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.
