65k, 4 chains, good to go

Hmm...if you are talking about using two ends of the chain and securing points. Then two binders as the other two points. This would count as two chains in my mind. Doubling a chain with one binder will count as one.

 

A grey area? If it was my own personal machine. I'd do the above and call it a day.

 

I wouldn't think you would be required to remove the propane tank since it is the machines fuel supply. The extra tank, not sure how they would look at it, but it appears to be plumbed in with the other tank?

 

Most of the ones I’ve ever seen have the two steel straps that kinda snap Ober center to hold them in. I’ve hauled plenty of forklifts and man lifts that have propane tanks without a problem.

That’s still considered a direct tiedown so you get 50% credit for the chain. 3/8” grade 70 like that is good for 3300 pounds.

They do not make it divisible don’t worry about it. Just make sure they are secure.

 

the tanks properly secured (caged/locked down) are part of the load, if easily movable they are NOT part of the load.
the picture below will give you enough tie-downs with 3/8 gr70 to cover a 66000# load. 8 at 3300# and one at 6600# totaling 33000# (50% of 66000)

 

Anything that renders the machine incapable of performing its intended task makes it non divisible.

 

Since you own it, Just weld D rings on it wherever they line up the best with the ones on your trailer.
Cross chain front and back. And at least one on the side higher up, so that you got room to work.
Make up some short 1/2" chains just the right length.
Then paint em titty pink so they don't wander off...

 

This is probably the best answer you’ll get, just make your own securement points.

 

Midship(where it articulates) is always a great spot to chain down. It’s also the law/good idea to lock the mid ship in place. Most articulating machinery will have a bar you can put a pin in.
