The present invention provides a safety device installed in a lower pit of a hoistway, enabling a worker to easily enter an inner way of a pit using a ladder by installing the ladder to be vertical to the pit which is a lower space of the hoistway so that the ladder is stored in close contact with an inner wall side in ordinary times not to interfere with the operation of an elevator and the ladder is separated from the wall side with a preset interval in the maintenance, repair, and check operations of the elevator, and enabling the worker to safely perform maintenance and repair operations by preventing power from being applied to the elevator when the ladder is unfolded.

    본 발명은 승강로의 하부 공간인 피트에 수직으로 사다리를 설치하되, 상기 설치되어지는 사다리는 평소에는 내벽면에 밀착된 상태로 보관되어 승강기의 운행에 간섭되지 않도록 하며, 승강기의 유지보수 및 점검작업시에는 사다리를 벽면으로부터 일정 간격이 이격되게 함으로써, 상기 사다리를 이용하여 작업자가 피트 내부로의 진입을 용이하게 할 수 있도록 함은 물론 사다리가 펼쳐진 상태에서는 승강기에 전원이 인가되지 않도록 하여 작업자가 안전하게 유지 보수 작업을 실시할 수 있도록 하는 승강로 하부피트에 설치되어지는 안전장치를 제공하고자 한다.
