I've ran across the 80% thing somewhere but I'm having trouble finding it right now, I'm sure someone will post it for us. If that 320 weighs 64,000 that would be the heaviest 320 I've ever seen, but we'll use that number. You need 50% of that 64,000 so 32,000. Your tiedowns that I can see are direct ties downs so you get 50% of the WLL for them. I'm assuming you have one hooked on one side of the bed running over the stick and fastened on the other side, that's an indirect tiedown so you get 100% for that one. Now that machine weighs over 10,000 so you need a minimum of 4 tiedowns, the stick needs to be independently tied down (which I think you did). If your chain and binders are rated at 16,000 and you have them fastened like you do you would get 50% credit for those as direct. tiedowns. if you had 4 16,000 pound chains/binders that's 16,000 X 4 = 64,000 X 50% + 32,000. I don't know what you have over the stick, I use a 3/8 grade 7 which is good for 6600 so I'll use that. You get 100% of that because of the indirect thing. so 32,000 + 6600 =38,600 which covers your 32,000 requirement. We didn't used to have to think about this stuff until a few years ago and it still doesn't occupy mush of my time. I can tell you this I have been through countless scales, inspections and superload pretrip inspections and I have had my hand slapped for not having not having enough securement but I've NEVER had any type of law enforecemant bring up the 80% pulling rearward thing so I wouldn't sweat it.

 

I just did a new 329F and it was 68k. So I dont think he is far off.

Question,.. I'm familiar with 3/8 and 7/16 chain ratings. What would the WLL rating be for 1/2 inch chain be? Are there different grades of 1/2 inch chain. How would I determine what I have?

We use 1/2 inch chains and its the binders that are the lower number, which are rated at 15 988

 

Thank you.

I dont have any use for 1/2 inch with my step deck. Nothing I have on my trailer to hook it to is rated more than 6600 lbs except my stake pockets which are rated 7800.

So now dealing with heavy haul and the capacity that this set up is capable of, I'm out of my league and trying to have a crash course understanding it all.

Mad respect for you guys. Money is good even as a company driver. Carrier is trying to wine and dine me into this. I just dont think this is for me. I miss my little step deck combo.

1/2" chain grade 70 is rated at 9900 pounds. I had a friend of mine that moves containers tell me that 5/16 chain was rated for 16k. I laughed at him and told him to go read again. I think he was looking at the breaking limit not the WLL.

 

Thats crazy,.. the chain hooks in my step deck are only 3/8 and rated 6600 lbs. I have four 5/16 chains that I use for smaller stuff,.. like that little 1600 lb tug tractor from the air port I hauled. I used 2 chains,.. but had them set up with 4 independent points of contact with 4 binders because I wasnt sure of the rules,.. so felt best to just use 4 points.

 

I forget what's the wll of grade 120 5/16 7500#? But dang they cost a fortune!

 

A 329 is a fair amount bigger, Cat lists the 329 at 69,000 and the 320 at 54,000 most older 320's I've hauled were in the low 50's they are a 20 metric ton class machine similar to a 200 Komastsu or Hitachi that size excavator is a common utility tail machine in my area and I've hauled many of them. If memory serves a 1/2" grade 7 chain is good for 11,300. They should have a marking somewhere, take a wire brush and check some links every link won't be marked but some will look for a number 7.
