Abstract
Abstract A waste compactor includes a horizontally extending compacting chamber with a cantilevered open-ended front section closed by an openable first gate and a chute communicating with a rear upper feed opening. A ram is hydraulically motivated along the chamber between advanced, retracted and intermediate positions. An electrical network controls the ram when the first gate is closed and material sensed in the chute ro reciprocate the ram between intermediate and retract positions until the hydraulic pressure exceeds an adjustable value at the intermediate position and to reciprocate the ram between the retracted position and a point rearwardly of the intermediate position when hydraulic pressure exceeds a second predetermined value. Upon opening of the first gate the ram can be fully advanced.
