Absolutely Desertfox.
Top assembly (150KG) 4 x 16mm rods are screwed into M12 tapped holes on 166mm PCD.
Other end of these rods sit in 17mm diameter counterbored holes that are 10mm deep in the top face of the support plate. This end of the rods is tapped M12 and are fixed in place through...
Desertfox/NRP99/rb1957/HTURKAK thank you so much for your help with this.
And thanks for your patience with me plus really helping develop my knowledge on this topic.
It has been very much appreciated.

Thanks very much for clarifying Desertfox, much appreciated.
RB1957 no I certainly wasn’t questioning what Desertfox had written. I just wasn’t understanding it. My background is mechanical (more pressure containing) but I seldom carry out calculations and haven’t done any beam type...
Thanks again for the amazing support you have given on this. It’s been incredibly helpful and educational. And thanks for providing such detailed calculations that even I can just about follow.
@Desertfox… one thing I can’t follow is how you have calculated the bending moments per your...
Thanks a lot for your help with this everyone, its much appreciated.
It can’t lift using 2 separate lift points as it will be lifted by crane to a 5m plus elevation on the single lifting point at the top end and ran from the side of the vessel. It may be possible to support it though with...
Hello,
I was hoping to get some advice on how to calculate the strength of a new lifting interface. I have 2 existing tools that need to be joined together rigidly for lifting offshore. There are hydraulic lines between the 2 assemblies and access is also needed at the lifting interface for...
Thanks again for your help with this. So if I understand correctly I can just treat this as a simply supported beam. The crane is one support and the contact at the other end with the ground is the other support. Because the bolted interface is so close to the support any bending moment is...
Thanks a lot for the great advice. I see that it makes sense now that I was using the incorrect formula and treating the bolt like it was an 8mm beam. I have attached a sketch to better illustrate the lifting scenario. Basically the tool is third party and there is no option to change from...
I am trying to perform a simple bending stress calculation on a bolted flange interface but keep calculating a huge bending stress and can’t see where I am going wrong. Please can someone help?
I have a tool that is 2.9 metres long and weighs 250Kg. This has a bolted flange interface at the...
