摘要: A vehicle is provided with a dump bed which can be pivoted from horizontal orientation to fully upright position facilitate loading of material onto the and unloading therefrom. hydraulic or other type cylinder used raise lower bed. The oriented at an acute angle attached one end rear portion crossbeam forward location. includes downward extending arms extensions that carry pivot pins about rotates. location axis in this manner creates crank arm provides leverage necessary
