Securing Large Coils

LOL, yeah, you know.
The small 'bubble of reality' when driving doesn't extend that far.

 

Since you are from Mississippi, next time you get to the big Black River on 55 headed southbound MM129, look in the median. You will notice a lot of damage there in the median just north of the bridge, a Freightliner Coronado went into the middle and laid over. He had no headache rack, the suicide coil came loose and flattened that truck completely and he died instantly.

 

That's pretty fast. Even for me. I was processing the nearterm gore that is fixing to come out of that crushed can. And it's stopped. Nice.

I WONDER though... that video must have been sped up just a tad...

 

GPS said "turn left now"

 

The scientific term is “braindead.”

 

There’s not DOT rule that says 10,000 per chain.

 

They taught you what..?

 

It depends on a lot of things. As far as WLL, 3/8" grade 70 chain has a WLL of 6600, this is probably the strongest piece of your 'chain,' the binder will have its WLL embossed on it, I've found these to be the weakest link in the 'chain', as most that I have and have seen are rated at 5500, some even less.
Then get the trailer owners manual and determine what the WLL of the possible chain attach points are; stake pockets are useful on a lot of trailers, the gunnels (pieces welded between the rub rail and the chassis) are possible candidates while the rubrail itself is generally not a useful point for chaining, again this is up to the manufacturer. The lowest value is what the WLL of that 'chain' is. In my case the binders are the weak link, so while my 3/8 grade 70 chain is worth 6600 I still have to put the crappy binder on it making the whole thing worth only 5500, you are able to use the full value since your chain will be going over or through the object you are securing.

Then get you a book on securement(mines called 'practical cargo securement IBSN 0-9680607-9-X)
If it were my 40K suicide coil, I would use 3 pulling forward and 3 pulling aft which in my case would be 33000 and well over the minimum(20K) and well within my comfort zone.

Good luck!

Edit: Duh! my pockets are 5400 so my crappy binders aren't as bad as I thought and the aggregate WLL would be 32400 and still confortable for me.

 

^^^ This is exactly right ^^^

I also use 3/8” G70 chain with a WLL of 6,600 pounds, but on my Fontaine step deck all of the securement points are rated at 5,400 so that’s the max I can get out of an indirect chain tiedown, or 2,700 pounds from a direct tiedown.
