What is the difference between SWL and WLL in rigging for the film industry?

How did you find PF?

I came across the forum while searching for answers on the strengths of various items.

Hi there,

I am obviously new to the forum, but I am looking forward to being a part of the experience that exists here. Although, my knowledge of physics is more rudimentary than some members, my desire to learn new things is always prevalent. However, I do work in the world of Rigging for the film industry and know my way around this world very well, but there are always new problems to be tackled that the regular means of doing things won't work. This is how I found myself here... Everything we use has WLL stamped on them, and we have engineering schematics for so many items, yet I still would love to know more and I hope to find help here...

Thanks in advance!

Working Load Limit

It's an abbreviation stamped on thousands of items world wide to show the ratings of things like shackles, eye bolts etc. I didn't come up with it, but I apologize for assuming that people would be familiar with it.

Working Load Limit

Well, Have never seen it in Australia or New Zealand
the one usually seen is SWL ... Safe Working Load

I have seen SWL as many times as I have seen WLL. Well acquainted with both.
