  • Publication number: 20210214188
    Abstract: A rope pulley of an elevator system is a free rotating pulley around which a hoisting rope of the elevator system can be guided. The free pulley is to be mounted to a car sling of an elevator car. The pulley includes an encoder for measuring the rotation movement of the pulley. The movement data are transmitted to a controller that converts the movement data into position data of the car in the hoistway, while further position data are gathered from identification markers that are installed in the hoistway. At least, the movement data of the rope pulley(s) are calibrated based on the position data from the identification markers. Thereby, the position of the car in the hoistway can be determined accurately and costly.
