A compactor container comprising a box-like structure having a bottom wall, top wall and a pair of side walls, hollow rib means welded to the outsides of said walls to rigidize said walls and therefore permit said walls to be fabricated of relatively light gauge material, a push-out blade mounted within the container on track means welded to the side walls, and a hydraulic circuit for driving the push-out blade in a first direction during a trash ejection cycle and for resisting movement of the blade in the opposite direction during a trash compaction cycle, said hydraulic circuit including a conduit for effecting communication between a driving motor for the push-out blade and a reservoir mounted on the container, and pressure relief valve means in said conduit for permitting said push-out blade to yield against the force produced by a compaction ram on trash being compacted against said blade when said pressure in said conduit means is exceeded. The pressurized hydraulic fluid for driving said motor means during a trash ejection cycle is provided by a pump mounted on the truck which transports the container to the dumping site.
