Abstract
An elevator system, having: an elevator car; a counterweight; compensation cables connecting the elevator car to the counterweight, wherein the compensation cables have a same cable length as each other and each extends from a first end to a second end, wherein the compensation cables are each divided into segments, and each of the segments has a same segment length as each of the other segments, and wherein, in each of the compensation cables, adjacent ones of the segments have a segment density that differs from each other.
Claims20
An elevator system, comprising:
- an elevator car;
- a counterweight;
- compensation cables connecting the elevator car to the counterweight,
- wherein the compensation cables have a same cable length as each other and each extends from a first end to a second end,
- wherein the compensation cables are each divided into segments, wherein along each of the compensation cables, the segments are connected to one another end-to-end, such that the segments are distributed along the cable length, and each of the segments has a same segment length as each of the other segments, and
- wherein, in each of the compensation cables, adjacent ones of the segments have a segment density that differs from each other.
A method of manufacturing a set of compensation cables for an elevator system, comprising:
- forming the compensation cables to have a same cable length as each other such that each extends from a first end to a second end,
- which includes:
- forming each of the compensation cables with interconnected segments, wherein along each of the compensation cables, the segments are connected to one another end-to-end, such that the segments are distributed along the cable length, and each of the segments has a same segment length as each of the other segments;
- and
- forming adjacent one of the segments, in each of the compensation cables, to have a segment density that differs from each other.
