ABSTRACT:
An elevator installation with an elevator case, an elevator shaft, and a drive unit. The elevator cage is installed in the elevator shaft to be movable and is controllable by the drive unit so that the elevator cage can be stopped in different positions in the elevator shaft. The elevator shaft is equipped with a detecting device which detects whether a person is standing in a critical zone in the elevator shaft or is about to go into this. The detecting device is connected with the drive unit so that the elevator installation can be transferred to a special mode of operation in case a person is standing in the critical zone or is about to go into this. The drive unit includes special control equipment which in the special mode of operation stops the elevator cage before it moves into the critical zone. In that case the detecting device and the special control equipment are designed to be operationally safe in order to prevent movement of the elevator cage into the critical zone. The special control equipment enables, in the special mode of operation, an undisturbed operation of the elevator cage in a zone outside the critical zone.
