Abstract: A compactor comprising a frame with a fluid operated, double acting ram mounted on the frame. A compactor plate is slidably mounted in the frame to be reciprocable by the ram. A back plate is positioned at an end of the frame remote from the ram. A container receives material to be compacted. The container is mounted adjacent the back plate. The container is open ended and has a top, sides and a base. The base is hingedly attached to one side. The compactor plate can be received in the container so that material in the container can be compacted by the plate. A housing in the container top allows lifting of the container for unloading of compacted material by hinging downwardly of the base. This housing comprises a plurality of open mouthed compartments arranged in a circle and extending upwardly outwardly to receive a grapple of a lifting crane for lifting the container.
