Is this ok? (chaining)

Nope. I'll let someone else explain more, but there's nothing keeping it from walking off a side.

 

No, 4 tie downs required over 10,000lbs.

You only have 10k of a 16k piece of equipment. If your chains WLL is less than 5k each, you need more than 4 chains, or the equivalent to match that 16k piece of equipment.

I’m assuming you have it like that in all 4 corners of each backhoe. I can’t tell on my phone but it appears that the chain is pulling on itself..... in other words it’s not attached to anything on the trailer.....

 

You can use a single chain but you must have 4 separate binders.... 1 at each corner

 

KInda.

You have absolutely nothing to stop it from coming off the deck to the side.

I see that you have run what appears to be a nice long chain across the deck to the other corner with a binder on it. I would add two or three more on all 4 corners.

I used to haul a ford F550 backhoe and what we did was wrap the outside axle shrouding on the front end many times and then bound it to the trailer below. 4 different ways. It's not going anywhere on that end. The backhoe end however... we put whatever we can put on there. And generally had no trouble because of how the trailer is built, it really had no place to "Work loose" all chains have a loop designed to keep adding pull on itself if something tried to pull away. Makes sense?

Theoratically God can pick up the whole thing and flip it upside down and it should stay on the deck. Should being the operative word because any link is a failure point on any one chain. That's why you add two three or four more.

 

You can do the welded stake pocket.

But DO NOT put anything at all on that outside rub rail. It absolutely WILL NOT HOLD. There was a way of looping the chain hook from the bottom of the stake pocket inside up top, wrap once and hook up top so that gravity will hold it there barring anything else. Follow the chain back to whatever you are securing.

What you can do is put one binder hook onto the object being secured and use the excess chain with a extra binder to create a sort of a failsafe.

Im one of those people who are paranoid about securement, I put on everything I possess and build in where possible two or more chain that does nothing but act as a fail safe. (This includes straps.)

I have no formal training in chain working strengths or straps 4 inch wide strength. All I know is that 4000 pounds is a good number and you multiply chain until it's possible for God to pick up the whole thing and it's going to stay secured.

 

Yes... put chain on the machine and run binder from stake pocket to looped chain that’s on the machine. Do the same on all 4 corners and the slack of the chain will be in the center....
