Abstract
A load-bearing elevator suspension member includes a plurality of tension members and a compressible jacket at least partially encasing the plurality of tension members. The jacket includes a jacket base material mixed with a corrosion inhibitor that establishes a corrosion-inhibiting coating on the tension members. A method of making such a load-bearing elevator suspension member includes mixing the corrosion inhibitor into a thermoplastic jacket material and applying the resulting mixture to bare steel tension members. As the corrosion inhibitor in the mixture contacts the tension members, the corrosion inhibitor establishes a corrosion-inhibiting coating on the tension members.
