<p>The present invention relates to an evacuation ladder used in the event of fire or an emergency in a high-rise building and, more specifically, to an evacuation ladder which is installed on a moving path connected to the lower floor through the floor of a building in order for a foothold to be unfolded downwards by gravity to provide an evacuation route when a lever is released in the event of an emergency and to be restored to the original state by being pulled by a wire when the emergency is cleared so that the foothold can be reused.</p> |
