Abstract: A construction vehicle has a pull hook arrangement mounted on a rearward end of a frame thereof for towing purposes. Such arrangement comprises a pull hook and energy absorbing means normally secured between the frame and the pull hook and adapted to break-away from the frame when the load on the pull hook exceeds a predetermined magnitude. The energy absorbing means preferably comprises a tubular member which is tapered-down rearwardly to thereafter permit it to be drawn through an aperture formed in the frame to absorb energy thereby.

Abstract: an integral welded main frame for a loader vehicle having a hydrostatic drive system, including a front frame section for supporting a load forwardly thereof, a pair of rails extending rearwardly from the front frame section, each of the rails including an upper plate and a lower plate joined by an outer plate and an inner plate to form a box section, the inner plate having an opening for receiving a hydraulic motor of the system, a first casing for a final drive of the system, including a first curved plate surrounding the final drive and the opening and extending from the inner plate to outside the outer plate, whereby each rail is reinforced in the area of the opening, a second casing for a pivot bar extendable through one of the rails, including a second curved plate welded to the outer plate and extending outside thereof, whereby each of the rails is reinforced in the area of the pivot bar, and a plurality of cross-members connecting the pair of side rails.
