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 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.

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 embodiment of an elevator propulsion device includes at least one drive member configured to engage and climb along a vertical structure, a motor module including at least one motor configured to cause movement of the drive member and corresponding movement of an elevator cab, and a power supply including at least one energy source that is configured to provide power to the motor. The power supply is situated adjacent the motor module such that a mass of the at least one energy source provides a noise barrier to reduce transmission of noise from the motor into the elevator cab.
