to damaged ends, bent sections, and inefficient use of space. Herochu introduces the Intelligent Mobile Long Pipe Material Library, a dedicated system designed from the ground up for pipe and tube storage. This article details the engineering features, operational benefits, and technical specifications of Herochu’s solution for long pipe materials.

System Design for Long Pipe Constraints

The Herochu Intelligent Mobile Long Pipe Material Library consists of a loading and unloading gantry system, profile material racks, material frames, and guide rails. While the general architecture resembles other Herochu systems, the specific design choices for pipes and tubes differ in critical ways. The profile material racks incorporate saddles or V-rests that cradle the pipe circumference, preventing rolling. The material frames separate individual pipes or bundles to avoid contact marks. The guide rails and gantry system are sized for the typical lengths found in pipe storage—6 meters, 9 meters, or 12 meters—with allowances for longer industrial tubing.

The main structure has a high load-bearing capacity, is sturdy and durable, and can store single or bundled pipes of different diameters and wall thicknesses. The number of layers and quantity of racks are customized according to the factory’s clear height and the specific pipe dimensions. For pipe storage, layer spacing must account for the possibility of stacked bundles, which can increase the effective load per layer.

Technical Specifications for Pipe Handling

Herochu provides clear parameters for the Intelligent Mobile Long Pipe Material Library. Main structure widths: 6015 mm, 6020 mm, or 6025 mm. Number of floors: 8 to 13. Load per layer: 3 tonnes or 5 tonnes. Mode of movement: linear guide rail combined with chain. Transmission mode: chain drive. Vertical lifting speed: 9 meters per minute. Inlet and outlet horizontal speed: 12 meters per minute. Profile support: optional selection, with pipe-specific options including V-rests, adjustable cradles, or custom-formed saddles.

The moderate speeds are particularly important for pipes. A bundle of round pipes placed on a flat support can roll if acceleration or deceleration forces exceed the friction holding them in place. Herochu’s 9 m/min vertical lift and 12 m/min horizontal movement maintain low acceleration rates, preserving bundle stability. The chain drive provides smooth, jerk-free motion, further reducing the risk of pipe displacement.

Addressing Spatial Inefficiency in Pipe Storage

The fundamental value proposition of the Herochu system lies in its radical approach to spatial efficiency. In standard warehousing, a significant percentage of the total volume is sacrificed to access aisles and safety margins required for forklifts and bridge cranes to maneuver. These “flue spaces” are non-revenue generating areas that nonetheless consume expensive square footage. Herochu challenges this inefficiency by utilizing a high-density vertical configuration that transforms the warehouse structure itself into the storage medium. By employing a sophisticated gantry-based retrieval system, the need for wide external access lanes is eliminated. The result is a staggering capacity density: a single Herochu installation can house up to 500 tonnes of mixed pipe diameters and lengths within a compact footprint of approximately 200 square meters. For facility managers weighing the capital expenditure of a building expansion against the optimization of current assets, this system offers a compelling, cost-effective alternative to construction.

This density is achieved through a footprint-optimized design that assumes standard pipe lengths, typically around 12 meters, and utilizes verticality to its fullest extent. With configurations supporting up to 13 storage levels, Herochu effectively doubles or triples the storage density per square meter compared to standard cantilever racks or floor stacking. For a pipe distributor with high inventory turns, this density translates directly into lower rent per tonne stored.

Precision Gantry for Long Pipe Retrieval

High-density pipe storage is only viable if the retrieval mechanism is precise. At the heart of the Herochu Intelligent Mobile Long Pipe Material Library lies the loading and unloading gantry robot. Unlike standard overhead cranes that may induce load swing or require excessive safety zones, the Herochu gantry operates on precision linear guide rails. This design choice is critical for handling long, flexible pipes that can sag or whip if unsupported. The linear guide rails ensure that the gantry moves parallel to the pipe axis, maintaining consistent support along the entire length.

The transmission mode of the gantry utilizes a robust chain drive, a component selected specifically for its durability and ability to handle high torque at low speeds. While the operational speeds—9 meters per minute for vertical lifting and 12 meters per minute for horizontal inlet/outlet—may appear moderate when compared to high-speed parcel sorters, they are calculated specifically for the physics of heavy industrial loads. Moving 3 to 5 tonnes of pipe per layer requires stability over velocity. The moderate speed prevents load sway, ensuring that a bundle of tubes does not shift or slide during the pick-and-place cycle. For pipes, even a small shift can cause the bundle to become unbalanced, leading to dropped loads. Herochu’s speed profile eliminates this risk.

Pipe-Specific Handling Features

Beyond the base specifications, Herochu offers several options tailored to long pipe storage. First, the profile supports can be equipped with polyurethane padding to prevent coating damage on finished pipes. Second, the gantry’s gripping mechanism can be configured as a fork-type or clamp-type depending on whether pipes are stored individually or in bundles. Third, the system can include length sensing to verify that the retrieved pipe matches the requested length before releasing it to the unloading station. Fourth, for pipe mills producing continuous lengths, the Herochu system can interface with cut-to-length lines, automatically storing finished cut pipes without manual intervention.

Operational Workflow for Pipe Storage

A typical operation cycle begins when a forklift or conveyor delivers a bundle of pipes to the loading station. The Herochu gantry system measures the bundle dimensions and weight, then selects an available storage location. The gantry lifts the bundle, travels along the guide rails to the correct column, raises or lowers to the designated level, and deposits the bundle onto the profile material racks. The reverse cycle occurs for retrieval. The entire process is managed by the Herochu control system, which maintains a real-time map of every stored pipe bundle. For pipe distributors filling customer orders, the system can sequence retrievals to assemble complete orders without re-handling.

Conclusion

The Herochu Intelligent Mobile Long Pipe Material Library addresses the specific challenges of pipe and tube storage through high-density vertical configuration, precision gantry movement on linear rails, chain drive transmission, and selectable pipe supports. With capacity up to 500 tonnes in a 200-square-meter footprint and retrieval rates of 15 to 20 picks per hour, Herochu delivers a system that reduces floor space requirements, improves inventory accuracy, and protects pipe quality. For any operation handling long pipes—steel tubing, copper pipe, PVC conduit, or stainless tube—the Herochu library offers a dedicated, high-performance storage solution.
