We just recently designed some lifting lugs where the dimensions were pretty much set by the client. Alternatively, I will survive without see it. This standard is not included in any packages. That is the governing provision for square plates.

For now, I am working on a single case and detailing the calculations. Subscription pricing is determined by: Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. 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 also need to determine this for a flexion analysis in the weak axis.

As the voice of the U. Back-calculate a t required to ensure a compact behavior and you go from there.

Your force diagram assumes that the pin dia and the pin hole dia are the same 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 Instead, you’re checking for a glocal buckling Lateral torsion buckling mode of the plate.

Hi Everyone, Baseed on thread The Eng-Tips staff will check this out and take appropriate action. Download Now White Paper: I have never seen a lifting lug that would not be classified as compact by a long shot.

Therfore it is inherently compact. Any help would be appreciated. The lug is as per figure C It’s easy to join and it’s free.

For a square plate, like your lug, local buckling is bh possible. If the document is revised or amended, you will be notified by email.

Usually the “b” is the length of the free, unstiffened edge which undergoes compression. The provisions in this Standard apply to the design or modification of below-the-hook lifting devices.

Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

The base of my lugs will be wider, however, to be conservative I am designing with a constant width plate for now. Your Alert Profile lists the documents that will be monitored.


I think some of you above need a thanks from me – getting my head out of the sand. Are you an Engineering professional?

Provides minimum structural and mechanical design and electrical component selection criteria for ASME B You’ll see that there is no criteria for checking whether the section is compact or non-compact.

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 bfh. Even then, I wonder about how much compression would even get into the lug with an angled hanging “tensile” load. We have no amendments or corrections for this standard.

I have also attached a sketch. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. 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.
