Abstract
Abstract This invention relates to improvements in the device for opening of body gates of dump trucks or the like described in U.S. Pat. No. 3,173,724. By hinging a separate flap-like element at the bottom at the body platform and pivotally connecting the link of the device according to said patent to said element the gate will be indirectly biassed by the link. The disadvantages of jamming gates is thereby eliminated.
