The whole truck and trailer will disintegrate before a 3/4" shackle comes apart! Breaking strength somewhere close to 20tons X 2 shackles.
Look at the other parts of the trailer chain/ attachment system. Guessing it's not 3/4" cable and 1/2" plate connections.
Those shackles couldn't be more overkill. They'll work fine.
Agree the truck and trailer would be destroyed. I was looking at double the trailer weight which is about 11k and the shackles are rated at 20k
Perfect. Just look at the weakest link, figuratively or literally, in the safety chain system.
Those big ole shackles won't hurt anything, kinda like useful truck nutz hanging from the hitch.
And a 3/4" shackle is not rated for 20klb, it's rated for 4-3/4 tons if memory serves, but its yield strength is close to 40klbs. All "legal" rated rigging has a minimum 5:1 factor of safety.
