A shaft monitoring system for an elevator installation includes a contactless sensor enabling recognition from the elevator car whether a shaft door lock and a shaft door leaf are in a correct locked setting. A securing device mechanically secures the shaft door lock in order to prevent opening of the shaft door and is mechanically and/or electromagnetically actuatable from the elevator car. The contactless sensor includes an active sensor part arranged at the car door and a passive sensor part arranged at the shaft door lock to be monitored. The active sensor part interacts with the passive sensor part as soon as the elevator car stops behind the shaft door and the shaft door leaf and the shaft door lock are disposed in the correct locked setting. The active sensor part also can transiently interact with the passive sensor part when the elevator car moves past the shaft door.
A shaft monitoring system for an elevator installation having an elevator car with a car door and being vertically movable in an elevator shaft, a shaft door by which access to the elevator shaft is closable and which has a door leaf, an automatically locking shaft door lock for locking the door leaf of the shaft door when the door leaf is in a closed setting, wherein the shaft door leaf can be unlocked by the elevator car, and an elevator control, the system comprising:
An elevator installation comprising:
A shaft door lock for an elevator installation, the elevator installation having an elevator car vertically movable in an elevator shaft, the elevator car having a car door, at least one shaft door with at least one door leaf by which access to the elevator shaft is closable, the elevator installation including an elevator control, comprising:
