Rod 43a is sucked out of the hole 36a of the table 36, and the base 13 becomes free in the front-rear direction. Therefore,
A small relative displacement between the moving carriage 11 and the trolley line T due to an error in the stop position of the moving carriage 11 is absorbed here, and an unreasonable force is not applied to each part. Then the motor 5
4, 81 are started, and the Hangaiya holding device 49 turns to approximately 90 ° while advancing to the suspension line M side, and reaches the upper position of the position P4 in FIG. After that, the motors 53 and 54 are started to lower the holding device 49 to the lower position while rotating the holding device 49 in the opposite direction by approximately 90 °. At this time, since the rotation center line L of the holding device 49 coincides with the axis line of the Hangaiya H, the Hangaiya H rotates about 90 ° around the axis. As a result, the suspension wire M is introduced from the open portion 95 of the bent portion 92, and the suspension wire M is guided along the three-dimensional curve of the bent portion 92 to reach the inside of the loop. When the hanger guy H descends to a predetermined position, the trolley wire T cuts in between the pair of open ear pieces 93. During this time, the nutrunner 45
(FIG. 6) advances under the pressure of the cylinder 63 (FIG. 4) and the wrench 59 engages the bolt 94, which is tightened. When the tightening of the bolt 94 is completed, the holding device 49 releases the hanger H and the nut runner 45 retracts and returns to the original position. In addition, when the electric line holding device 65 releases the electric line T and the base 13 is returned to the original position by the pressure of the rodless cylinder 42 below the base 13, the cylinder 4 is released.
The rod 43a of No. 3 projects and fits into the hole 36a, and the base 13 is locked. Further, the motor 33 moves the left-right moving table 23, and the motor 39 moves the lifting table 36.
However, the motors 18 cause the movable carriages 11 to return to their original positions, and one cycle ends. This cycle is repeated at a predetermined interval, and the hanger H is attached to the suspension overhead wire M and the electric power line T one after another. In addition, in the Hangeria attachment device 10, the front-back movement table 23 is fixed.
