A method for modernizing an elevator system, includes using a first and second car for transporting passengers and/or goods between vertically displaced floors of a building, and thereafter removing the first elevator car from use for transporting passengers and/or goods between vertically displaced floors, and thereafter installing a construction time elevator into the lower end of the first hoistway, the traveling zone of the car of the construction time elevator covering only partially the height of the first hoistway; and thereafter using the car of the construction time elevator and the second car simultaneously for transporting passengers and/or goods between vertically displaced floors of the building, during which using the method includes performing construction work in the first hoistway above the traveling zone of the car of the construction time elevator; and thereafter changing the traveling zone of the car of the construction time elevator to extend higher in the hoistway, and thereafter using the car of the construction time elevator and the second car simultaneously for transporting passengers and/or goods between vertically displaced floors, during which using the method comprises performing construction work in the first hoistway above the traveling zone of the car of the construction time elevator.

Method for modernizing elevator system

An elevator arrangement, in particular a construction time elevator arrangement, includes a hoistway; an elevator car mounted in the hoistway; and a vertically movable support structure in the hoistway for supporting the elevator car, the movable support structure being mounted above the elevator car in the hoistway. The vertically movable support structure includes a first working platform, having a planar working area, and a protective cover above the first working platform for protecting elevator components and/or people below it from falling objects. The protective cover covers most of the cross section of the hoistway.
