Claim 11:
12. A method of operating a lift device, the method comprises:
providing a lift device including
two vertical extendible tower members supporting a horizontal extendible transverse member,
an omnidirectional wheel assembly configured to translate and rotate the lift device,
a payload lifting device configured to raise and lower a payload with respect to the horizontal extendible transverse member and translate the payload in a horizontal direction between the two vertical extendible tower members; and

extending the horizontal extendible transverse member along two pairs of telescopic slides, wherein
a first pair of telescopic slides are attached to a left horizontal end structure of the horizontal extendible transverse member and a traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to the horizontal direction, the first pair of telescopic slides attached from the left horizontal end structure to an upper portion of a first side and to a lower portion of an opposite second side of the traveler carriage, and
a second pair of telescopic slides are attached to a right horizontal end structure of the horizontal extendible transverse member 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, the second pair of telescopic slides attached from the right horizontal end structure to an upper portion of the opposite second side and to a lower portion of the first side the traveler carriage; and

translating the payload lifting device on the traveler carriage within a range motion between the two vertical extendible tower members.
