Abstract
An elevator system for a building, wherein an elevator shaft becomes taller as the building height increases during a construction phase, includes a self-moving construction-phase elevator car guided on a guide rail section(s) for conveying persons or goods during the construction phase, an assembly platform arranged above the car from which the guide rail section is elongated upwards in a rail assembly phase, an upper protection platform temporarily fixed in the elevator shaft on which the assembly platform is suspended via a cable-based lifting device or is suspended in the rail assembly phase, a lower protection platform, wherein the assembly platform is moved vertically between the upper platform and the lower platform by the lifting device during the rail assembly phase, and a docking device temporarily suspending the car on the lower platform to secure the car for evacuations, the docking device connecting the car to the lifting device.
