Save warehouse space with movable shelves

In high-stakes automotive assembly, static storage is a bottleneck. Fixed aisles for forklifts consume 40% of your floor space, while “dead” inventory accumulates in hard-to-reach corners. To hit aggressive cycle times and enable true JIT (Just-In-Time) delivery, you need to convert static buffers into dynamic, Mobile Flow Racks for SPS. It’s time to decouple your logistics from fixed infrastructure.

The “Wide Aisle” Trap in Automotive Manufacturing

Traditionally, supplying parts to the trim or chassis line required wide aisles (often 3.5 to 4 meters) to accommodate the turning radius of manned forklifts. This layout forces you to space out your inventory, increasing the travel time for pickers and reducing the density of SKUs available at the Line-side Supply point.

Furthermore, static racks often lead to “buried” inventory. In a fast-paced environment handling powertrain components or stamped chassis parts, the inability to move the rack means that once dunnage is placed, it stays there until manually cleared. This rigidity prevents the implementation of flexible “supermarkets” needed for mixed-model production lines.

Engineering Rigidity for Dynamic Loads

Transitioning to movable shelves requires more than just adding wheels. When a Underride AGV lifts a rack loaded with 800kg of transmission parts, the frame endures significant torsion and upward lift forces—stresses that standard static shelving was never designed to handle.

At SpaceDAS, we utilize a Fully Bolted Structure using Q355 High-tensile Steel. Unlike welded racks which can develop fatigue cracks under constant vibration, or hook-and-slot racks that can detach when lifted, our bolted connections with anti-loosening nuts ensure the rack acts as a single rigid body. This prevents the catastrophic failure of dropping a battery module or engine block during transit.

Karakuri Integration: The “Shooter” Mechanism

To truly save space and remove human intervention, we integrate Karakuri (low-cost automation) mechanics. By equipping the movable shelf with gravity flow rails and a mechanical shooter system, the AGV can dock at the workstation, mechanically trigger a release lever, and “shoot” the KLT boxes or blister trays directly onto the assembly line conveyor.

This mechanism allows for “One-Touch” logistics. Empty dunnage is automatically returned to the lower level of the rack, and the AGV departs. This cycle reduces the line-side footprint by up to 60% compared to static pallet drop-off zones.

Comparative Analysis: Static vs. Mobile Flow

The table below outlines the operational shift when moving from static racking to a Automated KLT Box Rack system in a typical automotive assembly hall.

Feature	Традиционная статическая ракетка	SpaceDAS Mobile Flow Rack
Aisle Width Req.	3.5m – 4.0m (Forklift)	1.0m – 1.2m (AGV/AMR path)
Structure Type	Welded or Hook-and-Slot	Fully Bolted Q355 Anti-loosening
Inventory Flow	LIFO (prone to obsolescence)	Strict FIFO via Gravity Flow
Space Utilization	Low (Fixed dead zones)	High (Dynamic Line-side Delivery)

Frequently Asked Questions (Automotive Logistics)

1. Can these racks handle heavy EV battery modules?

- да. - да.для Комплект аккумуляторов EV transport, we utilize reinforced Q355 steel frames designed to handle dynamic loads exceeding 1,000kg, with specific center-of-gravity calculations to prevent tipping during AGV acceleration.

2. How does the rack connect with the AGV?

Our racks feature a laser-cut interface and a QR code calibration matte on the underside. This allows Underride AGVs (like Hikrobot or Geek+) to position themselves with millimeter precision before lifting.

3. Will vibration loosen the rack structure over time?

No. Unlike welded racks that crack under fatigue or hook racks that shake loose, we use a fully bolted structure with serrated lock nuts (Anti-loosening design), specifically engineered for the high-frequency vibrations of mobile robotics.

4. Is the flow rack compatible with standard KLT boxes?

Absolutely. The roller tracks and guide rails are adjustable to fit standard VDA KLT boxes, plastic blister trays, or custom dunnage used in the automotive supply chain.

5. Do you support “Set Parts Supply” (SPS) operations?

Yes. Our mobile racks are ideal for SPS zones, allowing kit carts to be prepared in the warehouse and autonomously transported to the assembly line, replacing manual tugger trains.
