<p>PROBLEM TO BE SOLVED: To provide a metal hanging sheave, while facilitates sag adjustment and protects a cable from falling down to the ground, when the cable is transferred from a guide roller to a cable clamping part. SOLUTION: In order to facilitate sag adjustment, the cable position in a laying state and the cable position in a tension state are made as close as possible to each other to make the transfer distance of the cable small. A movable arm 22, which is a component of a metal sheave 20 is linked with a fixed arm 21 so as to be openable. A linkage part 24 linked with the cable clamp part 5 of an insulator 4 is provided on the upper part of the fixed arm 21. An accommodation space 25, which accommodates in the cable clamp part 5, is formed between the fixed arm 21 and the movable arm 22. A cable guide roller 26 is attached to the lower part of the fixed arm 21 with a shaft. A cable is transferred between the cable clamp part 5 and the cable guide roller 26 in the accommodation space 25.</p> |
