Abstract:
An elevator load bearing member assembly includes at least one traction enhancing surface (46) on a jacket (44). In one example, a mechanical removal process is used to strip away at least some of an amide-rich layer from the surface (46) after the jacket has been extruded onto tension members (42). In another example, a chemical removal process is used. Another disclosed example includes disrupting the surface.
