Elevator shaft

Abstract

The invention relates to an elevator shaft having up to four parallel tracks of the same type, adapted for the operation of a plurality of self-propelled cars per track, and having at least one transfer arrangement for switching tracks and for allowing cars to park on an interim basis, to turn and to pass one another. In order to configure the elevator shaft such that a plurality of cars together can utilize one track in a quadrilateral shaft, it is proposed according to the invention that the elevator shaft has a quadrilateral cross-section of up to four segments each with an independent track, the segments each being disposed such that an axis laid out horizontally through the outwardly-located corner of the cars passes through the center of an imaginary circle which likewise runs through the outer corners of the cars, this center simultaneously forming the center point of the elevator shaft and of the transfer arrangements which have been inserted.
