ABSTRACT:
An undercarriage (250) is provided for supporting and propelling a mechanism (252). The undercarriage (250) includes a main frame (256) and side frames (258) pivotally mounted at the fore and aft ends of the main frame and on either side thereof. Two axles (270) are rotatably supported on each side frame (258) and on opposite sides of the pivotal axis of the side frame. An inner wheel (266) and an outer wheel (268) are mounted on the axles (270). A double-acting fluid cylinder (284) is interconnected between the main frame (256) and each side frame (258). Pressurized fluid may be provided to the chambers within the fluid cylinders (284) to lock the side frames in a position so that the inner wheels (266) extend below a plane defined by the bottom surfaces of the outer wheels (268) to facilitate skid steering. The fluid cylinders may also be activated to lock the side frames in a position so that the outer wheels (268) are in contact with the surface (272) to lengthen the effective wheelbase of the undercarriage (250). The fluid cylinders (284) may also be interconnected for flow of pressurized fluid so that the side frames (258) form a walking beam arrangement and the load on the inner and outer wheels (266,268) are maintained substantially equivalent. The fluid cylinders (284) may also be activated to position the side frames (258) to level the mechanism supported by the undercarriage (250).
