Abstract
The self-climbing elevator machine room 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 elevator machine room climbs stepwise along the guide rails by alternatingly locking and unlocking the lower deck and the upper deck to the guide rails and/or to the guide rail fixing means and thereafter raising the unlocked deck.
