Abstract
This patent describes a chassis, comprising: a main frame; a wheeled underframe generally planar-parallel with respect to the main frame; means connecting the main frame to the underframe for relative movement between a retracted position and an extended position to decrease and increase the length of the chassis. An additional axle includes wheels, and a supporting means supports the additional axle for raising the wheels of the additional axle to a position off the ground upon retraction of the chassis and for lowering the wheels of the additional axle to a position on the ground upon extension of the chassis.
