More Information
Summary:An elevator load bearing member assembly includes at least one roughened surface (46) on a polyurethane jacket (44) wherein the polyurethane jacket comprises an amide-rich layer on at least one surface. In one example, mechanical roughening is used to roughen the surface (46) after the jacket has been extruded onto tension members (42). Other examples include chemically roughening the jacket surface. The roughened jacket surface improves friction characteristics of a load bearing member assembly.
