High-Speed Gantry-Type Material Library | Herochu

In modern manufacturing and warehousing operations, efficient storage of long materials such as pipes, tubes, and profiles remains a persistent challenge. Traditional shelving systems often waste vertical space and require excessive manual intervention. The Herochu Gantry-Type Material Library redefines material handling by combining precision engineering with automated storage and retrieval technologies. Designed specifically for high-density vertical storage of pipes and similar elongated goods, this system achieves travel speeds of up to 50 m/min—double the industry average of approximately 25 m/min. This speed advantage translates directly into reduced cycle times and higher throughput for facilities handling steel tubes, aluminum extrusions, plastic pipes, or any long-form inventory.

Core Design Philosophy

Unlike conventional cantilever racks or floor-stacked storage, the Herochu Gantry-Type Material Library utilizes a floor-mounted rail system supporting a moving gantry crane. The shelves are arranged in independent towers, each capable of moving laterally to create a shared picking aisle. This “mobile shelf” concept eliminates the need for fixed aisles between every rack, dramatically increasing storage density. A typical warehouse layout can achieve up to 80% space utilization compared to less than 50% with static racks. The gantry itself is constructed using column gantry milling machine precision machining, ensuring structural rigidity and positioning accuracy to ±2 mm repeatability. External protective sheet metal not only safeguards internal components but also provides a clean, professional aesthetic aligned with modern factory safety standards.

Advanced Automation Components

The Herochu Gantry-Type Material Library integrates exclusively high-quality industrial components. The human-machine interface (HMI) is a Siemens touchscreen that displays real-time inventory data, storage location maps, and system diagnostics. Operators can execute automatic weighing of retrieved materials, manage load balance across multiple shelves, and perform library swapping (exchanging entire shelf modules) through intuitive on-screen menus. Omron sensors provide precise end-stop and positioning feedback, while Schneider Electric relays and circuit breakers ensure reliable power distribution. This component selection guarantees long service life and minimal downtime, even in dusty or high-temperature environments typical of metalworking shops.

Seamless Software Integration

A gantry-type material library is only as intelligent as its control software. Herochu supplies fully self-developed Warehouse Management System (WMS) and Warehouse Control System (WCS) with every installation. The WMS handles inventory tracking, lot management, first-in-first-out (FIFO) assignment, and generates usage statistics. The WCS translates those commands into motion sequences for the gantry, optimizing travel paths to avoid collisions and minimize energy consumption. Both systems can display live stock levels on large production screens, enabling shop floor personnel to check material availability at a glance. For facilities with existing ERP platforms, Herochu provides API connectors for bidirectional data exchange—no manual double entry required.

Enhanced Loading/Unloading Efficiency

One of the most time-consuming tasks in long material storage is aligning the load with the storage bin. The Herochu Gantry-Type Material Library incorporates an automatic centering function on the loading platform. When an operator places a bundle of pipes onto the platform, sensors detect the bundle’s lateral position, and hydraulic or motorized pushers center it automatically. This eliminates repeated manual hoisting adjustments, reduces the risk of dropped loads, and shortens loading/unloading time by up to 40%. Once centered, the gantry’s gripper engages the load and transports it to the designated shelf location. Retrieval follows the reverse process: the gantry fetches the material, deposits it on the unloading platform, and the centering system readies it for forklift or crane pickup.

Technical Parameter Overview

The Herochu Gantry-Type Material Library is available in multiple configurations to suit different pipe lengths and weight capacities. The model HC-X6053-8 handles materials up to 6,000 mm in length, with 5 storage layers (customizable to more or fewer), a maximum load per level of 3,000 kg, and 8 racks (customizable). Model HC-X7065-10 extends length to 7,000 mm, offers 6 layers, 5,000 kg per level, and 10 racks. The largest variant, HC-X8085-10, accommodates 8,000 mm pipes, 8 layers, 5,000 kg per level, and 10 racks. Gantry traveling speed is adjustable between 5 and 30 m/min, while lifting speed ranges from 5 to 15 m/min. The ±2 mm repeatability holds true across all models, ensuring that even fragile materials like thin-wall tubing are handled without deformation.

Operational Workflow in Real-World Scenarios

Consider a steel service center receiving 7-meter structural pipes daily. Incoming materials are first measured and weighed. The operator enters the pipe’s ID and dimensions into the Siemens HMI. The WMS automatically assigns an optimal storage location based on current occupancy and weight distribution across the gantry library. The gantry travels at 50 m/min to the receiving bay, picks the pipe using vacuum or mechanical grippers, lifts it, and moves laterally along the floor rails. Upon reaching the target shelf column, the gantry lowers the pipe into the bin. The entire storage cycle takes less than 90 seconds. When an order arrives, the operator selects the required pipe from the WMS interface; the gantry retrieves it, places it on the unloading platform with automatic centering, and updates the inventory instantly. Real-time dashboards show that the facility now stores 650 tons of pipe in a footprint that previously held only 320 tons.

Safety and Maintenance Features

Safety has been engineered into every motion axis. The gantry is equipped with laser distance sensors that detect personnel or obstructions in the travel path, triggering emergency stops before contact occurs. Limit switches on the lifting mechanism prevent over-travel beyond the topmost shelf. The external sheet metal protects operators from pinch points and falling debris. Routine maintenance is simplified through hinged access panels and color-coded wiring harnesses. Herochu recommends a quarterly inspection of the gantry rails, Omron sensor alignment, and lubrication of the traveling gearboxes. Mean time between failures (MTBF) for the Siemens and Schneider Electric components exceeds 50,000 operating hours.

Why Choose Herochu for Your Gantry-Type Material Library

Herochu has specialized in automated storage solutions for long goods for over a decade. Unlike generic automation integrators, Herochu engineers understand the unique behaviors of pipes—rolling, bending, nesting—and have designed gantry grippers and shelf geometries that accommodate both solid bars and hollow tubes. Every Gantry-Type Material Library is pre-assembled and tested at the Herochu factory before shipment, reducing on-site installation time to less than one week. Post-installation, Herochu provides remote troubleshooting via the WCS software, as well as on-site training for operators.
