Abstract
An elevator system including an interconnected elevator car and counterweight, motive means for driving the elevator car and counterweight, and apparatus for detecting mechanical damage to the elevator system, such as might be caused by an earthquake. An elongated member, such as an electrical conductor, or a conductor of electromagnetic radiation, is disposed along the vertical travel path of one of the movable components, such as the counterweight. The movable component includes a device which severs the elongated member in response to a predetermined horizontal movement of the movable component. A detector monitors the integrity of the elongated member, and it modifies the operation of the elevator system when the elongated member is severed.
