Abstract: An illustrative example elevator sill assembly includes a sill plate and at least one support arm secured to the sill plate. A mounting bracket is configured to be mounted to an elevator car. The support arm is supported on the mounting bracket to allow the support arm to pivot relative to the mounting bracket. At least one linear actuator has a moving portion that moves in a vertical direction to cause the at least one support arm to pivot relative to the mounting bracket to thereby cause the sill plate to pivot from a stored position to an actuated position.

Abstract: A method of monitoring vibratory signatures of an elevator car is provided. The method comprising: detecting at least one vibratory signature of an elevator car, the vibratory signature comprising: a first vibratory signature in a first direction; and determining a probable cause of the at least one vibratory signature by comparing the at least one vibratory signature to a known vibratory signature.

Abstract: A selectively operable braking device for an elevator system. The braking device includes a safety brake adapted to be wedged against a guide rail when moved from a non-braking state into a braking state. Also included is an engagement mechanism moveable between an engaged position and a non-engaged position, the engagement mechanism comprising bar pinions each having teeth and connected to at least one of the other bar pinions with a meshed engagement of the teeth, the engagement mechanism configured to move the safety brake between the non-braking state and braking state when the engagement mechanism moves between the non-engaged position and the engaged position. Further included is a plurality of magnetic brake pads, each of the brake pads coupled to one of the bar pinions, wherein movement of one of the brake pads into the engaged position causes movement of the other magnetic brake pads into the engaged position.
