  • Patent number: 11220413
    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.

  • Patent number: 7117978
    Abstract: A dampening device for a compensating cable operably engaged with an elevator car is provided, wherein the compensating cable includes two linear portions connected by an arcuate portion. A first guide including at least one roller member is disposed within the arcuate portion and is configured to dampen oscillation of the compensating cable. At least one sensor device is disposed within the arcuate portion and is capable of operably engaging at least one of the compensating cable and the at least one roller member to sense an entanglement condition of the compensating cable. In some instances, at least one sensor device is disposed outside the arcuate portion, in addition to or instead of the at least one sensor within the arcuate portion, and capable of operably engaging the compensating cable to sense a suspension rope stretch condition. An associated system and method are also provided.

  • Patent number: 6234277
    Abstract: A sway reduction device having a cable receiving section, the cable receiving section being formed of a shock-absorbing material and comprising a flexure portion and an aperture for receiving a cable therethrough. The sway reduction device also includes a mounting section with subsections and at least one mounting member for mounting the sway reduction device to a surface. The subsections are moveable generally toward and away from each other whereby the flexure portion is flexed when the subsections are moved away from each other for installing the sway reduction device around a cable.
