ABSTRACT:
A lift bed, tandem axle trailer includes a bed with a load supporting base structure and a pair of wheel support arms mounted for pivotal movement about longitudinally spaced apart, transverse axes on each side of the bed for raising and lowering the bed with respect to a road or supporting surface. An axle and wheel is mounted at the outer end of each support arm. A tongue extends forwardly of the trailer bed with the forward end adapted to be hitched to a towing vehicle. Load equalizing linkages are provided between the forward and rearward support arms on each side of the bed and this linkage is interconnected with a lift on each side of the bed for pivoting the support arms to raise and lower the bed to the desired level for loading/unloading or travel. A shock absorber assembly is interconnected with the lift on each side of the bed for providing a smoothed out ride for the trailer bed during travel.
