Long goods storage is where conventional warehouse logic breaks down. A 12-meter steel pipe does not fit a pallet rack. A bundled stack of structural angles cannot be retrieved by a forklift without wide aisles and generous clearance. Herochu’s Gantry Automated Long Goods Storage System for Steel Profiles Pipes Warehouse is engineered around the specific geometry and weight distribution of long materials, not adapted from a system designed for pallets.
The architecture integrates four elements: multi-level long-goods racking, a rail-mounted gantry handling unit, material carriers, and WMS/WCS control software. The gantry travels along dedicated floor rails, performing horizontal positioning and vertical lifting without the sway that affects overhead bridge cranes when handling long, flexible loads. The material sits in carriers that present it consistently to the gantry, eliminating the variability that comes from stacked or leaning storage.
Herochu builds the racking to handle pipes, bars, tubes, and structural sections in loose or bundled form. The system accommodates lengths up to 12 meters in standard configurations, with customization for longer stock. Load ratings per level reach 3 to 5 tons, and the modular tower design allows 5 to 8 levels depending on ceiling height and inventory volume.
The control layer is where this system separates from a crane-and-rack arrangement. Herochu’s WMS handles inventory tracking, lot management, and FIFO assignment. The WCS translates retrieval commands into gantry motion sequences, optimizing travel paths to avoid collision and minimize cycle time. For a service center processing incoming pipe bundles and releasing them to cutting lines, this means the system knows which heat number is in which compartment and retrieves it in the sequence the production schedule requires.
Space efficiency is the headline benefit, but the mechanism matters. The gantry design eliminates the wide aisles that forklift access requires. Storage towers can be arranged back-to-back, with the gantry traveling the narrow corridor between them. Herochu reports up to 80% floor space savings compared to conventional floor storage. For a warehouse paying industrial lease rates, the recovered square footage often justifies the capital expenditure before labor savings are counted.
Safety is engineered into the motion logic. Laser sensors monitor the gantry path. Load monitoring prevents overload conditions. Omron sensors provide end-stop and positioning feedback, ensuring the gantry stops precisely where intended even under maximum load. These are not optional features; they are the baseline requirements for moving tons of steel overhead at speed.
The practical workflow looks like this: a truck arrives with bundled pipe. The overhead crane loads the bundle onto the infeed station. The gantry picks the bundle, identifies the storage location from the WMS, and places it in the assigned compartment. When the saw operator calls for that material, the gantry retrieves it and delivers it to the outfeed station. The operator never walks the rack aisle. The forklift never enters the storage zone. The inventory record updates without human data entry.
Herochu supplies this system with ERP and MES integration options, including API connectors for bidirectional data exchange. Facilities running SAP or similar platforms can push production orders directly to the storage system and receive material availability confirmation without manual reconciliation.
The Gantry Automated Long Goods Storage System is not a small-shop solution. It is capital equipment for operations moving significant tonnage of long stock and feeling the constraint of floor space and labor availability. For those operations, the calculation is straightforward: density, traceability, and safety, delivered through a single automated platform.
