AGV Rack: no se rompe cuando se golpe.

Heavy Duty Mobile Dolly for Automotive SPS Logistics

In the high-stakes environment of an automotive assembly plant, a rack failure isn’t just a maintenance issue—it’s a line stopper. When you are moving 500kg EV battery packs or engine blocks via Underride AGVs, standard warehouse shelving simply cannot handle the dynamic “lift-and-shift” forces. We engineer Fully Bolted, Q355 High-Tensile Steel structures designed to survive the harsh reality of the line-side supply (SPS) zone.

The Engineering Flaw in Standard Racks: Why “Hook-and-Slot” Fails

Most Logistics Managers in the automotive sector inherit a legacy problem: static racks repurposed for mobility. Traditional pallet racking relies on a “Hook-and-Slot” (tear-drop) design. This works fine when gravity is the only force acting upon it. However, the moment you introduce an Underride AGV into the equation, the physics change drastically.

Fig 1. A typical Underride AGV lifting mechanism requires a rigid, bolted frame to prevent beam dislodgement.

When an AGV drives under a rack and activates its hydraulic lift, it exerts a massive Upward Lifting Force. In a standard rack, this force can instantly disengage the beam hooks from the uprights. We call this the “Pop and Drop” effect—the beam pops out, and your expensive powertrain components crash to the floor. Furthermore, the constant vibration from tugger trains or AGV movement causes fatigue fracture in welded joints.

Our solution is a Fully Bolted Structure utilizing industrial-grade lock nuts. This converts the rack into a single rigid frame that withstands vertical thrust, lateral shear during cornering, and the inevitable bumps from forklifts in tight SPS aisles.

Material Science: Q355 Steel for Heavy Payload Stability

Handling EV Battery Modules or stamping dies requires more than just mild steel. Deformation is not an option when you are feeding into automated robotic cells where tolerance is measured in millimeters.

We utilize High-tensile Steel Q355 for our main load-bearing columns and base frames. Unlike the standard Q235 used in light-duty shelving, Q355 offers superior yield strength. This allows us to maintain a high safety factor for heavy loads (1000kg+) without adding excessive deadweight that would drain your AGV’s battery life.

Line-Side Efficiency: Gravity Flow and FIFO

In a Lean Automotive factory, storage is waste. The goal is flow. Your Line-side Supply Racking must facilitate the immediate consumption of parts. We integrate heavy-duty roller tracks directly into the AGV rack structure.

Gravity Flow Rack Integration for FIFO Management

Fig 3. Gravity flow rollers enable FIFO management, crucial for time-sensitive sealants or batch-tracked components.

This Gravity Flow design ensures strict First-In-First-Out (FIFO) compliance, which is critical for batch-tracked safety components like airbags or brake controllers. The angled flow rails automatically present the next bin to the operator, reducing reaching strain and improving cycle time. Combined with our Anti-loosening construction, these racks handle the constant impact of bins sliding down the track without shaking apart over time.

Meeting IATF 16949 Standards

Compliance is non-negotiable. Loose bolts or structural failures are major audit findings in IATF 16949 inspections. Our racks are designed with “Anti-collapse” safety features and undergo rigorous Center of Gravity (CoG) analysis to ensure stability even during AGV emergency stops (E-stops), protecting your workforce and your compliance rating.


Frequently Asked Questions: Automotive Logistics

Q: Can your AGV racks handle the weight of EV Battery Packs (approx. 400-800kg)?

A: Yes. We use reinforced Q355 steel bases specifically calculated for high-density loads like EV batteries. We perform Finite Element Analysis (FEA) to ensure the frame does not deflect during the AGV lift, maintaining safety.

Q: How do you prevent bolts from loosening due to constant AGV vibration?

A: We utilize a specialized Anti-loosening design involving serrated flange nuts and high-torque assembly protocols. This “Install and Forget” approach drastically reduces maintenance downtime compared to standard bolted racks.

Q: Are these racks compatible with our existing Hikrobot or Geek+ AGVs?

A: Absolutely. Our racks are “AGV Agnostic.” We customize the bottom clearance and leg width to fit the specific dimensions and lifting specifications of your Underride AGV brand, whether it’s Hikrobot, Geek+, or MiR.

Q: Can you integrate the rack with our Karakuri (Shooter) system?

A: Yes. We have extensive experience designing racks with mechanical shooter mechanisms for low-cost automation. This allows the AGV to automatically dock and discharge boxes onto the assembly line without human intervention.

Q: Do you offer custom dunnage for protecting Class A surfaces (painted parts)?

A: Yes. For automotive exterior parts (bumpers, doors), we integrate soft-touch dunnage and textile pockets into the steel frame to prevent scratches during transport, ensuring quality compliance.
