Abstract: An illustrative example embodiment of an elevator cab air purification device includes a housing having an inlet, an outlet, and at least one air pathway between the inlet and the outlet. A fan module is situated to cause air flow into the housing through the inlet, through the housing, and out of the housing through the outlet. The air flow through the housing includes air flow along the at least one pathway in at least a first direction. An air purifier is situated within the housing and configured to purify air that flows along the at least one pathway before the air exits the housing through the outlet.

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 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 embodiment of an elevator cab ventilation device includes a fan module and a ventilation controller that is configured to control operation of the fan module based on an indication of a position of at least one door of the elevator cab. The controller is configured to control the fan module to operate in a first mode to move a first amount of air per unit time when the door is in a first open position. The controller is configured to control the fan module to operate in a second mode to move a second, larger amount of air per unit time when the door is in a second, different open 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. 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.
