Foundry hooks/J-Hooks

I actually haven't paid attention to the Grade of our binders, but they are Crosby/Lebus and the WLL matches or exceeds the chain.

 

That’s my point. If they don’t meet or exceed the wll of the chain then a higher grade chain is useless. I don’t see how using grade 80 is “cheaping” out. Grade 70 will do the job, you just may have to throw more chain. Which isn’t necessarily a bad thing. And one could make an argument that it’s better than throwing fewer higher grade chain.

 

That's true. On lighter loads like our 320, D6T, or 950K the grade 100's get us well over the threshold just using 4 main tie down chains and then 3/8 for the attachments or whatever sure seems to save time.

The one thing that I have noticed about grade 100 though is that we have never stretched a link on them. My grade 70s eventually all start to stretch, so from a cost perspective it may be less expensive to go with 80s/100s as they need not be replaced as often.

 

I agree with the stretch, but the flip side of that is the grade 100 are more brittle and will snap. Albeit it takes a lot more to do that. I’m not trying to argue one versus the other. Grade 100 definitely has some pros

 

Think my main argument as a pro for the high grade chain. Is if you get a machine that just doesn't have a lot of tie-down points it'd be a lot better to have the higher grade chain in that situation

 

But to counter that. What’s the rating of the lash ring or side rail of the trailer? I honestly have not idea what the rating is for a side rail. A 1” lash ring has a WLL of 15,5. Which a grade 100 1/2 is good for 15,000. So that should be fine. Depending on the welder too. But it would be pointless to use grade 120. Even G70 5/8 is 15,800.

 

I ain’t packing 5/8.

You've seen me. I'm an oooolld man!

 

Haha. Yeah I ain’t either. Maybe I will upgrade to G100 and drop down to 3/8. Everyone will say I’m an idiot chaining a 340 cat with 3/8.

 

He'll just use 5/16. You'll end up tying to mirror brackets, grab rails, and anything else handy just to get your WLL!

 

I went to 4 long chains that are grade 120 3/8” that are like a 1/3 pod the weight of grade 70 1/2” but have the 11,200 WLL - as an older guy with 2 bad shoulders - I think it was definitely the right move,

gonna build some 6’ ones next with grade 100 slip hooks - as I am not hauling anything particularly heavy right now.
