In this way, compared to the rope hanging method shown in Figure 1, which has been used for a long time, the rope hanging method shown in Figure 2 has the advantage that the wrapping angle is approximately twice as large, and the indexing capacity is approximately doubled. However, the disadvantage is that the life of the rope is reduced to about 1/3.
