Figuring WLL and trailer securement points

I don’t strap over the boom on them. I strap or chain the cage, but never throw a strap over the boom.

 

I think JD addressed this:

 

I see this. I wonder why I was told this. I knew him really well and never had a issue. He is retired and hell I miss him. He was a pretty good man. Now he would do his job when you forced him too. Or didn't speak english. The rest of these twits have a personality of a thumb tack.

 

Somewhere in the back of my mind I had the same impression.

 

I wish I could thank this 10 times.

If one could secure a coil that way, and all chains were u as opposed to x, that securement is worth 149,200 lbs, or 6 times over what is required. And in other words, if securing a coil takes 15 minutes, it would take an hour and a half for him to secure a load!

No wonder he had to drive cabovers 140 mph!

 

I always throw one additional chain on these coils to prevent it coming forward, and I X 2 straps over the top to 4 J plates.
Yes, it’s more than I need, but the extra 10 minutes increases my chances of going home.
As for loaders, 2 chains, 2 binders on the front of the machine, one chain and 2 binders on the rear, one chain 2 binders in the center.

 

That only makes sense. 52,000 lb coil, which, btw is rare because many cranes have a 50,000 lb limit, would need 6 tie downs. Throw on an extra one or two, certainly is better than leaving 1 or 2 off. But to throw on 32 extra tie downs?

 

That’s one binder and 2 portables

 

For the op, direct method and indirect securing to the same side, the WLL is 50% of the rated WLL. Indirect, securing to the other side is 100% of WLL.

So for me, hauling coils shotgun, one pair x chains is 13,400 lbs, 2 u chains are another 6,700 lbs and a strap over the top is 5,400 for a total of 25,500 lbs, which for my carrier is sufficient under 40,000 lbs and is 5,500 more than is required by FMCSA. Above 40,000, then either 2 more u chains for 6,700 lbs or 2 straps over the top for an additional 10,400 lbs.

Let's say instead of a coil, you were securing a 20,000 truck. 4 chains at the corner for 26,800 times 50% is an aggregate WLL of 13,400. Enough for the 20,000 lb truck, but my guess is the guys who haul that kind of stuff regularly would throw 2 more chains on.
