Abstract: A method of remotely tripping an overspeed assembly of a governor assembly includes generating a signal to indicate remote trip, applying power to an actuator, contacting a tripping lever with a movable member operably coupled to the actuator to rotate the tripping lever out of contact with an adjacent swing jaw, and biasing the swing jaw into contact with a ratchet disc capable of limited rotation in response to the tripping lever.

Abstract: An illustrative example elevator system includes a hoistway that establishes a vertical pathway. The hoistway has an interior border established by a plurality of stationary boundaries. The interior border defines a first area. An elevator car is within the hoistway and has an exterior border that defines a second area that is smaller than the first area. At least one hoistway liner assembly is situated in the hoistway. The hoistway liner assembly includes a plurality of bumpers that collectively establish a protected area that is smaller than the first area and larger than the second area such that the elevator car can move through the protected area. The protected area prevents contact between the load bearing assembly and the interior border of the hoistway.

Abstract: An exemplary elongated elevator load bearing member includes a plurality of tension elements that extend along a length of the load bearing member. A plurality of weave fibers transverse to the tension elements are woven with the tension elements such that the weave fibers maintain a desired spacing and alignment of the tension elements relative to each other. The weave fibers at least partially cover the tension elements. The weave fibers are exposed and establish an exterior, traction surface of the load bearing member.
