Abstract: An improved roll-back apparatus is disclosed having a deck with a sloping portion at a rearward end which contacts the ground to provide both a low approach angle, and a large support area, for initially receiving the weight of a vehicle to be transported. Slidable slide pads are disposed between the deck and a subframe which slidably supports the deck. The slidable slide pads extend the life of the slide pads, along with reducing the amount of required slide pad material necessary to support the deck upon the subframe.

Abstract: A vehicle trailer assembly is disclosed having a roll back frame for transport of a vehicle. A squat mechanism allows the roll back frame to define a smaller approach angle than normal with respect to the ground when in a loading position. The squat mechanism is self-actuated by movement of the roll back frame to the loading position and is self-releasing by return of the roll back frame to a transport position. The squat mechanism consists of a two bar mechanical linkage that compresses a spring which supports a main frame. By compressing the spring, the main frame is vertically lowered and the roll back frame, which pivots with respect to the main frame moves downwardly through a lesser distance. This lessens the approach angle to the roll back frame.
