ABSTRACT:
The present invention comprises an extensible boom assembly having an anchored end and a distal end. Conveyor means are mounted on the frame assembly for transporting items from the anchored end to the distal end. Takeup means are associated with the conveyor for taking up the slack in the conveyor whenever the frame assembly is retracted and for feeding out the slack in the conveyor whenever the frame assembly is extended. An unloading device is mounted adjacent the distal end of the frame assembly.
The method of the present invention comprises extending a longitudinally extensible conveyor from a loading dock into the trailer of a truck, moving a continuous flexible member mounted on the conveyor in a continuous path from the loading dock into the interior of the trailer, placing items to be loaded into the trailer into engagement with the moving member so that they are carried into the truck trailer, and retracting the longitudinally extensible conveyor to a retracted position where it is removed from the interior of the trailer.
