[0019] S2. Setting up the traction rope

[0023] S4. Crossing construction

[0024] In this step, the crane is started and the crane arm is adjusted to the crossing position. The crane auxiliary arm drives the wire turning device to support the traction cable. The traction cable on the side of the crossed line is connected to the ground wire to be pulled.

[0030] 3. By setting the rotating shaft to be rotatable, when the traction rope moves on the rotating shaft, the rotating shaft can rotate along with the traction rope, thereby better protecting the traction rope and reducing the damage to the traction rope. At the same time, the sliding friction is converted into rolling friction to facilitate the movement of the traction rope on the rotating shaft.

[0031] 4. Through the setting of the auxiliary shaft, in this embodiment, the auxiliary shaft is rotatably set on the rotating frame, which can better block the traction rope on the rotating shaft, prevent the traction rope from detaching from the rotating shaft, and improve safety; when the traction rope contacts the auxiliary shaft, the traction rope will drive the auxiliary shaft to rotate, thereby further reducing the loss caused by friction between the auxiliary shaft and the traction rope, and at the same time facilitate the movement of the traction rope on the rotating shaft.

[0032] 5. By setting the guide rod, after the wire turning device body is installed on the crane jib, the traction rope can be better ensured to be in contact with the rotating shaft when the crane jib moves toward the traction rope, thereby improving work efficiency.
