Fahrgestell AGV: leicht zu uprüsten
Migrating your Powertrain assembly line or Stamping press workshop from forklifts to automation doesn’t require rebuilding your facility. The bottleneck isn’t the robot; it’s the static rack that fails under dynamic movement. We transform your Line-side Supply Racking into mobile, rigid assets capable of handling 2,000+ lbs loads without structural fatigue, eliminating the “forklift rodeo” in narrow aisles.
The Engineering Gap: Why Standard Racks Fail in Auto Manufacturing
In the automotive sector, particularly within Body-in-White or Chassis assembly, the transition to Underride AGVs often reveals a critical flaw in legacy infrastructure: the “Hook-and-Slot” design.
Traditional static racking relies on gravity to keep horizontal beams locked into vertical uprights. However, when a lurking AGV drives underneath and activates its hydraulic lifting mechanism, it exerts an **Upward Lifting Force**. In standard racks, this instantly disengages the safety locks. As the AGV accelerates to transport the payload to the welding cell, the loose structure creates a “wobble effect.”
This isn’t just a noise issue; it’s a catastrophe waiting to happen. For heavy loads like EV Battery Modules or stamped metal parts, this vibration leads to metal fatigue and potential collapse.

The Spacedas Solution: Fully Bolted Rigid Frames
To upgrade your facility for automation, we replace the gravity-dependent connections with a Fully Bolted Structure utilizing Q355 High-tensile Steel.
* **Anti-Loosening Logic:** Every joint is secured with serrated lock nuts that resist the high-frequency vibrations caused by AGV travel over expansion joints in the factory floor.
* **Torsion Resistance:** Unlike welded racks that can crack under the twisting torque of an AGV turning on its axis, our bolted assembly allows for micro-adjustments, dissipating stress while maintaining structural integrity.
* **Zero-Drop Risk:** The frame becomes a singular rigid unit, ensuring that expensive dies or engine blocks remain secure during the 1G acceleration/deceleration phases of transport.
SPS and Line-Side Logistics: Enabling True FIFO
The goal of modern automotive logistics, specifically Set Parts Supply (SPS), is to reduce line-side inventory depth. You cannot afford to have huge pallets of “just-in-case” stock blocking the aisle. You need a flow.
Our Mobile Flow Rack for SPS systems integrates directly with your production Kanban. By utilizing **Gravity Flow** roller tracks within the mobile rack, we ensure strictly enforced First-In-First-Out (FIFO) management for time-sensitive materials like sealants or pre-greased bearings.

The Karakuri Advantage (Shooter System)
For assembly stations requiring rapid box exchange, we integrate **Karakuri** (low-cost mechanical automation) elements. When the AGV docks at the workstation:
1. The rack mechanically interlocks with the station.
2. A side lever is triggered, releasing the **KLT Box** or bin.
3. Gravity shoots the box onto the assembly workbench.
4. The AGV departs, and the safety stop automatically re-engages.
This mechanical “Shooter” capability eliminates the need for the operator to walk into the AGV path to retrieve parts, significantly improving safety scores and cycle time.
Seamless Integration with Existing Fleets
A major hesitation for Plant Managers is compatibility. “Will this rack work if we switch from Hikrobot to Geek+ next year?”
Our engineering philosophy is device-agnostic. The base of our Hier ist das kl-t-gerüst is designed with an open architecture to accommodate the dimensions and lifting heights of 90% of the market’s **Underride AGVs**.
We incorporate a **QR Code Calibration Matte** area and laser-cut positioning slots underneath the rack. This ensures that whether your AGV uses SLAM navigation or QR tape, it can calculate the Center of Gravity (CoG) within ±0.2 inches, preventing off-center lifts that cause tipping.

Technical Comparison: Static vs. Spacedas Mobile Upgrade
| Feature | Traditional Static Rack | Spacedas AGV Flow Rack |
|---|---|---|
| Connection Type | Hook & Slot (Gravity dependent) | Fully Bolted (8.8 Grade) |
| Dynamic Load Handling | Low (Risk of beam detachment) | High (Designed for 1G acceleration) |
| Inventory Logic | LIFO (Last In First Out) | FIFO (Gravity Flow / SPS Ready) |
| Floor Space Usage | High (Requires forklift aisles) | Optimized (-60% aisle width) |
Frequently Asked Questions
1. Can these racks handle heavy automotive dies or powertrain components?
Yes. Our racks utilize Q355 High-tensile steel and can be engineered to support payloads exceeding 2,200 lbs (1000kg). We perform Finite Element Analysis (FEA) to ensure the frame remains rigid during the AGV lift and transport phases.
2. How do you prevent parts from falling off during AGV emergency stops?
We calculate the friction coefficient and tilt angle for every design. For open Line-side Supply Racking, we install mechanical interlocks or slightly backward-tilted shelves that keep KLT boxes secure even if the AGV decelerates at 0.5G.
3. Are these racks compatible with our existing Tugger Train system?
Absolutely. We can design hybrid bases that allow the racks to be towed by tugger trains for long-distance internal logistics, while still retaining the clearance for Underride AGVs to perform the final “last mile” delivery to the assembly cell.
4. What maintenance is required for the bolted structure?
Minimal. Unlike welded racks that may develop hairline cracks requiring hot work permits to fix, our **Anti-loosening** lock nuts are designed for “install and forget.” However, we recommend an annual torque check as part of your standard ISO/IATF 16949 audit procedures.
5. Do you support custom dimensions for specific car parts (e.g., bumpers or exhaust systems)?
Yes. We do not force standard sizes. We build the Mobile Flow Rack around your specific part geometry (dunnage) and the footprint of your chosen AGV, ensuring maximum density without overhang risks.
