A cam frame assembly for a walking system includes a plurality of frame components. The frame components include an upper frame, a lower frame, a front guide frame, and a rear guide frame. At least one of the frame components includes a replaceable wear surface. The replaceable wear surface is an insert retained within a notch in the frame component.

An eccentric assembly for a walking mechanism is provided. The eccentric assembly includes a barrel member and a shaft member. The barrel member includes a circumferential portion extending in a longitudinal direction and a web portion extending inwardly from the circumferential portion. Further, the web portion includes a cut-out region and an inner periphery outlining the cut-out region. The shaft member includes a tubular portion extending in the longitudinal direction and a flange portion extending outwardly from the tubular portion. The flange portion includes an outer periphery. Further, the shaft member is coupled to the barrel member such that the outer periphery of the flange portion substantially conforms to the inner periphery of the web portion. Further, the flange portion is configured to adjust an eccentricity of the shaft member with respect to the barrel member.

A control system retracts lifting devices to a stored reset height during a reset operation to raise support feet off of a base surface. The control device raises a load to a stored moving height above the base surface during a moving operation. The control system automatically repeats the reset and moving operations using the stored reset and stored moving heights. The control device may receive an adjustment signal identifying anew height of the support feet or load bearing frame above the base surface and uses the new height during subsequent reset or moving operations. The control device may default to a minimum reset height or a minimum moving height when the new height would cause the support feet or load bearing frame to drag on the base surface.
