Abstract
An exemplary elevator system includes a first mass that is moveable within a hoistway. A second mass is moveable within the hoistway. A plurality of elongated members couple the first mass to the second mass. At least one damper is positioned to selectively contact at least one of the elongated members if sway occurs. A sensor is associated with the damper. The sensor detects contact between the damper and the at least one of the elongated members. A controller adjusts at least one aspect of elevator system operation responsive to the detected contact.
