Abstract: The present invention is an improved crane comprising a base, a support member connected to and extending upwardly from the base, a deformable member attached to the support member, a microswitch and actuator fastened to the support member and arranged so as to be interactive with the deformable member for sensing the relative displacement of the deformable member with respect to the support member, and a winch/boom lifting system. The deformable member comprises a flange plate fixedly attached to the support member. The flange plate is a load bearing member for the crane. An enclosure is affixed to the flange plate. The switch and actuator portion comprises a bar rigidly affixed to the support member, a microswitch fastened about the other end of the bar, a movement sensor abutting the flange plate, and a control circuitry electrically connected to the microswitch and responsive to the movement sensor so as to enable or disable the lifting system of the crane.

Abstract: A front end mount for a service body to a cab chassis of a truck comprising a first crossmember fixedly fastened to the forward portion of the floor of the service body and extending along the width of the floor and a second crossmember fixedly fastened to the frame at a location corresponding to the location of the first crossmember. The first crossmember is received by the second crossmember such that the vertical movement of said first crossmember is restricted by the shape of the second crossmember. The second crossmember has two parallel sections which define the line of travel of the first crossmember relative to the second crossmember. The second crossmember has a section extending horizontally inward from the end of one of the parallel sections opposite the frame. First and second stops are affixed to the first crossmember generally about the ends of the second crossmember so as to restrict the lateral travel of the second crossmember relative to the first crossmember.
