Long pipes, tubes, and structural profiles occupy a disproportionate amount of warehouse floor space when stored conventionally. Flat horizontal storage spreads material across the available ground area, consumes aisles for forklift access, and still leaves the inventory untraceable in real time. The Top-Mounted Profile Vertical Storage ASRS System from Herochu was designed to resolve all three problems through an overhead retrieval architecture that stores long materials vertically and handles them automatically.

This article details how the top-mounted design works, what it delivers operationally, and where it fits in modern manufacturing facilities handling heavy long-format inventory.

The Overhead Retrieval Concept

The defining feature of this system is its top-mounted lifting platform. Instead of a floor-level forklift or a ground-running gantry, the retrieval mechanism is an overhead traveling car mounted on guide rails that span the full length of the rack structure. The lifting platform hangs from this overhead car, descending to the target storage layer to extract or deposit a bundle of pipes or profiles.

This top-mounted configuration is a structural decision with real operational consequences. By placing the retrieval mechanism above the storage racks, the system frees the ground level entirely for material flow, walkway clearance, and integration with downstream production equipment. There is no gantry frame occupying floor space, no rail mounted at ground level that crosses walkways, and no forklift aisle required for retrieval.

The result is a storage system that consumes vertical space efficiently while leaving the floor open for production operations. For facilities where ground-level clearance is needed for material transport, pedestrian safety, or equipment placement, the top-mounted architecture is the configuration that fits.

Vertical Storage for Materials Up to 12000 mm

The rack structure is engineered to store pipes, tubes, and profiles up to 12000 mm in length. That capacity covers the longest standard sections used in structural fabrication, including extended steel pipe bundles, long aluminum extrusions, and heavy structural alloy bars.

Each long material bundle is placed into a dedicated horizontal storage slot. The vertical multi-level design stacks these slots into a tower configuration, turning scattered long stock into an organized storage center that maximizes the use of available workshop vertical space. Compared with flat horizontal storage, where material length directly determines floor consumption, the vertical design decouples storage capacity from ground footprint.

For facilities handling long materials, this is the primary value proposition. A 12-meter bundle of steel pipe stored horizontally demands 12 linear meters of floor space per row. Stored vertically in the Top-Mounted Profile Vertical Storage ASRS from Herochu, that same bundle occupies a fraction of that footprint, stacked among layers that each hold their own inventory.

Technical Performance Specifications

The system is rated for industrial-scale workloads. Each storage layer supports a load capacity of up to 5000 kg, safely handling heavy bundles of round pipes, square tubes, and rectangular structural profiles. That per-layer rating ensures the system can accommodate concentrated bundle weights without structural concern.

Performance parameters include:

• Maximum material length: Up to 12000 mm
• Layer load capacity: Up to 5000 kg per storage layer
• Hoist lifting speed: 40 m/min
• Overhead car translation speed: 100 m/min
• Positioning accuracy: ±2 mm repeat accuracy
• Control system: PLC with touch screen interface, one-key operation
• Slot configuration: Flexible planning by diameter, shape, and bundle type

The hoist lifting speed of 40 m/min and the overhead car translation speed of 100 m/min combine to deliver storage and retrieval cycles that keep pace with continuous daily operation. Whether the system is feeding a laser cutting cell, an automated saw line, or a structural welding station, the retrieval speed ensures material delivery does not become the bottleneck.

The ±2 mm repeat positioning accuracy is maintained across all cycles. That consistency is what allows the system to interface directly with automated downstream equipment, where a specific bundle must arrive at a specific position to be picked up by the next machine in the line.

PLC Touch Screen Control and One-Key Operation

The system is operated through a PLC touch screen interface that handles both the retrieval mechanics and the inventory database. Warehouse staff select a storage slot from the interface, and the system executes the full retrieval cycle automatically: the overhead car travels to the correct rack position, the lifting platform descends to the target layer, the bundle is extracted, and the material is delivered to the load-out point.

That one-key operation reduces the manual handling of long and heavy items to near zero. In conventional storage, retrieving a 12-meter bundle of steel pipe requires a forklift, an operator, and a clear aisle path. In the Top-Mounted Profile Vertical Storage ASRS from Herochu, it requires a screen selection and a confirmed cycle start.

The control system also maintains the live inventory database. Every storage and retrieval transaction updates the digital record, giving warehouse teams an accurate, real-time view of stored material by slot, type, and quantity. That data eliminates manual stock counting and supports production planning with dependable stock figures.

Multi-Size Flexible Slot Planning

Manufacturing facilities rarely store a single material type. The same warehouse may hold round steel pipe, square structural tubing, rectangular aluminum profiles, and alloy bars across a range of diameters and cross-sections. The Top-Mounted Profile Vertical Storage ASRS from Herochu handles this diversity through flexible slot planning.

Storage slots adapt to different pipe diameters, tube sizes, and profile shapes. The slot layout can be planned based on actual on-site materials and adjusted as the production mix changes. A facility that shifts from a predominantly steel round pipe inventory to a higher proportion of square structural tubes does not need to re-engineer the rack. It redefines the slot configuration in the control system and adjusts the physical dividers to match.

That flexibility protects the capital investment. The rack adapts to the inventory rather than forcing the inventory to conform to a fixed storage geometry.

Space Saving and Workshop Layout Integration

The vertical multi-level design delivers a floor space reduction that directly improves workshop layout. Compared with flat horizontal storage of long materials, the vertical configuration frees ground space for processing machines, widens walkways for worker and forklift safety, and creates room for the material handling flow that production demands.

The space recovered is not incidental. Facilities that have moved from horizontal pipe storage to vertical automated systems routinely report reclaiming a majority of the floor area previously dedicated to long material storage. That space becomes productive capacity: room for an additional cutting machine, a wider assembly lane, or simply the clearance needed to meet safety compliance standards.

Because the retrieval mechanism is overhead, the ground level remains clear of fixed obstructions. That clearance supports forklift traffic for short materials, pedestrian movement, and the integration of the storage system with adjacent production equipment without structural conflict.

Digital Inventory Management for Production Planning

The PLC-based digital inventory system does more than track what is in the rack. It supports efficient production planning by providing accurate, real-time stock data. When production scheduling depends on knowing exactly how many bundles of a specific pipe diameter are available, the system delivers that figure instantly without a manual count.

That data accuracy reduces the safety stock buffer that facilities maintain to protect against inventory uncertainty. When the stock record is reliable, procurement can order against actual need rather than inflated estimates, freeing working capital tied up in excess material.

For warehouse teams, the digital inventory display also streamlines stock counting. Instead of walking the racks with a clipboard, the full inventory is available on the PLC interface, updated with every transaction.

Application Scope

The Top-Mounted Profile Vertical Storage ASRS System from Herochu is engineered for facilities where long-format material storage and retrieval define daily warehouse operations:

• Steel service centers managing bundled round, square, and rectangular pipe inventory
• Structural fabrication shops handling long sections for cutting and welding
• Aluminum profile distributors storing mixed extrusion types and lengths
• Laser cutting facilities requiring timed material delivery to cutting cells
• Manufacturing plants integrating vertical storage with automated production lines

For operations where floor space is constrained, long materials dominate the inventory, and manual retrieval is a daily bottleneck, the top-mounted vertical storage architecture delivers a measurable operational improvement.

Conclusion
