Wow, I dragged a lot of wagons, even rail vans, and I don't think I've ever seen one jump the holes like that. Those side clamps are supposed to prevent that. Must have been one heck of a bump,,like bounced over RR tracks empty?

Yeah, I've seen this a couple of times. Usually in my experience what happens is, someone would pull the old manual handle to slide the axles all the way forward on an empty trailer. Then forget to go back & release the handle & lock the pins. They get down the road going 40+ mph & come to a light or stop sign & hit the brakes. The tandoms lock up because there is no resistance & slam against the stops at the end of the rail. That causes the trailer to bow (or the tandoms to rock forward) enough that the retracted pins get above the rail while the shock (KABOOM) releases the manual handle, the pins release, now the pins are above the rail.
To fix this, you'd reverse the process in some regard. We'd take a fork lift etc & lift the trailer up high enough for the pins to clear the rail in which the pins were resting on, pull the handle to retract the pins, lower the trailer & release the handle to lock the pin in the rails.
Its a pretty easy/simple process once you've seen it done. -

i only have seen pics of say a rear-ended trailer, where the tandems are knocked out from under the trailer. -
Yep, made a bunch of calls for that. Always because the slider handle was left out, or pins weren't locked in. First time brakes are hit hard, all the way to the back it goes, jumps and sits on the pins above the cleats.
I always supported the back of the trailer with jacks, removed the cleats, dumped the air bags, then lowered the jacks.
And installed new cleatsMagoo1968, Flat Earth Trucker, buddyd157 and 1 other person Thank this. -
Weird how many of you have never seen this. We probably get 1 or 2 calls a month for this, not a crazy amount, but definitely not uncommon for us.
Lonesome, Flat Earth Trucker and 062 Thank this. -
These two repairmen were experienced professionals. Everything was put in place just as it should be.
The_vett Thanks this.
