This product is a heavy-duty assembly line engineered specifically for high-payload commercial vehicles, including Pickup Trucks, light-duty trucks, and off-road SUVs. Compared to standard passenger car lines, this system features reinforced chassis carriers and flipping mechanisms to perfectly accommodate body-on-frame construction. It supports mixed-model production for both ICE and Electric Pickups, meeting the demands of high-load, high-tempo industrial manufacturing.
1. Core Processes
1. Chassis Modular Assembly & Flipping
Addressing the body-on-frame characteristics of pickups, the system integrates a dedicated Chassis Flip Machine. The frame enters the line upside-down; the flipping mechanism executes a 180° rotation, allowing operators to ergonomically install the front/rear axles, leaf springs, and drive shafts from a standing position. This significantly enhances workplace safety and assembly efficiency.
2. Cab & Cargo Bed Marriage
The system combines a high-strength EMS (Electrified Monorail System) overhead conveyor with a floor-based skid conveyor. The overhead line handles the precise positioning and transfer of the cab, while the floor line carries the heavy chassis. The system supports flexible switching between long and short cargo beds, enabling mixed-flow production of both Dual Cab and Single Cab pickup variants.
3. Heavy-Duty Logistics & In-Line Assembly
The entire line utilizes reinforced roller beds and heavy-duty skids, significantly increasing per-station load capacity. Integrated in-process pallets facilitate wire harness routing, piping connections, and chassis NVH (Noise, Vibration, and Harshness) treatments during chassis circulation, optimizing the shop floor logistics path.
