Vertically driving devices 111 to 114 for changing a distance (the effective length) up to the intermediate movable carriage or the lower stage movable carriage from these lower ends, are arranged on the plurality of respective legs or with every leg group being the same position in the horizontally moving direction. Horizontally driving devices 40 and 50 for independently horizontally driving the respective loading space and lower stage movable carriage via the intermediate stage movable carriage, are arranged on the loading space, the intermediate stage movable carriage or the lower stage movable carriage.
