Recently, skyscrapers are demanded in the downtown area. Increasing of elevator shafts space is an important problem for those tall buildings. This paper proposes a roped Double-Car-Elevator-System to decrease elevator shafts space. Key technologies of the Double-Car-Elevator-System are the system layout, the safety system, the cable-less technique and the operation control. In this paper, we describe the results of basic design and the experimental results of the prototype for these technologies
