Abstract

An apparatus for lifting and tipping a container off of a supporting surface in order to dump contents therefrom, the container being of the type having a bottom wall and upright side walls, the upper extent of which side walls define an opening. The apparatus includes a hook for engaging the bottom of the container and a first support carrying the hook for supporting the bottom of the container through a range of lifting and tipping movement upwardly from the supporting surface and defining a first movement segment wherein the forward side wall of the container in relation to the direction of movement of the container is unsupported. A second support cooperates with the first support for supporting the forward side wall of the container through a second range of lifting and tipping movement subsequent to the first lifting and tipping movement wherein the container is tipped to an angle sufficient to empty the contents therefrom.
