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 embodiment of a system for detecting drift of a building includes a detector that detects at least one horizontal position of elevator roping within a hoistway in or on the building at a selected vertical location. A processor determines at least one characteristic of drift of the building based on information from the detector regarding the detected at least one horizontal position, information regarding tension on the elevator roping, information regarding a density of the elevator roping, and a relationship between the selected vertical location and a length of the elevator roping.
