THE RACK HAS A MOVABLE STOP ON ITS UPPER SURFACE, SELECTIVELY ENGAGEABLE WITH A CONTAINER BASE, AND A SERIES OF OPENINGS IN ITS LOWER SURFACES ENGAGEABLE SUCCESSIVELY WITH A RATCHETING ACTION, BY THE PUSH-PULL MOTOR ENABLING THE CONTAINER TO BE TRANSFERRED OVER THE SIDE OF THE TRANSFER VEHICLE. A SET OF SLIDABLE SUPPORT BOLSTERS ON THE TRANSFER VEHICLE, EXTENDIBLE AND RETRACTABLE OVER THE SIDE THEREOF, FACILITATE THE TRANSFER OPERATION.
