A rectangular stabilizing and lifting arm assembly is pivotally connected on one end between a pair of stationary truck frame members and is connected on the outer end by a pair of slide track type connections to oppositely disposed longitudinal members of a dump frame that is pivotally connected to the stationary truck frame members and a hydraulic cylinder assembly pivotally connected on one end to the truck frame members and having the free end of the cylinder rod pivotally connected to the outer free end of the rectangular stabilizing and lifting arm assembly, whereby actuation of the cylinder pivots the latter assembly and the dump frame in an arc from a horizontal position above the truck frame members to a raised dump position.
