  • Trailer mounted automobile crusher
    Patent number: 4036125
    Abstract: An automobile crusher which is readily adaptable for trailer mounting includes a reinforced elongated bed, a crushing roller positioned transversely of the reinforced bed and a hydraulic piston/cylinder arrangement for powering the crushing roller down the length of the bed and over an automobile or the like. A side plate arrangement secured to the roller limits the vertical movement of the roller relative to the bed. The crusher flattens vehicle bodies and the like by the weight of the roller and by forcing the automobile through the limited vertical space between the roller and the reinforced bed.
