ABSTRACT:
A freight handling system particularly adapted to transfer palletized loads from one side of a freight dock to another. There is an endless closed loop conveyor comprising an endless chain defining a closed loop path, along which are unidirectional rollers. At spaced locations along the conveying path, there are a number of transfer stations each having a plurality of multidirectional rollers, in the form of casters, which permit pallet loads to be moved onto and from the conveying path. A plurality of pushing devices, particularly adapted for use in the present invention, are mounted to the chain at regularly spaced locations. Each pushing device comprises a push arm which in its operative position has an upwardly and rearwardly moderately sloped push surface which engages a palletized load at a transfer station to move it along the conveying path over the rollers. Each push arm is provided with a releasable holding means which upon release permits the pushing device to pass beneath its load at a selected transfer station, after which the pushing device returns automatically to its operative position.
