Abstract: A roller guide assembly for an elevator device, the roller guide assembly comprising a base member having a mounting means for mounting to the elevator device, the base member comprising a shaft support member; a roller wheel for engaging a guide rail to be rolled on the guide rail; a shaft on which the roller wheel is bearing-mounted, the shaft being straight and non-rotatably supported by the shaft support member, and a vibration dampening element, the vibration dampening element comprising an elastomer body arranged between the shaft and the shaft support member for dampening vibration of the roller wheel and for isolating the vibration from the base member. The shaft is attached to the shaft support member by the vibration dampening element forming a single attachment point for the shaft. The elastomer body is configured to form an elastically spring-loaded universal joint for the attachment of the shaft to provide a universal degree of freedom of an angular movement of the shaft and the roller wheel in relation to the base member.

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.
