摘要： A vehicle, either powered or a trailer (1), having a yoke or U-shaped chassis (2), the tray (3) having parallel posts (13) extending generally upward while the chassis (2) has hollow tubes (12) which mate with the posts (13). Any suitable lifting mechanism preferably hydraulic cylinders (21) located at each corner of the chassis (2) operate simultaneously to raise and lower the tray (3) to maintain substantially the same orientation throughout its movement. A wheel assembly for the chassis comprising first (28) and second (29) trailing arms pivotally suspended from the chassis with wheel mounting stub axles (26, 27) adjacent the free ends, respective connection means (30, 31) adjacent the stub axles (26, 27), a first bracket (36) between the trailing arms (28, 29), and second (39) and third brackets on either side of the first bracket beyond the stud axles (26, 27), a pivoting linkage (37) connecting to the first bracket (36) to two leaf springs (35, 40), the respective connection means (30, 31) connecting the respective trailing arms (28, 29) to the respective leaf springs (35, 40). A hydraulic system for raising and lowering the tray of the vehicle while maintaining its orientation, is also disclosed.
