Power and Free Conveyors
A special adaption of the overhead trolley conveyor and the free line conveyor. A power and free system differs from open and closed track conveyors because the individual carriers can be disconnected from the material flow process, meaning loads are sometimes "free" from the "power" chain. Operations at a workstation can be performed while other material continues to flow. Once operations are complete at a workstation, the load can be reconnected to the conveyor. They are used in warehouse distribution centers, automotive plants, steel mills, foundries, and other types of facilities. Their rugged design makes them ideal for harsh environments. There are two basic configurations of a Power and Free System - Overhead and Inverted.
Overhead Floor - The carriers sit below the track. This allows access to the product from all sides.
Inverted Floor - The carrier sits above the track. The track can be supported from overhead or from the floor.
