Technical Field

[0001] The present invention relates to the technical field of safety protection net installation, and particularly to an installation device and method for an anti-falling safety protection net of an ultra-high tower. Background Art

[0002] With the development of the construction industry, there are more and more ultra-high tower buildings, such as communication towers, transmission towers, sightseeing towers, etc. During the construction and later maintenance stages of ultra-high towers, installing an anti-falling safety protection net is an important measure to ensure the safety of construction workers and prevent objects from falling.

[0003] However, the existing installation methods of protection nets have many drawbacks. The traditional installation methods mainly rely on manual high-altitude operations. Construction workers need to climb to high places with the help of tools such as scaffolding to install the protection net. This method not only has a large labor intensity, but also has extremely high risks in high-altitude operations, and is prone to safety accidents such as falling.
