Abstract

An apparatus for dumping refuse containers having outwardly extending co-axial trunnions at their upper front corners. The apparatus consists of two laterally spaced, co-acting mechanisms between which the container is located for dumping. Each of the two mechanisms has a vertically movable lever, both of the levers being pivoted on a common horizontal pivot line on a structure that remains stationary while a container is being dumped. The lower ends of the levers are connected by a cross member which engages the container at a level beneath the trunnions. Each of the mechanisms also has opposed trunnion locks which are moved by a hydraulic cylinder to engage the trunnions. Thereafter, through a lost motion connection, the levers and cross member are swung rearwardly and upwardly by the hydraulic cylinders in order to tip the container over for dumping the refuse. Stop members are automatically moved into position for preventing the container from tipping over beyond inverted position while it is being dumped.
