Hi Folks,

I am unsure as to what weight I should stamp a S.W.L. on a pad-eye.

It is designed to hold a dead weight of 5 tonnes however when addition factors are added (skew loads, dynamic loads etc.) this rises to 8.76 tonnes. I'm not sure whether I should have the former or the latter stamped on the pad-eye. Officially the SWL is 8.76 tonnes but I don't want a crane operator to think that they can lift 8.76 tonnes dead weight.

Perhaps I should be stating a SWL and a rated capacity or something similar.

Any thoughts or advice would be greatly appreciated!

Ian

if it designed fOr 5T SWL, and tested to overload as per regulations], it should be stamped to 5T.

I am confused is the 5 tons or 8.75 tons the safe working load? did you design and manufacture the padeye? Where is the padeye going to be used? show us a sketch of the item because the term padeye is misused too often.

Hi Folks,

Thanks for the responses.

Chicopee, I think I am confused also!

Is this making any more sense?

Cheers,

Ian

Hi smithson1984

If the safe working load is 5T then that is the safe load it can lift period, the 5T in my opinion includes skew factors, wind etc.

As desertfox stated the SWLs are determined by applying factors of safety to the braking loads. Your padeye is to be marked 5 tonnes. With a dead weight of 8.76 tonnes, the number of 5 tonnes padeyes will depend on their arrangement to the dead weight.

What load has it been tested for??

Hey guys,

Thanks for the responses. It's greatly appreciated.

We pull tested each pad-eye (of four) to 15 tonnes which was essentially the 8.76 tonnes with a 1.75 safety factor on top.

Cheers,

Ian
