<p>PURPOSE:To perform the line attaching work without disassembling a yoke metal fitting on the ground by attaching an upper piece to a steel tower, attaching a part of the line of the extending upper piece to the upper piece, then linking a lower piece to the upper piece, forming the yoke metal fitting, and attaching lines for the lower part to the yoke metal fitting. CONSTITUTION:A metal wheel is attached to a metal-fitting attaching hole 9 of an upper piece 2 on the ground beforehand. The wheel is lifted up and attached to an insulator device. Lines are moved and attached to the upper piece 2. The metal wheel is removed after the lines are attached to clamps C1 and C2. The metal wheels P2 and P3 are attached to an arm A2 with ropes having rudders. The lines are made to extend to the metal wheels P2 and P3. A lower piece 3, to which a pair of linking pieces 4 and 5 are linked on the ground, is lifted with a pulley and linked to the upper piece 2. Thus, a yoke metal fitting 1 is formed. Remaining lines L4-L6 are attached from the metal wheels P2 and P3. Therefore, the line attaching work to the yoke metal fitting 1 can be performed without disassembling the yoke metal fitting 1 on the ground. Thus, the line attaching work can be efficiently performed.</p> |
