Abstract: An elevator car or counterweight, comprising a frame, the frame including an upright structure in which a safety brake is mounted so as to allow for lateral movement of the safety brake relative to the upright structure; at least a first vertically or obliquely extending cantilever spring; wherein a first end of the first cantilever spring is mounted to the upright structure; and wherein the first cantilever spring is arranged such that a point remote from the first end provides a biasing force to the safety brake when the safety brake moves away from a default position. As the safety brake is mounted to allow for lateral movement relative to the frame, the safety brake essentially floats relative to the car or counterweight.

Abstract: According to an aspect, a method includes monitoring a plurality of vibration data by a vibration monitoring beacon and determining that the vibration monitoring beacon has been installed at a service location based on detecting an installation characteristic signature in the vibration data. The vibration monitoring beacon can transition into a learning mode based on determining that the vibration monitoring beacon has been installed at the service location. The method can also include monitoring for a learning mode termination event and transitioning the vibration monitoring beacon from the learning mode to a normal operation mode based on detecting the learning mode termination event.

Abstract: An illustrative example embodiment of an elevator system includes a plurality of components respectively configured for at least one function during operation of the elevator system. A plurality of sensors are each associated with at least one of the components. Each sensor senses at least one characteristic of an actual performance of an associated one of the components. A processor is configured to receive respective indications from the sensors regarding the actual performance of the associated components, determine a difference between the actual performance and a desired performance of any of the components based on the respective indications, and determine an adjustment to the operation of the elevator system based upon the determined difference.
