Editing Double-deck elevator (section)

==Double-deck goods/passenger elevators==
Not all double-deck elevators are used to transport passengers simultaneously in both decks. The second deck in a double-deck car may be used for the transportation of goods, typically outside of peak traffic periods. This technique has the advantages of preventing damage to interior fixtures due to impact from trolleys and not requiring a shaft dedicated to a goods-only elevator car. During peak periods, the elevator is used in passenger-only mode.

As of 2011, no triple-deck elevators have been built, although such a design had been considered for the 163-floor [[Burj Khalifa]] before the final design was scaled back to double-deck.<ref name="Emporis">{{cite web|url=http://www.emporis.com/en/wm/bu/?id=burjdubai-dubai-unitedarabemirates|archive-url=https://web.archive.org/web/20070120063252/http://www.emporis.com/en/wm/bu/?id=burjdubai-dubai-unitedarabemirates|url-status=usurped|archive-date=20 January 2007|title=Burj Dubai, Dubai, at Emporis.com|publisher=[[Emporis]]|accessdate=1 March 2007}}</ref>
