The traction rope 2 passes through the second pulley 8 and then passes through the through hole.
[0032] In combination with Figure 1 shown, a first pulley 7 is installed below the middle position of the horizontal pole of the height limiting gantry 1, the first pulley 7 is level with the second pulley 8, the traction rope 2 that passes through the second pulley 8 then passes through the first pulley 7 and then extends downward.
