ABSTRACT:
A trailer is disclosed having a forward section, a middle section, and a rearward section. The forward section is adapted to be attached to the fifth wheel of a tractor while the rearward section supports the trailer on a set of wheels. The middle section extending between the forward and rearward sections is positionable in at least two load-transporting positions at different heights above the ground. The forward and rearward sections each include fixed support elements and locking pins for securing the middle section to the fixed support elements at each of the load-transporting positions. Rollers are provided to guide the movement of the middle section between the load-transporting positions, at least some of the rollers being easily removed to permit front loading of the middle section. An air bag jack is included to move the front end of the middle between the lower-most load transporting position and a ground contacting front loading position.
