  • the invention also relates to such a lift installation.
  • the elevator system In order to ensure error-free operation of an elevator system over a longer period of time, the elevator system must be maintained at regular intervals.
  • the maintenance of the elevator installation is usually carried out by a service technician. During this maintenance, the service technician assesses individual components of the elevator system and carries out tests on the functionality of the components. If necessary, the service technician must enter the lift shaft in which the elevator car is moved for this purpose.
  • such maintenance can be carried out from the roof of the elevator car or from the pit of the elevator shaft in which the elevator car is moved.
  • No. 5,476,157 shows an elevator installation with several elevator cars which can be moved within a common elevator shaft. Upon entering the elevator shaft by a service technician, all elevator cars are stopped in order to guarantee a necessary level of safety for the service technician.
  • this has the disadvantage that the maintenance of a single elevator car of the elevator system leads to the fact that the entire elevator installation, ie all elevator cars of this elevator installation are put out of operation, that is no longer available for elevator passengers.
  • the elevator installation which comprises a plurality of elevator cars in a common shaft space, during the maintenance or repair of one of the elevator cars.

  • the invention is based on the finding that the availability and safety of an elevator installation with several elevator cars arranged in a single elevator shaft should be increased during the maintenance / repair of one of these elevator cars. This is achieved by merely putting the first elevator car to be serviced into a maintenance mode or repair mode or stop mode and thus no longer being available to an elevator passenger.
