Abstract
An elevator car roof system is provided for monitoring safety of a service access located on an elevator car roof. The elevator car roof system may monitor a change in an opening state of the elevator car roof. Positions of a plurality of roof panels may indicate when the elevator car roof is partially open, fully open or fully closed. The positions of the roof panels may cause at least one sensor of the elevator car roof system to provide a signal to a control system of the elevator. Further, the elevator car roof system may detect if there is an object on the roof. Based on the detected object on the roof, the elevator car roof system may provide at least one signal to enable controlling operation of the elevator.
