Abstract: An elevator system includes an elevator car and a laser distance measuring device. The elevator car is moved along a travel path that is delimited at the top by an upper boundary and at the bottom by a lower boundary. The laser distance measuring device emits a laser beam and determines a distance to a position at which the laser beam impinges on an object. The laser distance measuring device is mounted on the elevator car such that the laser beam can be directed upward to the upper boundary in a first configuration and can be directed downward to the lower boundary in a second configuration. A current position of the elevator car can thereby be determined in a redundant manner. Furthermore, in a third configuration, lateral distances to boundary markers can be measured to read out information that is codified by the boundary markers.
