Drive belt is fitted on guide pulleys arranged in multiple sets in compliance with one direction of winding from fixed point to cabin connection point. Groups of pulleys include at least one fixed group and at least one movable group. Mobile group moves together with cabin. In each of groups of pulleys all pulleys of group have same diameter, are made with possibility of rotation around horizontal axes and horizontally arranged so, that to lie in one plane. One direction of winding is either clockwise or counter clockwise. Each group of pulleys includes at least three pulleys. At least one drive belt is wound around the pulleys with provision of a gear ratio of at least 4 to 1.
