Abstract

This invention provides a construction for a load-carrying vehicle which permits a dump box to dump either to the rear or to the front. The construction includes a fixed pivot for the dumping box at the rear of the frame, and a displaceable pivot for the box at the forward end of the frame. The frame contains fork means adapted selectively to engage either pivot. Locking means are provided for locking one or the other of the fork means with respect to the associated pivot. A connecting link is provided having one end pivoted at the fixed pivot and the other end pivoted to the dumping box at an intermediate location thereof. A power means such as an hydraulic cylinder is connected between a first location on the frame lying between the pivots and a second location on the box lying between the two fork means. The displaceable pivot is adapted to slide longitudinally with respect to the frame.
