Abstract
A dumping vehicle with a dump bed for holding and dumping material is disclosed. Embodiments include a coupler for coupling the dump bed with a tractor and a linkage connecting the dump bed and coupler, the linkage maintaining the orientation of the coupler steady during dumping. Embodiments include a linkage, dump bed and coupler forming a quadrilateral that deforms during dumping. The linkage can include two arms of different lengths, each pivotally connected to the dump bed and the coupler. In alternate embodiments, the dump bed and a rear support connect at a physical pivot location and the dump bed rotates about a location that is different from the physical pivot location and can rotate about a location that moves. The hinge assembly can include two hinge arms of different lengths that move the dump bed sill rearward and upward as the forward end of the dump bed is raised.
