ABSTRACT:
A truck comprises a generally U-shaped frame and a dump body pivotally mounted forwardly on the frame and supported on a pair of laterally spaced and parallel side beams thereof. The dump body comprises four triangularly-shaped bottom wall portions converging downwardly to form an inverse pyramidal construction. A double-acting hydraulic cylinder is pivotally interconnected between the frame and dump body to selectively raise the dump body to discharge materials forwardly of the truck. An operator's cab is mounted on a forward end of one of the side beams.
