Abstract
An elevator rope speed monitoring assembly is disclosed. The rope speed monitoring assembly includes a plurality of sensors that monitor the movement of the individual ropes. The sensors output a signal indicative of the speed of the movement of the ropes. A controller compares the relative movement of the ropes and generates a warning signal if a sufficient deviation between relative rope speeds is detected.
