Abstract: A safety net system is provided for an elevator system that includes an elevator pit and a ladder adjacent to an elevator pit wall for accessing the elevator pit. The safety net system includes a sensor and a processor. The sensor is arranged in a plane between the ladder and the elevator pit wall and is configured to perform sensing to sense an object disposed along the plane and to generate data corresponding to results of the sensing. The processor is operably coupled to the sensor and is configured to analyze the data and to determine whether the data is indicative of a person standing on the ladder based on analysis results.

Abstract: A method of monitoring a tie-down compensation of an elevator system includes positioning one or more sensor assemblies in a hoistway of the elevator system. The sensor assemblies are configured to monitor a position of the tie-down compensation in the hoistway. The tie-down compensation has a compensation member of the elevator system routed therethrough. A distance between a fixed location in the hoistway and the tie-down compensation is measured via the sensor assemblies, and the measured distance is compared to a threshold distance. One or more actions is taken based on a result of the comparison.

Abstract: An elevator system includes a hoistway, an elevator car configured to travel in the hoistway, and a pit located at a bottom of the hoistway. A safety chain is configured to enable or disable motion of the elevator car, and a sensor assembly is configured to initiate opening the safety chain to disable motion of the elevator car upon detection of a person in a detection region of the sensor assembly in the hoistway. A test device is configured to test operation of the sensor assembly to detect malfunctioning and/or tampering of operation of the sensor assembly.

Abstract: An illustrative example embodiment of an elevator compensation assembly includes a tie down mechanism and at least one compensation sheave that has an outer surface configured to engage at least one compensation rope member. At least one damper is associated with the tie down mechanism for resisting vertical movement of the tie down mechanism in at least one direction. At least one detector directly detects vertical movement of the tie down mechanism along the direction and provides an output indicating at least one characteristic of the detected vertical movement.
