Abstract
A lift device includes two vertical extendible tower members, each of the two vertical extendible tower members including, at a first lower distal end, an omnidirectional wheel assembly, and a vertical extension assembly configured to simultaneously raise and lower the two vertical extendible tower members in a vertical direction. The lift device further includes a horizontal extendible transverse member connected between second opposing distal upper ends of the two vertical extendible tower members. The horizontal extendible transverse member further including a horizontal extension assembly configured to extend and retract the horizontal extendible transverse member in a horizontal direction perpendicular to the vertical direction, a traveler carriage configured to move in the horizontal direction upon the horizontal extension assembly between the second opposing distal upper ends of the two vertical extendible tower members, and a payload lifting device configured to raise and lower a payload in the vertical direction with respect to the traveler carriage on the horizontal extension assembly.
