Description

[0002] High-altitude electric lifts are specialized equipment for aerial work, widely used in industries such as power, communications, and construction. They are primarily used for inspection, maintenance, and installation work at height. Their basic structure consists of a lifting platform, an electric lift system, and a control system. The lifting platform can carry both personnel and tools.

[0003] At present, high-altitude electric lifting devices have gradually been used in the daily maintenance of power transmission networks.

For conductors with more than four splits, they need to be moved to the maintenance position by themselves. For single-line or double-split conductors, they need to use soft ladders or flying cars to move to the maintenance position. At this time, personal skill levels must be exerted while adding extra physical burden to the high-altitude maintenance personnel, failing to maximize the role of the high-altitude lifting device.
