摘要： A lifting jack assembly for use on a walking machine to raise it off the ground and preselect a steering direction before the walking machine is lowered onto the ground for travel therealong includes a hydraulic power-driven lift cylinder for actuating an extendable/retractable rod, wherein the lift cylinder is rotatable about its vertical axis. A roller assembly is provided with rollers mounted to the rod. A foot plate mounted below the roller assembly engages the rollers, and a power-driven shifter mechanism mounted on the foot plate and connected to the roller assembly shifts the roller assembly along the foot plate. A linkage assembly interconnects the lift cylinder to the foot plate. A steering mechanism rotates the lift cylinder about its vertical axis to impart rotation to the foot plate and the roller assembly to orient and fix the direction of travel of the walking machine in a preselected direction.
