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 door assembly includes a door panel having at least one edge. A base is configured to be received adjacent the edge of the door panel. An astragal is configured to be at least partially received over the base such that the base holds the astragal in a selected position aligned with the edge of the door panel. The astragal is at least partially compressible for closing off an interface between the edge of the door panel and an adjacent surface.

Abstract: An illustrative example method of positioning an elevator door interlock includes positioning an elevator car in a hoistway near the hoistway door so that at an elevator door coupler is aligned with the interlock, opening a door of the elevator car and the hoistway door, accessing an adjustment mechanism supporting the interlock from outside of the hoistway, and using the adjustment mechanism to adjust a position of the interlock relative to the hoistway door from outside the hoistway.

Abstract: An illustrative example elevator door interlock includes a first base configured to be supported on a hoistway door component, The first base is situated to be selectively pivoted relative to the hoistway door component. A first bumper is supported on the first base such that pivotal movement of the first base changes a position of the first bumper relative to the hoistway door component. A second base is situated to be selectively moved relative to the hoistway door component. A second bumper is supported on the second base such that selective movement of the second base changes a position of the second bumper relative to the hoistway door component. A latch is situated for pivotal movement about a pivot axis relative to the first base between a door locking position and a released position.

Abstract: An illustrative example elevator door interlock includes a latch situated for pivotal movement about a pivot axis between a door locking position and a released position. At least one base is configured to be selectively movable relative to the pivot axis. A plurality of door movement bumpers are supported on the at least one base. Selective movement of the at least one base relative to the pivot axis adjusts an alignment position of the door movement bumpers.

Abstract: An illustrative example elevator system includes at least one elevator car that is moveable along a hoistway. An elevator controller is configured to respond to a communication from a portable device indicating a desire for the at least one elevator car to be placed in a maintenance mode and indicating a location of desired hoistway access. The controller automatically moves the elevator car to a determined positon based on the communication. That position corresponds to the location of the desired hoistway access. The controller performs at least one automated procedure to place the elevator car in the maintenance mode. The controller provides an indication to the portable device that the elevator car is in the determined position and that the automated procedure has been completed.
