Abstract
An improved lifting and tilting device for emptying garbage containers into the pour-in opening of a garbage truck. The device comprises a quadrangle of joints of a collapsible frame which carries the container during the emptying process. An upper bar of the quadrange is coupled to a swivel drive while another member of the quadrangle can grip and support the garbage container. Through appropriate locking devices the quadrangle becomes a quasi-rigid unit with the gripped container to effect the emptying, said quasi-rigid unit being dissolved only during the downward swivel motion of the upper bar prior to putting the container down.
