[0002] In the power supply system, especially in the rural power distribution, various types of pole switches and transformers are the most commonly used power equipment. Generally, these power equipment are installed on the cross arms of two poles to ensure the safety of electricity use. With the development of my country's power industry, more and more power lines are laid, and the installation of corresponding power equipment is also increasing.

[0003] Since these electrical equipment are installed high up on utility poles, workers are required to perform high-altitude operations when inspecting and repairing the electrical equipment.

[0004] At present, conventional high-altitude operations are for workers to wear pole climbers on their feet and use safety belts to slowly climb the poles. After climbing to a high place, the limited space for movement on the crossarms and the restraint of the safety belts greatly affect the workers' maintenance efficiency.

[0005] Therefore, we propose a column-type workbench for high-altitude maintenance to solve the above problems. Summary of the invention

[0006] At present, conventional high-altitude operations are performed by workers wearing pole climbers and using safety belts to slowly climb up the poles. After climbing to a high place, the workers' maintenance efficiency is greatly affected due to the limited space on the crossarms and the restraint of the safety belts. The present invention provides a column-holding workbench for high-altitude maintenance.
