  • Patent number: 10662028
    Abstract: A method is provided for moving an elevator car in a rescue operation after at least one electric elevator brake have been actuated, whereafter the brake is re-opened via a manual brake opening device and operated to allow a movement of the elevator car to a next landing. The manual brake opening device is connected to an end limit indicator detector, which end limit indicator detector is configured to issue an end limit signal when elevator car arrives at an area of an end limit indicator at the end of its movement range of the elevator car in the elevator shaft. When the end limit indicator detector outputs an end limit signal to the manual brake opening device, the elevator brake is actuated by the manual brake opening device to stop the elevator car.
