Background
The power and communication system is necessary for high-altitude operation, and is assisted by a special climbing tool. The work high above the ground generally means work high above the ground, and means work performed by a person at a height with reference to a certain position. The national standard GB/T3608 and 2008 high place operation classification stipulates that the operation at high places with the possibility of falling more than 2m (including 2m) of the falling height reference surface is called high place operation. In accordance with this regulation, the range of high-altitude operations involved in the electrical power industry is quite wide. In the power construction work, if the operation is performed on a frame with the length of more than 2m, the high-altitude work is obtained. The correct selection of the climbing tool and the skilled control of the method of using various climbing tools are one of the important conditions for ensuring the safety work of electricians. The common climbing tools comprise ladders, pedals, climbers and the like, the auxiliary climbing tool comprises a waistband, a safety rope and a waist rope, the climbing operation articles comprise lifting ropes, lifting bags and the like, and certain safety risks exist in use. For high-altitude operators, the extensive pole climbing operation in mountainous areas and rural power lines is quite common nowadays. The construction, operation and maintenance of new electric power and communication projects can not be operated at high altitude. The labor intensity of the climbing operation is very high and the safety factor is not high during the high-altitude operation. Therefore, the labor intensity of operators is reduced, the novel pole climbing tool for cement poles and steel pipe poles is manufactured according to the requirements of the current safety form, and the novel pole climbing tool is used for construction and emergency repair of electric power and communication systems.
