Lifting Padeye on I-Beam
Lifting Padeye on I-Beam
(OP)
Hi All,
I am designing a structure with a final load of 25 tonnes. While I have designed lifting padeyes in the past where padeyes have been slotted through tubes (circular, square, and rectangular). This case is the padeye is to be welded on a I-Beam, but instead of just welding it with a full penetration weld on the upper flange, I want the padeye to be slotted to give it extra strength in the joint (welding on top and bottom flange).
1. Can you please advise what will be a better way to slot a padeye to the structure? There are 4 lifting padeyes in each corner.
2. Also, what effect will the welding joint have on the thin web of the I-beam when the 25 tonne structure is lifted?
3. Any other option where we can have redundancy in the padeye joint?
Attached picture for reference.
Thanks,

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

A purchased forged padeye will have an extended base that gives you more weld area to the top I-beam flange.
