Abstract
A dual independent hoist arrangement for a breakdown station is shown. The breakdown station includes an input conveyor depositing loads on an L-shaped tilting frame. The tilting frame pivots the load into a transport path whereat one of the two independently operable lifting hoists accepts the load directly from the tilting frame and moves the load along a transport path to a fixed discharge point. Load engaging forks of each lifting hoist move into and out of the load transport path for coordinated use and sequencing of the tilting frame and lifting hoists.
