Power & Free Systems
A Power & Free System is an overhead conveyor (OHC) consisting of a continuous chain running beneath a rail. Beneath the chain line, an independent load line is installed. The carriers, hang up on the load line, are moved by the chain, when connected (Power). If the load line is disconnected from the chain line, the carrier stands still (Free).
Power & Free conveyors have the same advantages as OHC towards to maximize floor space, sort, buffer, and distribute, and has the supplementary advantage to disconnect the load from the continuously running chain.
