A self-climbing installation platform includes two decks including an upper deck and a lower deck. Each deck includes a guide element configured to support the deck movably on guide rails. Each deck includes a locking element configured to lock and unlock the deck to the guide rails and/or to guide rail fixing elements. The installation platform includes a lifting element configured to move the two decks along the guide rails in relation to each other, and at least one power source configured to provide power to the lifting element. The installation platform is configured to climb stepwise along the guide rails based on alternatingly locking and unlocking the lower deck and the upper deck to the guide rails and/or to the guide rail fixing elements with separate, respective locking elements and raising an unlocked deck with the lifting element.

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.
