An update for all these champions for helping me, and for future designers, the formulas I was following, noted in my first post, are correct. The one thing I did not have correct was the strength of the steel SHS member mast. It required to be 350MPa as a minimum, not the 250MPa that I was...
Hi Mike, SnTMan,
The davit isn't attached to a pressure vessel. In this case it is similar to sand bagging..it's a 1 tonne lifting frame...6m tall.
oknow and r6156, I cannot find anything useful in the documents you have suggested, sorry. But Maybe i don't have access to it all.
Thanks heaps!!
You guys are gun! Thank you for your responses. I haven't had to engineer pressure vessels before and I am not familiar with the codes you're referring to, and I don't have the PIP Vessel Standards Detail. My main concern is the height of the davit that I can go to with the lightest SHS...
Hi, I'm working through calculations for a davit arm design, from Pressure Vessel Design Manual 3rd Edition by Dennis R. Moss, to check against my calculations. The web link as follows is best for descibing it: https://www.excelcalcs.com/calcs/search-calcs/Strength/Structural-Details/DAVIT-ARM/...
