Abstract

A method of 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 walland 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 segament 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. Alternately, the second cooperates with the first support through a second range of lifting and tipping movement but does not actually support the forward wall of the container. An actuator is operatively connected to the first and second support for powering the first and second movement segments.
