49 CFR 393.120 - What are the rules for securing metal coils?

"
(ii) At least one tiedown through its eye, restricting against forward motion, and whenever practicable, making an angle no more than 45 degrees with the floor of the vehicle or intermodal container when viewed from the side of the vehicle or container; and

(iii) At least one tiedownthrough its eye, restricting against rearward motion, and whenever practicable, making an angle no more than 45 degrees with the floor of the vehicle or intermodal container when viewed from the side of the vehicle or container."

Those chains are closer to 80 degrees I would say.

 

One thing all of you are overlooking , two flimsy coil racks on a coil that size should have a minimum of four.

 

10,000 lbs a piece.

 

Coils R Us?

 

I would say the regs are minimal and generally lacking.

A coil would have to move up to get over the "bunk" before it could go forward. An angled chain isn't going to do as much to prevent that as a "straight" chain would. When they use a crane to lift a coil they don't use a spreader so the chains can come in at an angle, it makes them too weak.

It seems to me you would be trading two tiedowns for one when putting them at an angle.

Not to mention the angle of the chain between the eye and the deck.

Which brings up another question...
A 30 degree angle like the example on the far right renders the "tiedown" at 50% of it's strength. When when we throw chains on a coil do we take that into account or just figure the chain as 100% WLL? Maybe when we think we have 100% of cargo weight covered by tiedowns maybe we really only have 50%.

 

And anything over 45° is the regs, so no 30°. You went the wrong way. If you actually look at the way the angles are the only part at anything but around 90 is where they hook and most use teardrops so it wouldn't count the same.

 

Heh, I was talking about a different angle. The angle of the chain from the eye of the coil to the tiedown point on the trailer, looking at it from the front of the coil. The further away the tidedown point is from the coil the weaker the chain will become. I just guessd 30 as it would reduce the rating of the chain by 50%.

Can we throw a chain like that and still figure it for 100% WLL when trying to figure out aggregate WLL , to see if we are within regs? Just a question just to question thngs.
