For construction of overhead power distribution line, it may be difficult to build a rope before wiring power line between utility poles when there are some obstacles between the poles. Multi rotor helicopter (MRH) can fly over the obstacles and carry the rope between the poles. Therefore, it is expected that this work will be facilitated by utilization of MRH. On the other hand, the MRH utilization in the real site causes some risks. If the risk level is unacceptable, the level needs to be reduced to an acceptable range. In this paper, an example of the utilization of MRH in construction of overhead distribution line is introduced. We completed the construction with reducing the risks caused by using MRH to an acceptable range. As the result, the effectiveness and safety of utilization of MRH in the construction are confirmed.
