Abstract: A system for monitoring the fullness of a compactor waste receiving container utilizes the back pressure generated by the compacted waste for determining the fullness of the container. The compactor ram is stopped when in the forward compacting position and the pressure exerted by the waste on the ram is monitored for thereby determining the fullness of the container. The system further includes a timer for monitoring the time required for displacement of the ram. Should the ram fail to attain the waste compacted position within a pre-determined time period then the hydraulic system is shut down and an indicator is lit in order to show to the operator that the container is full.

Abstract: A pin-off and door closure assembly for a stationary refuse compactor which includes a packer unit having a ram for forcing refuse into a portable container through a load opening in the door thereof, the container being removably attached to the packer unit. The pin-off portion of the assembly includes an elongated pipe which, when not in use, is stored in a refuse-free compartment on the face of the ram. The pin-off pipe is transferred to its position of use across the container door load opening by extension of the ram into the container, following which pins are inserted through both sides of the container into the ends of the pipe for securing the latter into position. A hinged flap forming the forward side of the storage compartment permits the pipe to be removed from the compartment upon retraction of the ram.

Abstract: A compactor packs waste material in an open top container which is adapted for movement inwardly and outwardly of a supporting frame. A ram unit is pivotally supported at one end by the frame with its other end being movable selectively to an extended position within the container, a retracted position above the container, and an intermediate position at the top of the container. A housing encases the ram unit and has an opening for feeding waste material into the container while the ram unit is in the intermediate position. A power unit is operatively connected to and moves the ram unit selectively to the extended, retracted and intermediate position.
