Recently, many high-rise buildings have appeared in residential culture due to rapid industrial development and population growth. It is difficult to evacuate because it is a passageway to the To this end, the law stipulates that buildings over a certain level must be equipped with emergency means of evacuation in case of disaster.

As an existing emergency evacuation method, a sledgehammer that descends along the outer wall of a building by relying on a wire rope is widely used.

However, such a stiffener is very difficult and dangerous for ordinary people to use, and the escape speed is slow, so it is rarely used in practice.

Therefore, as a way to escape in case of a disaster such as a fire in a high-rise apartment or high-rise building, it is dependent on a fire-fighting elevated ladder or a rescue helicopter. However, the fire ladder has a limited height, so it cannot be deployed over a certain height, and the rescue helicopter has a problem with poor accessibility.

In order to solve the above problems, a top-down evacuation ladder has recently been installed that provides an evacuation route to evacuate from the fire floor to the lower floor.
