Claim 0:
1. A lift device comprising:
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; and

a horizontal extendible transverse member connected between second opposing distal upper ends of the two vertical extendible tower members, the horizontal extendible transverse member 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,
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:
a left horizontal end structure configured to be attached to one end of the vertical extension assembly of the two vertical extendible tower members;
an opposite right horizontal end structure configured to be attached to another end of the vertical extension assembly of the two vertical extendible tower members; and
a telescopic slide assembly configured to connect the left and right horizontal end structures to the traveler carriage, the telescopic slide assembly further including
a first pair of telescopic slides attached to the left horizontal end structure and the traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to the horizontal direction; and
a second pair of telescopic slides attached to the opposite right horizontal end structure and the traveler carriage, the second pair of telescopic slides defining a second plane being substantially diagonal to the horizontal direction and substantially orthogonal to the first plane defined by the first pair of telescopic slides.
