Abstract
Abstract A pair of tie bolts along opposite sides of the compacting cylinder are used to take up the compacting forces by mounting the cylinder door at one end of the bolts and the cylinder ram actuator at the other end of the bolts. The door is hinged to one of the bolts and locked to the other. Since the bolts are spaced from the cylinder a refuse bag can be slipped over the door end of the cylinder, and the door can be replaced with a refuse extruder.
