Abstract

An elevator system is provided for the transport of loads and/or persons in an elevator shaft. At least two elevator cars can be moved in the elevator shaft and are connected to a counterweight. A drive is associated with each car. At least one common track section and, in addition, separate track sections arranged next to one another are associated with at least two cars. The common track section and the separate track sections are arranged in sections along the elevator shaft. The cars can be moved not only in the same direction but also in directions opposite to one another.
