Abstract: A rope sway detection system of an elevator system includes a magnetic pickup located adjacent to a suspension member of an elevator system. The magnetic pickup is configured to detect a movement of the suspension member via a change in a magnetic field at the magnetic pickup. A signal processing unit is operably connected to the magnetic pickup. The signal processing unit is configured to determine a maximum amplitude of a sway of the suspension member based on the change in the magnetic field, compare the maximum amplitude to a preselected threshold, and signal a change in operation of the elevator system based on an actual or predicted exceedance of the threshold.
