What Is a Power & Free Conveyor System?

Automotive Power & Free Conveyor System

Power & Free Conveyor System is a flexible overhead conveying solution widely used in automotive manufacturing and vehicle assembly plants. It combines continuous power-driven movement with independent free trolley movement, allowing vehicles, bodies, chassis or components to be conveyed, accumulated, buffered, stopped, transferred and sequenced according to the production process.

Compared with a conventional continuous conveyor, the Power & Free system provides greater flexibility for production-line layout and vehicle flow management.

China Vehicle Industry Co., Ltd. can provide customized Power & Free Conveyor Systems according to vehicle type, production capacity, plant layout, process requirements and automation level.

Main functions of the Power & Free Conveyor

Continuous Conveying: Vehicles or process carriers are continuously driven by a power chain, ensuring stable transport.
Accumulation: When downstream stations have no immediate production demand, workpieces can accumulate and be buffered in designated areas, reducing the risk of stopping the entire production line.
 Stop & Go: Each process carrier can operate according to specific process requirements: Start → Convey → Stop → Process → Restart
This is ideal for stations on automotive final assembly lines where the vehicle must remain stationary for assembly tasks.

Production Sequencing

Vehicles can be sequenced and their spacing controlled according to the production plan, enabling:
Vehicle sequencing
Production buffering
Model changeover
Line balancing

 
 

Transfer & Routing

Based on the production line layout, the system can be designed for:
Straight conveying
Curve conveying
Transfer
Diverging
Merging
Elevating
Parking
