Description

A live wire lifting device

technical field

The invention relates to the technical field of lifting equipment, in particular to a lifting equipment for live working conductors.

Background technique

The patent document with the patent number CN104340855A provides a live wire lifting device. The special device for lifting large-tonnage wires for live work is a device for lifting large-tonnage wires in the process of high-altitude wiring. The existing large-tonnage wires for live work The lower hook of the special lifting device has no stabilizing device.
