Abstract

A method for constructing at least two elevators in a building under construction adapts the usable lifting heights of the elevators to an increasing height of the building, wherein each of the elevators is arranged in an elevator shaft of the building associated with the elevator and includes a drive platform having an elevator drive machine that supports and drives an elevator car and a counterweight by a traction sheave and at least one flexible suspension device. In order to adapt the usable lifting heights, lifting operations are performed in which in alternation one of the drive platforms is raised to a higher level in the associated elevator shaft and is locked there. A single lifting platform is temporarily fastened above the particular drive platform to be lifted to apply a lifting force required to raise the drive platform, which force is transferred to supporting elements of the elevator shaft.
