When the covering of any one of the underground wires is peeled off, an electric short circuit due to a short circuit problem and contact with another wire and Furthermore, there was a very serious problem that could cause the entire underground distribution line to burn out.

In the case of a cable (pipe) that is buried in the ground and accommodates the underground wire inside, after a certain period of time, the exterior surface may be corroded by rain or sewage, or may be damaged by various external factors. Exposed parts of the buried pipe for maintenance and repair are exposed to the outside through excavation work and repair and replacement work is performed.

On the other hand, the excavation work can be quickly and easily withdraw the cable (pipe) buried underground by using a normal fork-lane, the situation of the driver of the fork-lane is not aware of the exact position of the cable (pipe) When the excavation is carried out through the bucket of the fork-lane, the outer surface of the pipe housing the underground distribution line may be hit. In this case, the cable (pipe) may be cracked or broken by the impact, and the cable (pipe) is severely damaged. In addition, there was a serious problem that caused the power supply to be interrupted by damaging the underground distribution line accommodated in the cable (pipe).
