Abstract
A method is provided to manufacture an elevator including an elevator car and a movable supporting platform. The movable supporting platform is in the elevator hoistway and the elevator car is in the elevator hoistway to transport passengers and/or freight between floors. The elevator car is removed from use, after which a lifting phase is performed, in which the supporting platform above the elevator car is lifted higher up in the elevator hoistway, after which the elevator car is again taken into use to move in the elevator hoistway and to transport passengers and/or freight between floors. Guide rails are installed to extend to above the supporting platform. Guide rail safety gears are arranged during the lift to allow movement of the supporting platform upwards and to grip the guide rails as a consequence of downward movement of the supporting platform.
