ABSTRACT:
Method and apparatus for compressing or compacting junk vehicle bodies and the like is disclosed wherein a crushing machine has a frame with a generally horizontally disposed bed and a plurality of upright supports extending from the bed to at least one generally horizontal beam which connects the ends of the upright supports remote from the bed to form a generally rectangular framework with a longitudinal vehicle accepting aperture therethrough. A pair of arms are hinged to the frame at opposite sides of the opening and pivot between generally vertical and generally horizontal positions with a portion of one arm overlapping a portion of the other. The arms are actuated by hydraulic cylinders and are independently movable so that they may be overlapped in either order when in their horizontal positions. The vehicle body is compacted into a relatively flat unitary mass by the arms engaging opposed portions of vehicle side walls near the upper ends thereof and forcing the engaged portions initially, primarily toward one another and subsequently primarily downwardly to flatten a portion of the vehicle body. The body may then be moved and a new portion similarly compacted so that the vehicle body is ultimately folded in and downwardly toward the vehicle frame. A modification for compacting smaller salvageable materials is also disclosed.
