Abstract:
An elevator system includes a stationary structure, a first sheave rotationally supported by the structure, a rope supported by the first sheave, and an elevator car supported by the rope. A vibration damping device of the elevator system is positioned at a first termination of the rope, and is configured to reduce vibration waves in the rope, thereby reducing noise in the elevator car.
