Abstract: This transfer device is to be supported by the tines of a forklift and supports a load such as a lumber pack to be transferred to a rack cell which have an anchor bar at its opening. The device comprises an underframe having tine receivers, and a mainframe which is movable with respect to the underframe towards the cell opening and which has hooks to hook onto said anchor bar. Said mainframe has rollers on which the load is supported. The system is motorized; first, the load remains centered with respect to the underframe when the mainframe is first shifted laterally of the forklift to hook onto the anchor upper bar of a selected rack cell because the frame rollers rotate in a direction opposite to the shifting direction; then the mainframe rollers rotate in the opposite direction to transfer the load into the rack cell.
