ABSTRACT:
An apparatus for limiting the oscillation amplitude of elevator suspension and compensation elements in an elevator system. The elevator system includes a counterweight movable in guide rails with a suspension element connected to a top of the counterweight and a compensation element connected to a bottom of the counterweight. One or more limiting frames may be employed in the elevator system and each limiting frame surrounds each of the counterweight, guide rails, suspension elements, and compensation elements. Each limiting frame may be attached to the guide rails to limit lateral deflections of the suspension and compensation elements. The limiting frame may include two separate portions which are spring biased together on a stop portion located behind the guide rails, such that excessive deflection of the suspension and compensation elements cause the spring biased portions to separate and activate a safety switch.
