Problems solved by technology

[0002] At present, the township power supply stations uniformly use repair vehicles for fault repair, and the bamboo ladder used for repair goes with the vehicle. The bamboo ladder is a whole, including a pair of ladder bars and several step bars in the middle of the ladder bars; during the production process, it is processed into Integral form, inconvenient to disassemble

At the same time, the loading and unloading process is cumbersome, and full-time and part-time drivers are unwilling to cooperate, which increases the work difficulty of the maintenance personnel, and there are even accidents of personal injury caused by borrowing bamboo ladders from users who refuse to bring their own bamboo ladders

Moreover, the action form of climbing the ladder is single. If you do not pay attention, the phenomenon of sliding will easily appear, causing potential safety hazards; at the same time, because the distance between the step bars is fixed, it is not easy to adjust according to the needs of different climbers.
