摘要： An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting movement of the tie down mechanism in at least one direction. At least one detector detects movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected movement.

摘要： Methods and systems for monitoring a dynamic compensation control system of an elevator system are provided. The methods and systems include monitoring a first motion state sensor signal generated by a first motion state sensor, the first motion state sensor associated with an elevator machine, monitoring a second motion state sensor signal generated by a second motion state sensor, the second motion state sensor located on an elevator car, determining an operational status of the second motion state sensor based on an analysis of the first motion state sensor signal and the second motion state sensor signal, and when it is determined that a failure status of the second motion state sensor is present, the method further comprises deactivating a dynamic compensation control mode of operation of the elevator system.

摘要： Disclosed is a car mover, configured for autonomously moving an elevator car along a track beam in a hoistway lane, having: a car mover body; a drive wheel operationally connected a lateral side of the car mover body, and configured to rotate about a drive wheel axis; a first guide wheel operationally connected to the lateral side of the car mover body, wherein the first guide wheel is offset from the drive wheel so that, in operation: the first guide wheel engages a lateral sidewall of the track beam when the drive wheel laterally moves on the track beam, to thereby restrict lateral motion of the drive wheel on the track beam.

摘要： Methods and systems of controlling elevators including detecting a landing stop for an elevator car, measuring load information associated with the stop, controlling stopping of the elevator at the landing using a machine based on at least one of the detected landing and the measured load information and performing dynamic compensation control of a motion state of the elevator with a computing system and the elevator machine. The dynamic compensation control includes receiving motion state information related to at least one motion state of the elevator car at the computing system, receiving the landing and load information at the computing system, applying a filter to the received information and generating a first control signal, and producing a control output from the first control signal to control the elevator machine to minimize oscillations, vibrations, excessive position deflections, and/or bounce of the elevator car at the detected landing.
