Reusable Bolts For Lifting Lug
Reusable Bolts For Lifting Lug
(OP)
I am designing lifting “trunnions“ bolted to skid base. Skid will be loaded and unloaded several times during shipment and therefore these trunnions will be also bolted and unbolted several times. I would like to use the same bolts. In this case which bolts should be specified?
Thanks in advance,

What is the total load? How will the bolting be loaded,tension,shear,or a combination of both?
I think this type design is inherently dangerous. I've seen a load fall due the substitution of bolts used on bolt on lifting lugs.

I am not aware of any published guidelines on this, although chapter 1 of Parmley's "Standard Handbook of Fastening and Joining" touches upon the subject. Aside from the above, another good reference is Blake's "What Every Engineer Should Know About THreaded Fasteners", although it doesn't seem to address your question.
