ABSTRACT:
A truck and trailer assembly adapted to travel over the road in a traveling mode, where the trailer is spaced a substantial distance from the truck, and also adapted to operate in a maneuvering mode where the trailer is more closely coupled to the truck, and the front steerable wheels of the trailer are raised out of ground engagement. In the various embodiments, this is accomplished by rotating the reach of the trailer relative to the trailer, so as to lift the forward wheels of the trailer from the ground. The reach is conveniently shortened by providing the reach as three telescoping members.
