First claim
Opening claim text (preview).
The invention claimed is: 1. An elevator system comprising: a car; two counterweights; two support means having different physical properties, a first of the support means being connected between the car and one of the counterweights and a second of the support means being connected between the car and another of the counterweights; and wherein the first and second support means are redundant with regard to a maximum load-carrying capacity to be carried in the elevator system. 2. The elevator system according to claim 1 wherein the first support means has a larger safety reserve than the second support means. 3. The elevator system according to claim 1 wherein the first support means is part of a first support means arrangement and the second support means is part of a second support means arrangement, the first support means arrangement having a larger number of the first support means than a number of the second support means in the second support means arrangement. 4. The elevator system according to claim 1 wherein the first support means has larger dimensions than corresponding dimensions of the second support means, the dimensions being at least one of diameter, width and thickness. 5. The elevator system according to claim 4 wherein the first support means has a larger cross-sectional area than a cross-sectional area of the second support means. 6. The elevator system according to claim 1 wherein the first support means has different vibration properties than vibration properties of the second support means. 7. The elevator system according to claim 1 wherein the first support means includes different materials or combinations of materials than materials included in the second support means. 8. The elevator system according to claim 1 wherein the first support means has a cross-sectional area shaped differently than a cross-sectional area of the second support means. 9. The elevator system according to claim 1 wherein the first and second support means have a same expansion properties.
