Abstract: A sheave knurling tool is adapted to knurl a sheave while carrying a belt and coupled to a drive unit for rotation. The sheave knurling tool may include a body, an arm, a jack, and a knurling wheel. The body is detachably coupled to a support structure of the drive unit. The arm is pivotally engaged to the body about a pivot axis. The jack is adjustably coupled to, and extends between, the body and the arm. The knurling wheel is carried by the arm, and the jack is constructed and arranged to pivot the arm toward the sheave thereby exerting a biasing force of the knurling wheel against the sheave.

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: An illustrative example embodiment of an elevator tension member monitor includes an optoelectronic detector configured to be situated near the elevator tension member. The optoelectronic detector provides an output corresponding to a profile of the elevator tension member. A processor receives the output from the optoelectronic detector and determines whether there are any anomalies in the profile of the elevator tension member. The processor reports any determined anomaly in the profile of the elevator tension member.

Abstract: A tension member verification system of an elevator system includes one or more identifier elements located at the tension member. The one or more identifier elements include one or more configuration parameters of the tension member. A detector is positioned and configured to verify presence of the one or more identifier elements, and is configured to read the one or more configuration parameters of the tension member. An elevator system controller is operably connected to the detector and is configured to compare the detected one or more configuration parameters to stored configuration parameters stored at the elevator system controller, and take one or more actions in operation of the elevator system based on the result of the comparison.
