Abstract: A belted elevator system (10) includes a hoistway (14) and an elevator car (12) suspended in the hoistway (14) via a suspension member (16) and drivable along the hoistway (14). The suspension member (16) is routed over a plurality of sheaves (18). A sheave (18) of the plurality of sheaves includes a shaft (36) defining a central axis of the sheave (18), the sheave (18) rotatable about the central axis. A sheave outer member (38) is operably connected to the shaft (36) and rotatable about the central axis. The sheave outer member (38) includes a sheave outer surface (44) interactive with the suspension member (16). The sheave outer member (38) is formed from a molded plastic material.

Abstract: A belt for suspending and/or driving an elevator car includes a plurality of tension elements extending longitudinally along a length of the belt, and a jacket at least partially encapsulating the plurality of tension elements. The jacket defines a traction surface of the belt configured to be interactive with a drive sheave and a back surface opposite the traction surface. The jacket is formed from a first material. One or more material strips are located at one or more of the traction surface or the back surface to improve one or more operational characteristics of the belt. The one or more material strips formed from a second material different from the first material.

Abstract: A servicing device for a belt of an elevator system is provided including a housing and a guide member coupled to the housing. The guide member and the housing are disposed on opposite sides of the belt. At least one reservoir is disposed within the housing. The at least one reservoir contains one or more restoring materials. An applicator is configured to apply the one or more restoring materials to an adjacent surface of the belt. Application of the one or more restoring materials is configured to modify the geometry of the belt such that the modified geometry is substantially identical to the original geometry of the belt.

Abstract: A belt for an elevator system and a method for making the same is provided. The belt includes a plurality of tension members that extend along a length of the belt and a jacket. The jacket substantially retains the plurality of tension members. The jacket maintains a desired spacing and alignment of the tension members relative to each other. The jacket includes a plurality of first fibers and a plurality of second fibers. The jacket defines at least one exterior, traction surface of the belt. The first fibers are at least partially disposed between the tension members and the traction surface of the belt. The second fibers are fill fibers. The first fibers have at least one property that distinguishes them from the second fibers.
