Abstract: The self-climbing installation platform comprises two decks positioned upon each other. Each deck comprises guide means supporting the deck movably on guide rails and locking means locking and unlocking the deck to the guide rails and/or to guide rail fixing means. Lifting means move the two decks along the guide rails in relation to each other. At least one power source provides power to the lifting means. The installation platform climbs stepwise along the guide rails by alternatingly locking and unlocking the lower and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.

Abstract: A safety gear arrangement for an elevator system, comprising a safety gear mechanism comprising at least one wedge portion of the safety gear arrangement, wherein, in a normal position, the at least one wedge portion is retracted and, in an operated position, extended by a first spring element for acting on a guide rail of the elevator system, and a triggering device comprising an electromagnet, a second spring element, an actuating member, and an excitation power input, wherein the electromagnet is arranged, while being supplied with excitation power, to maintain the actuating member in an untriggered position against the second spring element, and the actuating member is arranged to operate the safety gear mechanism in response to moving of the member from the untriggered to a triggered position due to the second spring element.
