The invention disclosed relates to an improved structure for a wheel barrow to provide efficient loading and unloading. The additional method of loading that separates it from existing designs is the ability to load the wheel barrow tub at ground level and then raise the tub to the standard position while maintaining the base of the tub largely horizontal. The movement of the tub is made possible by a parallel linkage to the frame consisting of two arms on each side of the tub. Through geometrical constraints, the arms keep the tub substantially horizontal throughout the entire movement. The ability to remove or rotate the back panel of the tub allows the tub to be loaded at ground level without having to raise the load over the sides of the tub. |
