Abstract

Abstract An apparatus for field loading a plurality of containers onto a transport vehicle, comprises a platform disposed on a transport vehicle; a palletizer operably associated with the platform for progressively stacking a plurality of containers into a preselected stacked configuration from one end to the other end of the platform; and a conveyor for transporting each of the containers from the field onto the palletizer. The palletizer includes a false floor for forming thereon at least a row of the containers. The palletizer includes an elevator operably associated with the false floor for vertically transporting to the false floor each of the containers from the discharge end of the conveyor. The palletizer includes a transfer head for transferring each of the containers from the elevator to the false floor for forming at least a row of containers. The false floor is vertically and horizontally movable for positioning the false floor above at least a tier of previously stacked containers on the platform. The false floor is retractable from underneath the row of containers when the false floor is positioned over the tier of previously stacked containers, to thereby deposit the row of containers over the tier of previously stacked containers.
