Abstract: An elevator installation includes a first elevator car disposed in a shaft and connected to a counterweight by a first suspension having a first suspension means section, and a second suspension having a second suspension means section. A drive unit moves the elevator car by means of the first suspension. The elevator installation also includes a second elevator car that is movable in the shaft, independently of the first elevator car, via a second drive unit.

Abstract: An elevator system may include upper and lower shuttle cars in a first shaft. The shuttle cars are at least at times fixedly coupled to one another and can move vertically upward and downward together. Upper and lower distribution cars in a second shaft may be movable vertically upward and downward separately. The upper shuttle and upper distribution cars may each comprise a stopping point at an upper shuttle level. The lower shuttle and lower distribution cars may each comprise a stopping point at a lower shuttle level. The second shaft may include a first stop element that can selectively limit a driving range of the upper distribution car to the upper shuttle level and a range vertically above it. A second stop element in the second shaft may selectively limit a driving range of the lower distribution car to the lower shuttle level and a range vertically below it.
