== Sizes == [[File:MARSEILLE MAERSK (2018) (26339401978).jpg|thumb|Low-profile super-post-Panamax cranes in the [[Port of Rotterdam]]. These cranes have an outreach of 25 rows of containers.]] Container cranes are generally classified by their lifting capacity and the size of the container ships they can load and unload. === Smaller sizes === Smaller container cranes, such as [[straddle carrier]]s, are used at [[Siding (rail)|railway sidings]] to transfer containers from [[flatcar]]s and [[well car]]s to [[semi-trailer]]s or vice versa. Both the rolling stock and the trailers may pass under the base. Smaller container cranes are also used at [[Break-of-gauge#Containerisation|break-of-gauge]] [[Transloading#Transloading facilities|transloading facilities]]. === Panamax === A [[Panamax]] crane can fully load and unload containers from a panamax class container ship capable of passing through the Panama Canal.<ref>{{Cite web|url=http://www.pancanal.com/eng/maritime/notices/n01-05.pdf|title=Vessel Requirements|date=January 1, 2005|publisher=Panama Canal Authority|access-date=September 26, 2016|archive-date=June 11, 2011|archive-url=https://web.archive.org/web/20110611094533/http://www.pancanal.com/eng/maritime/notices/n01-05.pdf|url-status=dead}}</ref> === Post-Panamax === A "post-Panamax" crane can load and unload containers from a container ship too large (too wide) to pass through the [[Panama Canal]]. === Super-post-Panamax === [[File:Roberts Bank Superport aerial view 2014.jpg|thumb|[[Roberts Bank Superport]] aerial view (2014)]] The largest modern container cranes are classified as "super-post-Panamax". A modern container crane capable of lifting two {{convert|20|ft|m|adj=mid}} long containers at once (end to end) under the telescopic spreader will generally have a rated lifting capacity of 65 tonnes. Some new cranes have a 120-tonne load capacity, enabling them to lift up to four {{convert|20|ft|m|adj=mid}} or two {{convert|40|ft|m|adj=mid}} containers. Cranes capable of lifting six 20-foot containers have also been designed. Post-Panamax cranes weigh approximately 800β900 tonnes, while the newer-generation super-post-Panamax cranes can weigh 1,600β2,000 tonnes. The largest Super-post-Panamax cranes have an outreach of 26 container rows.<ref>{{Cite web|title=RWG ontvangt 's werelds grootste containerkranen|url=https://www.nieuwsbladtransport.nl/havens/2020/04/24/rwg-ontvangt-s-werelds-grootste-containerkranen/ |first1= Rob |last1=Mackor |date=24 April 2020 |url-access=subscription |access-date=2020-07-31|website=Nieuwsblad Transport|language=nl-NL }}</ref>
