Lifting shackle bow nut bolt blue pin 13.5

[ethanhunt118]

Hi guys,

I was wondering if I have a shackle of pin diameter 39mm to be used on lifting equipment on construction sites, what sort of diameter would it require ? is there any guidance to that ?
At the moment I am using 41mm. is there a range of play allowed and safe ?

Thank you kindly
ethan

I use DNV 2.7-1 when designing pad eye (lift lugs). The spec is free.

I checked. DNV specs are copyrighted, but free.

Get the official versions by downloading the pdfs from dnv.com.

Should shackles be proof loaded after 4 years ?
