Problems solved by technology

When inspecting and repairing the power supply equipment, in addition to climbing high, the staff also need to disassemble and replace related parts. Some parts are large in size or heavy in weight, and it is very inconvenient to carry them by manpower alone.
Cranes are usually used for equipment hoisting, while the jibs of traditional cranes are mostly driven by hydraulic pressure. Due to the complex distribution of power transmission lines, the precision requirements for lifting equipment are high. Although hydraulic equipment is controllable, the precision is low, and Unable to adapt to complex environmental requirements for power supply equipment maintenance

Description

technical field [0001] The invention relates to the field of electric power maintenance equipment, in particular to a lifting device for electric power maintenance. Background technique [0002] Power equipment mainly includes two categories: power generation equipment and power supply equipment, and power supply equipment includes transmission lines of various voltage levels. Most of the transmission lines are set in the air, and the transmission lines used by some power supply facilities are numerous and miscellaneous, criss-crossing in the air. When repairing power supply equipment, in addition to ascending heights, workers also need to disassemble and replace related components. Some components are large in size or heavy in weight, and it is very inconvenient to rely solely on manpower to carry them. Cranes are usually used for equipment hoisting, while the jibs of traditional cranes are mostly driven by hydraulic pressure. Due to the complex distribution of power trans...
