Abstract: An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.

Abstract: A belt for suspending and/or driving an elevator car extending longitudinally along a length of the belt. An inner belt layer formed from a first material is bonded to the plurality of tension elements at a first side of the belt. The inner belt layer forms an inner belt surface interactive with a traction sheave of an elevator system. An outer belt layer formed from a second material is bonded to the plurality of tension elements at a second side of the belt. The plurality of tension elements are located between the first side and the second side.

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.

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 plurality of fibers interlaced with the plurality of tension elements forming a composite belt structure. A coating at least partially encapsulates the composite belt structure to improve two or more operational characteristics of the belt. A method of forming a belt for suspending and/or driving an elevator car includes forming a plurality of tension elements and arraying the plurality of tension elements longitudinally along a belt. A plurality of fibers are interlaced with the plurality of tension elements to form a composite belt structure. A coating is applied to at least partially encapsulate the composite belt structure to improve at least two operational characteristics of the belt.

Abstract: A method of fault detection of a belt or rope includes interconnecting a plurality of cords of the belt or rope, the cords including a plurality of wires, to form a bridge circuit. A fault detection bridge circuit is subjected to a voltage excitation and outputs a voltage which is indicative of the belt or rope damage but remaining insensitive to other environmental noises.

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 method of fault detection of a belt or rope includes connecting a fault detection unit to at least a portion of a belt or rope including a plurality of wires arranged in a plurality of strands and/or cords. At least the portion of the belt or rope is subjected to an AC voltage of high frequency range and an electrical impedance of the portion of the belt or rope is measured via the fault detection unit. Using at least the measured electrical impedance of the portion of the belt or rope, a fault condition of the belt or rope is determined.
