Abstract
An elevator assembly includes an elevator cabin, a counterweight, a compensating cable and a means for suspending the compensating cable from the elevator cabin. The compensating cable includes a proximal end and a distal end. The proximal end is coupled with the elevator cabin and the distal end is coupled with the counterweight. The means for suspending the compensating cable is coupled with the elevator cabin and is further coupled with the compensating cable adjacent the proximal end of the compensating cable. The compensating cable has an elastic deformation limit. The means for suspending the compensating cable has a tensile strength that is less than the elastic deformation limit of the compensating cable.

Abstract
A compensating cable adapted to attach to an elevator car is provided, wherein the compensating cable includes two portions connected by an arcuate portion. The arcuate portion of the compensating cable defines a loop having an extended diameter such that the compensating cable is capable of attaching to a centerline of the elevator car. Thus, the weight force exerted by the compensating cable on the elevator car may be localized about the centerline such that the elevator car is substantially balanced about the centerline while in operation. In some instances, the compensating cable includes a selected structure and materials suitable for forming an arcuate portion having a suitable loop diameter for attaching the compensating cable to the centerline of the elevator car. An associated system and method are also provided.
