The jacking-stations are fed with &#8220;cassettes&#8221;, which are &#8220;lifted&#8221; up to the desired height. Each jack takes 250 tons and can be raised 10 meters without difficulty.<\/p>\n\n\n\n<p class=\" eplus-wrapper\">The system offers several advantages:<\/p>\n\n\n<ul class=\"eplus-wrapper wp-block-list eplus-styles-uid-eeff24\">\n<li class=\" eplus-wrapper\">Greater efficiency compared to traditional jacking-systems.<\/li>\n\n\n\n<li class=\" eplus-wrapper\">Greater control regarding weight\/pressure and lift (stroke-controlled system).<\/li>\n\n\n\n<li class=\" eplus-wrapper\">The system is electric, and you avoid large diesel generators and hydraulic hoses.<\/li>\n<\/ul>\n\n\n<p class=\" eplus-wrapper\">On this project, Simon, Marit and Aleksander operated as jack managers.
