ABSTRACT:
A portable crusher for removeable attachment to the boom structure and hydraulic system of a mobile power source such as a backhoe, or front end loader-type machine for compacting scrap metal and in particular automobile bodies. The crusher includes a frame having a large panel-shaped fixed jaw, integral with and depending from one end of the frame. The portable crusher also includes a panel-shaped operable jaw adjacent the frame and depending therefrom. The operable jaw is connected to the frame by two pairs of links so that the operable jaw can be swung towards and away from the fixed jaw, and so that during such movement the operable jaw is maintained in a substantially parallel relationship with the fixed jaw. The crusher includes a hydraulic cylinder secured on one end to a pair of the links and on its other end to the frame for operating the operable jaw.
