90度回転するカンチレバー

Is 60% of your warehouse floor just empty space for forklift turning circles? Handling 20-foot long pipes, aluminum extrusions, or timber shouldn’t mean sacrificing the majority of your valuable footprint to excessively wide aisles. The constant risk of material damage and slow, multi-step retrieval processes are capping your operational throughput.

The Daily Problem: Why Traditional Long Goods Storage is a Losing Battle

In any facility handling long materials—be it a building materials distributor, a furniture manufacturer, or an aluminum profile plant—the operational workflow is dictated by the limitations of the side-loader forklift. To handle a 20-foot (approx. 6m) bundle of steel tubing, the forklift requires a turning aisle of at least 16 feet (approx. 5m). This creates a massive, unavoidable waste of space.

This leads to the classic “honeycomb effect” in your inventory. To access a specific bundle of material, operators often have to move three or four other bundles out of the way first. This multi-step process is not just slow; every extra handling action increases the risk of scratching, denting, or bending high-value stock. For a plant manager, this translates directly into lost time, damaged inventory, and operational bottlenecks that throttle the entire production or distribution chain.

The 90-Degree Shift: Engineering a Solution to the Tyranny of Turning Radius

The core innovation of the starack-Long Cantilever AS/RS system is that it fundamentally separates the action of “transport” from the action of “storage.” It eliminates the need for a vehicle to turn within the storage area by introducing a specialized interface and a dedicated retrieval machine.

Step 1: The Interface – The 90-Degree Rotating Conveyor

Instead of a forklift driving into the aisle, long goods are delivered to the head of the storage aisle via a simple roller conveyor. The key component is the integrated 90-degree rotating mechanism. A 20-foot bundle of PVC pipe arrives lengthwise, is automatically rotated a full 90 degrees, and is then perfectly positioned for sideways pickup. This single, automated motion completely solves the turning radius problem before the material even enters the high-density storage zone.

Step 2: The Core – The Cantilever Stacker Crane

Once the material is positioned sideways, a dedicated Stacker Crane takes over. Running on a precise floor and ceiling rail system (Bottom Rail and Top Rail), this crane only needs an aisle slightly wider than itself—often as narrow as 5 feet (1.5m). Constructed from Q355 high-strength steel, the crane mast has the rigidity to lift multi-ton loads to heights of 40 meters or more without sway or oscillation. Using a laser positioning system, it achieves a stop accuracy of ±3mm, gently placing the long bundle onto the cantilever arms without impact. This entire process is orchestrated by the Warehouse Management System (WMS), ensuring the right material is stored or retrieved in seconds.

From Wasted Aisles to Value-Generating Density: The Tangible ROI

By implementing a starack-Long system with a 90-degree turn interface, you are not just buying a machine; you are fundamentally changing the economics of your warehouse footprint. The shift from a forklift-dependent layout to an automated narrow-aisle system delivers quantifiable improvements across every key metric.

Ultimately, the starack-Long system transforms long goods storage from a space-intensive, manual liability into a compact, automated, and highly efficient asset. It allows manufacturers and distributors to reclaim their floor space, protect their inventory, and meet production deadlines with unprecedented speed and reliability.
