ABSTRACT:
A rescue braking system provides a smoother elevator car movement by mechanically lifting or applying the brake. The rescue braking system incrementally adjusts the force applied to the brake based on the speed and location of the elevator car. Therefore, it can effectively eliminate the jerky vibration and noises caused by the fully on-off brake systems and make the passengers feel more comfortable when the elevator car drifts to the nearest floor door.
