Because one end of the small plate chain is fixed to the first stage lifting frame 132, the other end of the small plate chain pulls the third stage lifting frame 134 to move upward. At this time, the small sheave is also equivalent to the movable sheave, so that the rising rate of the three-stage lifting frame 134 is 2 times the rising rate of the two-stage lifting frame 133 and 4 times the rising rate of the one-stage lifting frame 132.
