Abstract
A material handling system for placing and retrieving palletized loads in densely spaced storage areas utilizing an overhead bridge crane connected to a pallet load handling device by way of lifting cables and a stabilizing mast assembly. The pallet handling devices may include vertically or horizontally movable pallet engaging fork mechanisms mounted on a generally rectangular frame which is operable to be lowered over a pallet load and engaged therewith by way of the fork mechanisms. The pallet handling device frame may be split and interconnected by actuator mechanisms to facilitate ease of placing the handling devices over a pallet load and releasing the load from the handling device.
