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 sway may be minimized by moving the compensation sheave to adjust the tension of the compensation rope or adjusting the position of the termination of a compensation 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.
