ABSTRACT:
Three suspension points 20-22 are arranged in the shape of an equilateral triangle on a vertically movable table 16 and two cables 23-28 are attached to each. Three pairs of hoist members 10/11/12 are arranged on the main body 4, and each hoists a cable from two suspension points.
While preventing oscillation and twist of the vertically movable table and making guide poles unnecessary, high speed vertical rising and lowering is possible.
