This hoistway door (4) has on the side of an entrance area (7) a hinged sill (8). With the sill (8) swiveled up, an opening (11) affords access to a machine room (9) lying below the entrance area (7). The machine room (9) is accessible not only from the opening (11), but also from a hoistway pit (10) of the elevator hoistway (1). When the elevator car is stuck at the lowest floor, emergency operation functions can be carried out through the sill (8) and opening (11), these being swiveled upward. The necessary operating elements of a drive device (12) are arranged in such a manner that they can be operated manually through the opening (11).
