Hello clever people I'm looking at making a mobile lifting gantry that will support 1000-1500kg max and it needs to be 9ft wide to fit between the beams in the workshop. What size of RSJ do I need obviously overkill as in terms of SWL is a consideration but what does say 63 or 77 meters per ton mean in English?
