SYSTEM AND METHOD TO MINIMIZE ROPE SWAY IN ELEVATORS

摘要

A system and method for minimizing compensation rope sway by altering the natural frequency of compensation ropes using servo actuators. The rope swa y may be minimized by moving the compensation sheave to adjust the tension o f the compensation rope or adjusting the position of the termination of a co mpensation rope to account for changes in the position of a structure. Servo actuators may also be used to re-level the elevator car to account for rope stretch.
