this is a great thread. It is good to hear all the different discussion. You can never have enough safety reminders or talk.
Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
On the chain connection thing(outside the pocket or rails), does anyone have a resource the shows that in writing(dot rules). I have heard that from several people, but never seen it in the rules. Never had an issue on the road with it either.

You asked it was true anywhere........
I'm in the rigging business also and this info is wrong about why cranes use a spreader beam. As you can see in the pic of the post, without a spreader beam the rigging would damage the load because the angles will cause the rigging to pull into the load. This is the sole purpose of a spreader beam (to clear the load being lifted when the attachment points are at the corners of the load). Using a spreader beam actually increases the load on the rigging. While the lines coming off the bottom of the rigging are at 90deg, The lines going from the beam to the hook are actually much greater than if no beam was used.Take for instace heavy lift crane operations. Often times you will see a "spreader bar" in use. This is used to reduce the angle of the rigging above the load in order to ensure angles as close to 90 as possible.
Crossing your chains reduces the capacity of your chains. It's simple physics (if there is such a thing).
As far as I know the lever type is still legal. Our insurance company doesn't like them though. We were urged by them to swap over to the screw type but it was just a suggestion. We have some screw type but still use the lever type mostly.I've also heard that loadbinders need to be screw type and not cam over/lever type. Is that true anywhere?
