Insert the screw and fix it to the SS suspension hardware (not shown).

[Problem to be solved by the invention]

The conventional SS type cable installation method described above not only requires workers to climb utility poles to install metal wheels and pass guide ropes, but also requires workers to pay out the SS type cable from the drum at the starting end. It also requires workers to pull the cable at various points along the span, resulting in a lack of safety and inefficiency.

An object of the present invention is to provide a tip-towing type manipulator cable crossing vehicle that requires fewer times for a worker to go up and down utility poles during construction work, and can reduce the number of people and time spent on construction work. It is in.

[Means to solve the problem]

The cable crossing vehicle with a tip towing type manipulator of the present invention can attach a cable fixing fitting and a metal wheel to a utility pole, and has a manipulator that tows the tip of the rope, and a manipulator that pulls the tip of the cable and fixes it to the cable towing end while towing the tip of the cable. A cable towing guide that allows you to insert the screw through the tool,
A manipulator support arm capable of temporarily suspending a cable from a metal wheel during striding; a cable payout/winding device for feeding out and winding a cable; a rope feeding/winding device for feeding and winding a rope; The manipulator arm, the cable towing guide, the manipulator support arm, and the cable feeding/pulling guide.
It consists of a moving vehicle that transports a winding device and the rope pay-out/take-up device, and each of the cable and rope pay-out/take-up devices includes a drum device that pays out or winds up the cable or rope, and a cable drum that is lowered to the ground. It includes a means for raising and lowering the cable drum, which can be lifted onto the vehicle. [Operation] A cable drum is installed on the ground, and the tip of the SS type cable fed out from the cable drum is held by a cable towing guide, and the cable is towed while applying tension to the cable by the movement of the moving vehicle, so that the tip of the cable is Once the cable has passed the pole, a manipulator is used to attach cable fixing hardware and a safe to the pole, and the cable is then strung by placing the cable on a metal wheel using the cable towing guide that holds the end of the cable. The same applies to rope towing.

Therefore, the number of times the worker has to go up and down the utility pole during the construction work is reduced, and the number of people and time required for the construction work can be reduced.
