Abstract:
An elevator load bearing assembly (40) includes a plurality of synthetic or polymer cords (42) within a urethane jacket (44). The cords are prestretched and the jacket prevents the stretched cords from relaxing. The inventive arrangement provides a load bearing assembly (40) that has little or no elastic or construction stretch.
