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.
Claims19
A vehicle comprising:
- a U-shaped chassis formed by:
- a top rail having two substantially parallel arm members and a base member linking said arm members;
- a bottom rail substantially overlaid by said top rail, and having two substantally parallel arm members and a base member linking said arm members;
- and
- a plurality of elongated hollow, substantially parallel members rigidly joining said top and bottom rails;
- a tray having a plurality of posts parallel to each other extending from the tray;
- each of said posts mating in sliding engagement within a respective elongated hollow substantially parallel member, so as to enhance the rigidity of the chassis;
- a wheel assembly located intermediate the ends of each arm member of said bottom rail;
- and
- drive means to move said tray between a raised transport position and a ground engaging loading position such that said tray retains substantially the same orientation throughout its movement between said transport position and said loading position, as a result of the sliding engagement of the said posts within the respective elongated hollow substantially parallel members.

- a bottom rail substantially overlaid by said top rail, and having two substantially parallel arm members and a base member linking said arm members;
- and
- a plurality of elongated hollow, substantially parallel members rigidly joining said top and bottom rails and extending substantially normal to the plane of the chassis;
- a tray having a plurality of posts parallel to each other extending from the tray;
- each of said posts mating in sliding engagement within a respective elongated hollow substantially parallel members, so as to enhance the rigidity of the chassis;
