Abstract

An example elevator system may include a shaft in which a first elevator car and a second elevator car positioned below the first elevator car are separately movable up and down in a vertical direction along a common guideway. The first elevator car may be coupled to a first counterweight by first suspension ropes and by first compensation ropes, and the second elevator car may be coupled to a second counterweight by second suspension ropes and second compensation ropes. Further, first and second ends of the first compensation ropes may be secured to the first counterweight or to the first elevator car. The first compensation ropes may be guided around at least one roller positioned on a bottom surface of the first elevator car or on the counterweight.
