Abstract: An elevator brake wedge is provided and includes an elongate body having first and second generally opposed major surfaces and first and second generally opposed minor surfaces. The second minor surface has a greater length than the first minor surface. Each of the first and second major surfaces extends between corresponding first and second ends of the first and second minor surfaces, respectively. The second major surface defines low-friction film securing grooves extending from a plane of the second major surface into the elongate body.

Abstract: A belt for an elevator system includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt and a jacket at least partially enclosing the plurality of tension members. The jacket defining a traction side of the belt configured to interface with a traction sheave of an elevator system. The jacket includes a base material layer, and a coating layer positioned over the base material layer formed from a self-extinguishing fluoroelastomer material. A method of forming a belt for an elevator system includes forming a plurality of tension members and encapsulating the plurality of tension members in a jacket. The jacket includes a base material layer and a coating layer formed from the self-extinguishing fluoroelastomer material.
