ABSTRACT:
A vehicle, either powered or a trailer (1), having a yoke or U-shaped chassis (2) and a drop tray (3) with a tailgate (4) at the rear of the chassis (2) either hinged to the sidewall (6) or to the drop tray decking (5). The tray (3) has parallel posts (13) extending in a general upward direction while the chassis (2) has hollow tubes (12), which mate with the parallel posts (13). Any suitable lifting mechanism could be employed, however hydraulic cylinders (21) are preferable located at each corner of the chassis (2), to operate simultaneously to raise and lower the tray (3) such that it maintains substantially the same orientation throughout its movement between its transport position, above the ground, and its loading position, in which the tray (3) engages the ground.
