ABSTRACT:
A rubber-tired, outriggered vehicle for use as the mounting of a mobile crane is disclosed which has two pairs of telescopic outrigger beams on the opposite sides of the vehicle body, together with a lift cylinder coacting with each outrigger beam for raising and lowering the vehicle body, and an extend cylinder for extending and contracting each outrigger beam. The invention features a hydraulic circuit having two separate valves for independently actuating the two pairs of extend cylinders, in addition to another valve for the actuation of the lift cylinders, so that the vehicle can be crabbed by operating the three valves in a prescribed manner.
