Abstract
A hollow refuse storage body having a longitudinal axis is configured for mounting on a truck chassis. The body has a forward hopper section and a rear section with an open rear end. A tailgate is mounted to the rear section of the refuse storage body and is moveable between closed and open positions to seal and unseal the open rear end of the rear section of the refuse storage body. A hollow box-like load eject blade is mounted within the refuse storage body for reciprocating movement along the longitudinal axis along a bottom floor of the refuse storage body. A hollow box-like packer blade is mounted within the refuse storage body for reciprocating movement along the longitudinal axis overlapping an upper surface of the eject blade. A pair of single stage hydraulic cylinders are coupled in criss-cross fashion between the refuse storage body and the packer blade for moving the packer blade over a first range of travel. The packer blade is moved rearwardly and forwardly in the hopper section and underneath a divider wall of the refuse storage body which prevents spring back of refuse. This permits the packer blade to repetitively push refuse periodically dumped into the hopper sect…
