Abstract
Abstract A frame structure for use in a refuse compactor defining an enclosure of the compacting space. The frame further is formed to define means for guiding the compacting ram in the compacting operation. The frame may be used in conjunction with an outer, one-piece cabinet where the compactor comprises a freestanding compactor, or may itself define the enclosure of the compactor ram and receptacle without the need for an outer cabinet where the compactor is installed as an under-the-counter compactor. The frame may be formed of sheet metal to provide a simple, low cost support structure.
