Heavy Haul Securement Advise

OK, you mentioned chain drops on a double drop and then having to remove hooks on one end to use it, so you must be talking about the chain slots that are cut out on the outer beam flanges. One thing is you do not have to remove the hooks. Just feed the chain into the hole with the hook left outside and the link will slide into the slot. Most of the chain slots will take a 3/8" and 1/2", but keep in mind the chain slots are rated for around 8,500# each, so using a 1/2" chain is a waste. The D-rings are good for about 15,000# each straight line pull, so you also have to think twice if the chain is at an angle with the D-ring. Leaves you hooking top the top flange or through the lightening holes in the web, but off the top of my head I ca not remember the rating which depends on the flange thickness

 

When you start having to deal with 1/2" chain, long sections can get really heavy. Most of the time you don't need a very long chain to secure construction equipment and whatnot. I've even got 4- 3/8 chains 6' long slip hook/grab hook combo that has proven to be very handy.

 

I just use two chains at that point to cross chain. But I use 1/2 so I try not to bust out my longer chains that much

 

You won't find it because it doesn't exist, if your instructor said it did he was wrong too.

 

For the most part I think cross chaining is unnecessary. Occasionally it's the best way but not often in my experience. It seems to give a false sense of security.

 

Yes.
