'''Kentledge''' or '''kentledge weights''' are slabs or blocks of concrete or of iron (usually [pig iron](/source/pig_iron), sometimes with a cast-in handle to assist moving). They are used within ships or boats as permanent, high-density [ballast](/source/ballast). They may also be used as [counterweight](/source/counterweight)s in cranes such as [tower crane](/source/Crane_(machine))s or [swing bridge](/source/swing_bridge)s like the [Victoria Swing Bridge](/source/Victoria_Swing_Bridge) in Edinburgh. On construction sites, prior to the erection of a building, [static load testing](/source/Static_load_testing) may use a large number of kentledges stacked onto a platform. This platform serves to drive [piles](/source/Deep_foundation) into the ground beneath to test the integrity of the foundation.<ref>{{Cite web |url =http://www.fps.org.uk/fps/guidance/technical/piletesting/06-02-27%20load%20testing%20handbook%20(2006).pdf |title =Archived copy |access-date =2016-12-22 |archive-url =https://web.archive.org/web/20161213035844/http://www.fps.org.uk/fps/guidance/technical/piletesting/06-02-27%20load%20testing%20handbook%20(2006).pdf |archive-date =2016-12-13 |url-status =dead }}</ref><ref>
