<p>PURPOSE:To prevent a bending force from operating at a newly installed wire, and to proceed a smooth and rapid work by providing three rollers selectively in rolling contact with a supporting wire according to positional condition. CONSTITUTION:An approximately triangular closed frame 2 through which a conveyor body can pass therein is formed of a U-shaped arm 1 through which a conveyor can pass, and a pair of openable side arms 3, 4 at both sides. A connecting member 5 for connecting a newly installed wire such as an OPGW is provided at the center of the arm 1. Three rollers 6-8 selectively in rolling contact with a supporting wire such as a drawing wire passing through the frame 2 are provided at the corners of the frame 2.</p> |
