[0002] At present, there are mainly two types of devices for tower climbing fall protection: using double extension ropes, double hook fall arresters, and safety rings. Since the use of these fall prevention tools changes the original tower climbing habits of the operators, it consumes a lot of physical energy of the operators, and invisibly increases the risk of falling when climbing the tower. Currently, the front-line teams are not willing to use them; installing fall prevention ladders, fall prevention rails, and fall prevention steel wire ropes. These fall prevention devices require power outages to install, which is costly and requires large investments. They are difficult to maintain in the later stages and are not conducive to large-scale promotion.

[0013] As a preferred solution of the anti-falling device of the present invention, wherein: the descent of the outer sleeve rod drives the closing of the movable claw;

[0014] The rising of the outer sleeve rod drives the opening of the movable claw.

[0015] Another object of the present invention is to provide a control system, which aims to solve the problem of how to transport the anti-fall device to a designated location.
