<p>PURPOSE:To introduce a high position work vehicle equipped with a manipulator and enable work to be done quickly and safely by fixing the arm of an anchor device to an existing D-shaped arm after assembling a strap, a tension insulator, and an anchoring clamp required for anchoring system on the ground. CONSTITUTION:An anchoring device is lifted above a D-shaped arm 7 by means of a subcrane 5, and the top of the D-shaped arm 7 is set to right below a gap made between right and left arms 8a, and the anchoring device with the right and left arms 8a being set vertically on both sides of the D-shaped arm 7, and the bolt holes of the right and left arms 8a and the corresponding bolt hole of the D-shaped arm 7 are aligned with each other, and then they are fixed by inserting bolts. Next, an aerial cable W is clamped with an anchoring clamp 8e of the anchoring device, and the aerial cable is cut at the right and left positions of an existing through insulator 10, and the existing insulator 10 is removed from the D-shaped arm 7, and then the aerial cable is changed over.</p> |
