Technical Field

[0001] The utility model relates to the technical field of insulating centipede ladder installation, in particular to an electric lifting device for installing an insulating centipede ladder. Background Art

[0002] When installing a traditional insulated centipede ladder, eight wind cables are usually used for fixing. That is, the operator first pulls up the insulated centipede ladder from the ground through the wind cables, and then fixes the eight wind cables to the ground in sequence. This traditional installation method of the insulated centipede ladder usually requires more than ten operators to install it manually. Not only does it require a large amount of operator input, but the operating efficiency is also very low. In addition, in the process of pulling up the insulated centipede ladder with the wind cables, the insulated centipede ladder is prone to swinging when affected by external forces such as wind, which will have a certain impact on the operator's psychology and physiology. It can be seen that the traditional insulated centipede ladder lifting method has the following disadvantages: large operator input, low operating efficiency, and low operating safety.
