  • the present disclosure relates to a pole erection method for erecting poles such as utility poles installed outdoors on the ground.
  • Telephone poles installed outdoors are used by telecommunications companies to support communication cables, and by electric power companies to support cables for power transmission and distribution. It is said that the number of utility poles arranged in Japan is more than 33 million, including communication companies, electric power companies, railway companies, and traffic signals. In addition, the situation is that about 50,000 to 100,000 new trees are constructed every year.
  • Electric poles are long and sometimes heavy, and are often constructed in an environment where there are obstacles such as houses and where people and cars pass, so many workers are used to carry out construction work safely. . Under these circumstances, considering that utility poles will continue to be constructed every year and will increase, and that a large number of utility poles that have already been constructed will need to be renewed due to deterioration over time, etc., it is necessary to efficiently It is required to construct utility poles.
