Abstract: An illustrative example embodiment of system includes at least one detector that detects a horizontal position of elevator roping at a selected vertical location. The detector provides an indication of the horizontal position at the selected vertical location in two dimensions. A processor determines at least an amplitude and a frequency of sway of the elevator roping in each of the two dimensions at the selected vertical location based on the indication from the detector.

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 elevator system includes an elevator car having an integrated cabin and car frame structure including a platform thickness between a floor surface in the cabin and a lowermost surface on a support beam used for supporting the car beneath the floor surface. A sheave assembly is supported beneath the floor surface. The sheave assembly includes a plurality of sheaves and a plurality of subframe beams. The sheaves and subframe beams fit within the platform thickness such that the subframe beams and the sheaves are no lower than the lowermost surface on the support beam. A plurality of isolation members are between the sheave assembly and the elevator car for isolating an interior of the cabin from vibrations associated with movement of the sheaves.

Abstract: An illustrative example embodiment of an elevator rope sway damping assembly includes a plurality of sway dampers having a width and a length. An actuator device selectively causes movement of the sway dampers in a direction transverse to the length between a first position where the sway dampers are spaced apart by a first distance and a second, sway-damping position where the sway dampers are spaced apart by a second, shorter distance. The actuator device provides an indication when the sway dampers are in the first position.

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 that each have a height aligned with a vertical length of the hoistway. Each of the stationary boundaries has a width generally perpendicular to the height. An elevator car is within the hoistway. At least one vertically extending load bearing assembly includes a plurality of elongated load bearing members extending along a vertical path and facilitating movement or support of the elevator car. At least one hoistway liner assembly is situated in the hoistway. The hoistway liner assembly includes a plurality of bumpers that each have an axis that is generally perpendicular to the vertical length of the hoistway. The axes of at least two of the bumpers are non-parallel. The bumpers collectively establish a protected area sufficient for preventing contact between the load bearing assembly and the interior border of the hoistway if there is lateral movement of any of the load bearing members relative to the vertical path in at least two generally perpendicular directions.
