てしまう。Problems to be solved by the invention The first rope guide 4 has the same height as the first rope guide 4,
The second and third sheaves 13, 14, and 15 are provided.
The rope guide 5 includes a fourth sheave 16 and fifth and sixth sheaves 17 and 18, and since the fifth and sixth sheaves 17 and 18 are at the same height, the second and third ropes 10 and 11 are Cross-contact occurs at point A, resulting in damage.

プが接触しないようにしたものである。Means and action for solving the problem A holding frame including a first rope guide and a first, second, and third sheave that are shifted in the vertical direction at intervals in the left-right direction is inverted vertically and inverted front-to-back. The structure allows the first, second, and third ropes to be installed by flipping them vertically or backwards depending on how the first, second, and third ropes are wound so that the first, second, and third ropes do not come into contact with each other. This is how it was done.
