Abstract
An elevator installation erection method includes installing in an elevator shaft: a construction phase elevator system having a self-propelled elevator car whose usable lifting height is adapted to an increasing elevator shaft height; at least one guide rail in the elevator shaft guiding the elevator car along its travel path; and a drive system driving the elevator car and including a primary part attached to the elevator car and a secondary part attached along the elevator car travel path, wherein the guide rail and the secondary part are gradually extended upwards during the construction phase, wherein the self-propelled elevator car transports persons and/or material for the construction of the building and passengers and freight for floors already used as residential or business premises, and wherein after the elevator shaft has reached its final height the construction phase elevator system is replaced by a final elevator system.
