    Abstract: The invention relates to an elevator system for the transport of loads and/or persons in an elevator shaft with at least two elevator cars which can be moved in the elevator shaft and are connected to a counterweight via carrying means, wherein a drive is associated with each car. In order to develop the elevator system further in such a manner that it can be produced inexpensively and has an improved transport capacity it is suggested in accordance with the invention that at least one common track section and, in addition, separate track sections arranged next to one another be associated with at least two cars in sections along the elevator shaft, wherein the cars can be moved not only in the same direction but also in directions opposite to one another.

  • Patent number: 6189657
    Abstract: A linear motor for lifts for driving a lift car guided in a lift shaft with at least one stator winding row which can be fixed to the lift shaft or to the lift car and with at least one row of exciter magnets of alternating polarity which are situated opposite the stator windings at a distance and which can be fixed to the lift car or the lift shaft, respectively, in such a way that the linear motor exerts only small transverse forces on the motor support and also operates as noiselessly as possible and is easy to assemble, wherein that the stator windings are of iron-free design and are disposed between two mutually oppositely situated exciter magnet rows. In addition, a lift having a lift car which can be driven in a lift shaft wherein the lift has a linear motor of this type for driving the lift car.
