Abstract: A method for releasing safety gears of an elevator car or a counterweight of an elevator system, the elevator system including a stalling detector coupled to compensation roping associated with the elevator car or the counterweight and configured to detect an increased rope tension, includes preventing a stalling indication from the stalling detector during a rescue operation; and moving the elevator car in order to release the safety gears.

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.

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 ladder support bracket has a support shoulder for creating a support contact with a complementary backup. The bracket includes at least one jaw for joining the bracket to an upstanding rail of a ladder, the jaw having also a retainer mechanism by means of which the bracket—when being attached to a rail of a ladder—can be brought into a clamping position attaching the bracket unmovably to the rail and a release position holding the bracket in a swivel connection relative to the rail and/or movably along at least a section of such rail.
