Abstract
An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.
Claims11
A method of making an elongated elevator load bearing member of a traction elevator system, comprising the steps of:
- arranging a plurality of tension elements to establish a desired spacing and alignment of the tension elements relative to each other that the tension elements have when the load bearing member is in use in a traction elevator system;
- and
- subsequent to the arranging and with the established desired spacing and alignment of the tension elements, weaving a plurality of weave fibers together with the tension elements to thereby
- (i) maintain the desired spacing and alignment of the tension elements relative to each other,
- (ii) at least partially cover the tension elements, and
- (iii) establish an exterior, traction surface of the load bearing member comprising exposed ones of the weave fibers.
