The roller 11a is arranged on the guide rope 2. The interval at which the movable wheel 1 is mounted is set to a length that allows the cable A or the like to move smoothly along the guide rope 2 by winding the extension rope B.

By continuing such work, the leading end of the cable A or the like moves toward the telephone pole X2 while the movable wheel 1 holding the suspension line A1 is guided by the guide rope 2, and the movable pole 1 moves to the power pole X2. The roller 11a of the movable wheel 1 is passed while rolling on the grip 32 of the guide rope support 3 and is guided to the utility pole X3.

When the tip of the cable A or the like reaches the telephone pole X3, the winding drum 56 stops winding the extension rope B, and the hanging wire A1 is connected to the telephone poles X1, X2, X2.
The cable A and the like are simultaneously wired between the utility poles X1, X2, and X3 by fixing to the suspension wire band for securing the suspension wire, which has been installed in advance.

Thereafter, the guide rope 2 is loosened, and in this state, the movable wheel 1 is first removed. At this time, the moving wheel 1
In some cases, the roller 11a of the supporting portion 11 may come off from the guide rope 2. However, even in this case, since the movable wagon 1 holds the suspension line A1 by the retaining portion 13, the supporting portion 11 is moved downward to the suspension line A1. It hangs in an inverted state so that it does not fall.

To remove each movable wheel 1 from the ground, the release gripper 18 of each movable wheel 1 is gripped by the operation rod (not shown) from the ground, and the release rod 17 is connected to the connecting rod 12. This is performed by removing the movable wheel 1 from the suspension line A1 by setting the holding portion 13 to the release position by this pulling.

When the movable wheel 1 is removed in this way, the guide rope support 3 and the securing means are subsequently removed to remove the guide rope 2 from between the utility poles X1, X2, X3, and at the same time, the feed roller 53, 54 and take-up roller 5
5 was removed from telephone poles X1 and X3, thereby
The work of wiring the cable A and the like between X2 and X3 is completed.

In the above-described overhead wire method, the movable wheel 1 of the present invention can be removed from the ground without using an aerial work vehicle, and the entire operation can be performed by the individual wheel. Since only the work is performed on the electric poles X1, X2, and X3, the overhead wire work can be performed in a safe environment.

The cable A and the like can be connected to the power poles X1, X2, and X3 by installing the members on the power poles X1, X2, and X3, and by hooking the hanger A2 on the suspension line A1 by the workers on the power pole X1. It is possible to simultaneously wire the wires between the spaces X1, X2, and X3, and it is possible to greatly reduce the work time required for the wire.

The movable wheel 1 according to the present invention is not limited to the above-described method of wire-laying a cable, but can be used in any method as long as a wire such as a cable is held in the holding portion 13 for wire-laying. Further, the number of wires held by the holding unit 13 is not limited to one, and a plurality of wires can be held.
