Abstract
Abstract A refuse handling device comprising a base frame, a packer unit, and a self-dumping container. The packer unit packs refuse and forces it into the container. The container is connected to upstanding frame members, and upon initial extension of hydraulic rams for dumping the container it moves relative to the frame members to break away from the packer unit. Upon continued extension of the hydraulic rams the container is pivoted to a dumping position. The container has a folding door over its dump opening which is normally latched shut and unlatches and folds open automatically upon extension of the dumping rams. A seal is provided between the packing unit and the container, and guide pins ee provided on the packer unit to help align the container with respect to the packing unit.
