Abstract
At a hoistway door on the side of an entrance area there is provided a movable sill that can be moved to uncover an opening that affords access to a machine room lying below the entrance area. The machine room is accessible not only from the access opening, but also from a hoistway pit of the elevator hoistway. When the elevator car is stuck at the lowest floor, emergency operation functions can be carried out through the uncovered access opening. The necessary operating elements of a drive device in the machine room are arranged in such a manner that they can be operated manually through the access opening.
