ABSTRACT:
A wheel support (outrigger) for a rolling and stepping vehicle, especially a crane, excavator or like agricultural, industrial or construction machine in which a leg carries a wheel and is, in turn, connected by a parallelogrammatic linkage to a knuckle which articulates the parallelogrammatic linkage to the vehicle chassis. A further knuckle is provided between the wheel or its leg and the parallelogrammatic linkage. The wheel-carrying outrigger is swingable in a vertical plane while the first knuckle is provided with a vertical pivot axis on the chassis. The outrigger is also provided with an actuating device, preferably a fluid-powered cylinder, which swings the outrigger.
