Abstract

The present disclosure involves a refuse loading station comprising a refuse packer assembly, a refuse container and a loading dock disposed in front of the packer assembly. The container includes a vertically slidable closure. The clearing member includes a cutter edge for severing refuse, and an inclined refuse deflecting surface located under a bottom edge of the closure when the container is in a refuse loading position. The refuse clearing member includes a mechanism for partially raising the closure in response to movement of the container to a refuse loading position so as to locate the bottom edge of the closure above the deflecting surface. Power actuable mechanism is provided for raising and lowering the clearing member. When the clearing member is raised it contacts and raises the closure, and when the clearing member is lowered it contacts and lowers the closure.
