摘要： The invention relates to an elevator safety arrangement comprising a hoistway; an elevator car mounted in the hoistway; a working platform on top of the elevator car; at least one movable balustrade, which is movable between a substantially upright position and a substantially horizontal position; and a sensing arrangement for sensing position of the movable balustrade, said sensing arrangement for sensing position of the movable balustrade comprising at least one sensor for sensing position of the balustrade. Said at least one sensor for sensing position of the balustrade comprises a sensor body and a sensor head, and the sensor head is movable relative to the sensor body, and the balustrade is arranged to move the sensor head when pivoted, the balustrade comprising a cam member pivotal together with the balustrade, the cam member comprising one or more protrusions and depressions, and the sensor head is placed against the cam member for being actuated by aid of at least one protrusion and at least one depression of the cam member.

摘要： 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.
