Easy to assemble mobile racks for AGVs

The Engineering Logic: Why “Bolted” Beats “Welded” in Automotive Logistics

In traditional automotive stamping or powertrain plants, the standard used to be welded pallet racks. They were sturdy, but they were permanent. Today, with the shift towards Mixed-Model Assembly Lines (MMAL) where EV battery packs and ICE chassis share the same floor, “permanent” is a dirty word.

Our Fully Bolted Structure is designed specifically for this volatility. Unlike Hook-and-Slot systems that can detach when an Underride AGV applies upward lifting force, our racks utilize high-tensile bolts with serrated lock nuts. This creates a rigid frame that withstands the dynamic G-forces of robotic transport without the risk of structural fatigue common in welded joints.

SPS and Line-Side Efficiency

Para Set Parts Supply (SPS) operations, the ability to reconfigure shelf heights and flow angles is critical. If a new door panel is 2 inches taller than the previous model, a welded rack goes to the scrap yard. With our Rack de Fluxo Móvel para SPS, your maintenance team can adjust the levels using standard tools in minutes, not days. This modularity directly supports your Lean Logistics goals by reducing capital expenditure (CAPEX) on new carriers for every minor facelift.

Karakuri Integration: Zero-Energy Automation

The “Easy to assemble” philosophy extends beyond the frame to the automation itself. In many “Dark Factory” initiatives, there is a push to eliminate complex electronics where simple mechanics will suffice. We integrate Karakuri (mechanical shooter) mechanisms directly into the rack structure.

This allows for “Low Cost Automation” (LCA). When the AGV docks at the assembly station, a mechanical lever is triggered, releasing the Rack Automatizado de Caixas KLT stop-pin. Gravity takes over, sliding the box of fasteners or components directly into the operator’s reach or onto the conveyor. No motors, no batteries on the rack, and no complex wiring to assemble—just pure mechanical logic.

Safety and Compliance in Heavy Operations

Ease of assembly does not imply a compromise on safety. In fact, our bolted connections allow for stricter quality control than manual welding. Every joint is a calculated friction grip connection.

For applications involving Módulos de Bateria para EV or heavy Powertrain Components, load stability is non-negotiable. Our racks are engineered to meet ISO 3691-4 safety standards for driverless industrial trucks. We conduct rigorous Center of Gravity (CoG) analysis to ensure that even during an AGV’s emergency stop (E-stop) at 1.5 ft/s deceleration, the Heavy Duty Mobile Dolly remains stable. The use of Q355 High-tensile steel ensures that despite the bolted nature, the frame handles torsional stress far better than brittle welds.
