るエレベータが開示されている。2. Description of the Related Art In an elevator, a pit is provided at the bottom of a hoistway through which a car ascends and descends, in which various equipment and instruments for operating the elevator are arranged. Conventionally, when inspecting or repairing equipment and instruments in the pit, the car was stopped at a position shifted from the lowest floor,
The elevator door on the lowest floor was left open, and workers entered and exited the pit from there to perform maintenance and inspection work. However, with this method, there is a risk that elevator users or others may accidentally fall into the pit, and workers must descend directly into the pit from inside the car, which is stopped at the bottom floor while the elevator is not operating, to carry out maintenance and inspection work. It would be convenient to be able to do this. For this purpose, in Japanese Utility Model Application Publication No. 2-22979, a pit entrance/exit that opens by sliding a wall plate on the side wall of the car is provided, and a ramp is attached to the wall of the hoistway so that workers can access the car from inside the car. An elevator is disclosed that can pass through the pit entrance and exit, run along the gangway, and descend into the pit.
