i've always wondered how this could happen. Then, i realize that the pintle hooks appear to be generally bolted to the frame, not welded. (?) In a situation where the rear trailer----and then the dolly starts to go over, the bolts can't take that kind of stress start to shear off? And........over goes the trailer(?)

The latch on pintle hook above the eye usually gives up before the bolts.
I have never seen the bolts shear off yet.
The steel just behind the eye on dolly will also twist.Wrench97 Thanks this. -

Is that a doubles thing.
I never even heard the term. -

That said, I always pinned to standards even though I wasn't pre-tripping the set. Tug-tests, visuals on the pin locks, etc.
It could very well be a mechanical failure of a dolly letting go, which happens when you run junk.Mike2633 and blairandgretchen Thank this.
