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. Each tension member includes a core member formed from a plurality of load carrying fibers, and a plurality of overwrap members surrounding the core member. A jacket material at least partially encapsulates the plurality of tension members. An elevator system includes a hoistway, an elevator car positioned in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a plurality of tension members arranged along a belt width and extending longitudinally along a length of the belt. Each tension member includes a core member formed from a plurality of load carrying fibers, and a plurality of overwrap members surrounding the core member.

Abstract: A belt for a lifting system includes a tension member extending along a longitudinal length of the belt. The tension member is formed from a layer of polyethylene material in tape or film form. A jacket at least partially encloses the tension member. The jacket defines a traction side of the belt configured to interface with a traction sheave of a lifting system. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt includes a tension member extending along a longitudinal length of the belt. The tension member is formed from a layer of polyethylene material. A jacket at least partially encloses the tension member, defining a traction side of the belt configured to interface with a traction sheave of an elevator system.

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 defines a traction side of the belt configured to interface with a traction sheave of an elevator system, and is formed from a self-extinguishing fluoroelastomer material. An elevator system includes a hoistway, an elevator car located in the hoistway and movable therein, and a belt operably connected to the elevator car to suspend and/or drive the elevator car along the hoistway. The belt 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 is formed from a self-extinguishing fluoroelastomer material.
