Abstract
A landing arrangement of an elevator system includes a plurality of landing bays, at least two landing bays of the plurality of landing bays overlapping, and a plurality of landing door sets. Each landing door set of the plurality of landing door sets corresponds to a landing bay of the plurality of landing bays. At least two landing door sets of the plurality of landing door sets are interconnected such that opening a first landing door set of the plurality of landing door sets urges the at least partial opening of a second landing door set adjacent to the first landing door set.
