Chain Grade

Boulders and concrete pipes, too, IIRC.

That is probably because section 9 of the FMCSA handbook (which covers vehicles under 10,000#) doesn't specifically mention tying down a boom: Driver's Handbook on Cargo Securement - Chapter 9: Automobiles, Light Trucks, and Vans | FMCSA
Section 10 (which covers vehicles and equipment over 10,000#) does specifically mention tying down a boom: Driver's Handbook on Cargo Securement - Chapter 1: Heavy Vehicles, Equipment, and Machinery | FMCSA
Good luck convincing a police officer on the side of the road that your loader doesn't need to be secured.

I am still trying to find someone who can show me where there are restrictions on what material your tiedowns are made of for securing equipment.
The ONLY restriction I can find is that crushed cars need to be tied down with chain or cable.

The WLL is the restriction. You may want to look through the rules rather than just the pamphlet. eCFR — Code of Federal Regulations
I think what youll eventually find is that any degradation in the securing system degrades the WLL. Any degradation of the WLL causes the whole load to be unsafe. A strap with a frayed or torn edge would no longer meet its WLL. You can argue the point of whether or not it is, but at what cost?

I didn't see it here, but Grade 70 chain has links stamped with the grade on it. Many lower grade chains do not, and do not require it. If the chains, hooks, binders etc do not have markings or permanent tags for the grade or WLL, the assumption of the lowest commercially available WLL applies.

I have a tool box on my trailer and keep 5/16 grade 70 chain, binders and hooks in there specifically to tie down the equipment. 3pt attachments get a labeled 2 inch strap each. Those straps and chains are for transport only. Its cheap insurance. Plus, who doesn't love chains?

Another often overlooked part is a grade 70 chain with lower rated hooks or binders is useless.

Some higher grade hoist chain is not grade-marked either.

Video of load tie-downs After 13:15 he talks about chain damage but really no mention of chain grade but I may have missed it.
