The tensile carriers are sized so that a total cross-sectional area of all the tensile carriers amounts to 30%-40% of a cross-sectional area of the support means. The tensile carriers may be distributed in a transverse direction of the support means so that exactly two tensile carriers are associated with each of the ribs, the tensile carriers having an outer diameter equal to 35%-40% of a rib spacing (T).

    Abstract: An elevator load bearing assembly includes a plurality of cords within a jacket. The cords are spaced from an exterior surface on the jacket such that the spacing remains generally constant along the length of the belt. The jacket has a smooth, uninterrupted exterior surface for contacting sheaves as the belt moves in the elevator system. A method of making the inventive belt assembly is disclosed. The inventive belt assembly minimizes the possibility for generating an annoying, audible sound and vibration during elevator operation.

    Abstract: A belt monitoring system employs a belt having at least one reinforcement member made from a conductive reinforcement material. A belt monitor is disposed in conjunction with the belt. The belt monitor comprises a field inductor excited by an applied signal. An electrical characteristic of at least a portion of the field inductor as influenced by changes in the electrical properties of the conductive reinforcement member is monitored in order to determine a physical condition of the conductive reinforcement member and thereby monitor a physical characteristic of the belt. This monitoring may be carried out by a sense inductor disposed adjacent or in conjunction with the field inductor.
