Yup, looks good. I would add wire to the boomers and call it good.
I like my boomers facing up when closed and when closing them. But some of the bigger guys have no prob. a little side ways.
As far as the chain doubled back, normaly I would use that when chaining iron as there is not much give. So when you take a link it realy is only half a link. muzy
Next Question, Median barrier.How would you tie it down ? I gotta haul a couple of loads tomorrow. Precast concrete 12 feet long and around 6600 lbs.

I am in agreement with Digger242. I do NOT cross chain EXCEPT when the tire on the equipment does not allow the chain to run straight from the tie down on the machine to the D-ring or chain slot on my trailer.
I try to keep the distance from the tie down on the machine to the trailer as short as reasonably possible. When standing at the back of the trailer looking forward, I like to have chains as close to vertical as possible. When looking at the trailer from the side, I like to have the chains angles somewhere between 45 and 60 degrees. I haul lots of sprayers and combines, which are wider than the main deck on my trailer, making vertical chaining possible.
The D-rings on my trailer are rated for 7500 lbs and the chain slots are rated for 8000 lbs. I usually use the slots whenever possible. Grade 70 5/16" chain is heavy enough for most things I haul--if something is heavier, I use more chains.
We recently had a DOT officer put on a training seminar for our company. The way he explained chaining, if the chain leaves a tie-down, goes through a loop on the machine, and returns to the original tie down point, you can figure the whole weight rating of the chain. If the chain does not go to the same tie down point, it only counts for half of it's capacity. In this picture, if I understand the rules correctly, the chains could only count for half of their rated capacity.
I will try to remember to get some pictures of how I chain things down, now that I have a phone with a camera that works.
As for the barrier it will depend how they are being loaded and unloaded. Forklift they have to be on dunage, crane-on the deck. as far as securement they suck as most are smooth with no tie points. If they had liftting points, run chain thru from one side to the other. If not then a piece of dunage chained down in front to limit forward movment incase of emerg. stop.
Probly would end up with 2 over the top (chain or belt) one across the front pulling back, one on the back pulling forward (chain) per. group. Maby a third over the top. I think with these it would be hard to get 2 differnt scales to agree. good luck, but you have hauled more loads of these than you could remember. I am confidant what you have been doing will make the grade. muzy
Here you go Tiny. Do you think this guy has this load properly secured?
Deerhuler, I understand what you are saying, but am in disagrement with the dot officers interpitaion.

If will look at how lifting is done we see that rigging has diferent working load limits depending how it is used.
If we use 2 diferent anchor points for the same chain, we have created a basket. So in my opinion that would also increse woking load limit of that device by 2.
I have been challanged by dot and have had discusion on this method. No warning or ticket issued.
I would not argue that it would give twice the holding capacity but would be confedent at 1/2 the capacity ei- 1000 lbs increse to 1500lbs. muzy

Tiny,
Tying down barrier is as easy as it gets. Depending on your preference 3,4,5,6 Chains however many you want just thrown across them and tightened down. That's all I and all the other guys at the precast company did. We placed them lengthwise and we had 10 footers and we did 10 on a truck, 3 over the drivers, 3 over the trailer wheels and 4 in the center. I'd figure what 8 or 9 on yours?
There's a difference between reading and comprehension.
Reading means just that you read it and when you answer it'll probably make no sense.
Comprehension means you actually understood what it said and when you answer it'll probably be on subject.
like this with the chains going thru the holes in the jersey barrier (shown in green)

Just the way it is right now is how I'd do it, I'd have one more chain on it across the top but that would be it. 3/8" chain and snap binders.Originally Posted by tonka

Ok... back to the fork lift,I tried it that way and it didn't feel right.Next time it will be crossed Lol. also wanted to see how much I can over tighten one corner that way (last pic) .....Never had a problem getting chains tight.

Now for the barrier , Neither Missouri or Kansas barrier have hole in them like shown but to be honest I wish they did.So this is what i have been doing and never had a cop even look twice at it.
I had a lowboy tractor so only 8 pieces at a time 3 , 3 and 2 . Used all but two short chains , All the lowboys have their own 1/2 inch chains on them so this lowboy truck only get 10 chains .

Tiny, you chained the forklift almost exactly how I chain 90% of what I haul.
On newer John Deere tractors the chain points are big loops cast into the mechanical front wheel drive axle. On tractors with Independent Front Suspension, the chain points are on the lower A-arms. On these tractors I will cross chain the front of the tractor so the tire does not touch the chain. The forklift in the first picture has tie-downs far forward enough to make cross chaining unnecessary, in my opinion.
I agree with Deerehauler.Thats how we secure our equipment. We had a trailer come unhooked from a truck (long story) with a roller on it. The roller was secured in this manner with 4 individual chains. Trailer went in the ditch on its side but the roller stayed on the trailer. I might be able to find a picture of that..
