ABSTRACT:
A walking beam vehicle is disclosed for supporting a crane or the like which reduces power requirements relative to prior art vehicles. A bi-functional swing drive system is provided for either pivoting the walking beams and a lower frame relative to an upper frame and the ground, or pivoting the upper frame relative to the walking beams and the ground. A power operated lift pad is provided for alternately raising the lift pad and walking beam from the ground. When the vehicle is used as a crane or the like, the walking beams may be extended toward a heavy load to be lifted in order to minimize rollover tendencies of the crane.
