Abstract:
A walker system includes a pair of spaced-apart interconnected main beams, designed as a substructure having opposed, laterally spaced-apart side walls structurally bridged for carrying a load above the ground. Lift assemblies mounted on the substructure may engage the ground and raise the substructure to a predetermined height above the ground, and may lower the substructure so that its load is transferred back onto the ground. A shifter mechanism disposed adjacent each lift assembly may displace the substructure along the ground when the lifting assemblies have been extended to raise the substructure above the ground. Auxiliary load bearing members mounted on and extending between the side walls of each main beam engage the ground and distribute the load over the surface area of the auxiliary load bearing members that engage the ground when the lift assemblies have been retracted and disengaged from the ground.
