Abstract: A method of making a guide rail for an elevator system includes providing a metallic guide rail having a base portion and a blade portion extending from the base portion The blade portion includes one or more guide surfaces interactive with a safety brake of the elevator system. A protective layer is applied to the guide rail for corrosion protection and a perimeter of the protective layer is adhered to the guide rail to seal the guide surfaces from corrosive elements, while not adhering the protective layer to the guide surfaces.

Abstract: A method of monitoring a suspension member of an elevator system includes determining a condition of the suspension member based on a combination of an electrical inspection technique, a use indicator corresponding to an amount of use of the suspension member, and a mechanical characteristic indicator corresponding to at least one mechanical characteristic of the suspension member. The suspension member is removed from service based on an indication from the electrical inspection technique, the mechanical characteristic indicator, and the use indicator satisfying at least one predetermined combination of criteria.

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.
