Subscription pricing is determined by: Hi JAE, Thanks for the reply. JAE, Still good advice, since I am doing the calcs in Mathcad to semi-automate the design, I am still going to check the section for it’s compactness, however there’s also a simplified clause for rectangular sections I will check out. In your case, I would see the b distance as the straight vertical edge to the base center of hole to base weld line.

I select the closest available Crosby G shackle for the load. Already Subscribed to this document.

We have no amendments or corrections for this standard. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

You’ll see that there is no criteria for checking whether the section is compact or non-compact. Almost invariably, pin bearing, shear and yielding in the area of the pin, and good quality welding detailing controls the design of lifting lugs.

Even then, I wonder about how much compression would even get into the lug with an angled hanging “tensile” load. Your Alert Profile lists the documents that will be monitored.

For a square plate, like your lug, local buckling is not possible. This standard is not included in any packages. I also need to determine this for a flexion analysis in the weak axis. For now, I am working on a single case and detailing the calculations.

You may delete a document from your Alert Profile at any time. The base of my lugs will be wider, however, to be conservative I am designing with a constant width plate for now. Join your peers on the Internet’s largest technical engineering professional community.

Students Click Here Join Us! Hi All, Thanks for your help. Their thickness is generally driven by byh checks on the pin hole that make this plate much much stockier than typical structural elements. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Defense manufacturing is all about project manufacturing and project accounting.

Download Now White Paper: We just recently designed some lifting lugs where the dimensions were pretty much set by the client.

Are you an Engineering professional? I’m not sure LTB of a lug could ever happen unless you had a really funky looking lugI would probably just use the full plastic capacity of the pad eye.


Hi Dik, That’s correct. It’s easy to join and it’s free.

The Eng-Tips staff will check this out and take appropriate action. The problem I have is that it’s not clear to me if I am dealing with a compact or non-compact section as per table Thanks again, of course further comment is always welcome.

The provisions in this Standard apply to the design or modification of below-the-hook lifting devices.

The next available drill size will be used to make the hole slightly larger than the pin. Therfore it is inherently compact. Please first log in with a verified email before subscribing to alerts. I think what I posted above is correct but WillisV and others posts are right on – buckling isn’t really an issue with lugs like this unless the plate is thin and the lug is really long and extended.
