Abstract
A method of constructing an elevator, the elevator including a hoistway, an elevator car, a first movable support structure in the hoistway above the elevator car, for supporting the elevator car with a roping, and a roof structure, separate from the movable support structure, in the hoistway above the support structure, where the elevator car is used for transporting passengers and/or goods, and thereafter the first movable support structure is lifted higher in the hoistway, and thereafter the elevator car is used again for transporting passengers and/or goods. The method includes lifting the roof structure higher in the hoistway so as to make more room below the roof structure, the roof structure being a movable roof structure, and in that the movable roof structure is lifted in the hoistway taking support for the lift from a second movable support structure mounted in the hoistway above the roof structure.
