Abstract: A health monitoring system for an electrically-conductive tension member of an elevator system belt includes a transmitter including a transmitter coil configured for placement at the tension member, a receiver configured to be positioned at the tension member, and a controller operably connected to the transmitter and the receiver. The controller is configured to direct an alternating current through the transmitter coil resulting in the generation of a magnetic field and eddy currents at the transmitter coil, evaluate fluctuations in the magnetic field detected at the receiver. The fluctuations are indicative of wear or damage to the tension member.

Abstract: A method of imprinting a belt sheave without removal of an associated belt includes placing a knurling wheel of a tool against a circumferentially extending section of a sheave not in contact with the belt. The sheave is then rotated to induce rotation of the knurling wheel. A jack screw of the tool is actuated to bias the knurling wheel against the sheave for production of imprints upon the sheave.

Abstract: A tension element of an elevator system tension member includes a plurality of first polymer fibers of a first material extending along a length of the tension element, and a plurality of second polymer fibers of a second material different from the first material. The plurality of second polymer fibers have a melting point lower than that of the plurality of first polymer fibers. The plurality of second polymer fibers are fused to the plurality of first polymer fibers to serve as a matrix for the plurality of first polymer fibers.

Abstract: A traction sheave for an elevator system includes an outer sheave surface having a distance from a sheave axis that varies along a width of the traction sheave. The outer sheave surface includes a first portion having a first coefficient of friction and one or more second portions having a second coefficient of friction less than the first coefficient of friction. An elevator system includes an elevator car, a motor and a traction sheave operably connected to the motor to drive rotation of the traction sheave. The traction sheave includes an outer sheave surface having a distance from a sheave axis that varies along a width of the traction sheave. The outer surface includes a first portion having a first coefficient of friction and one or more second portions having a second coefficient of friction less than the first coefficient of friction.

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.
