1st time situation since I've been driving.

To answer your question. Yes this does happen a lot in my part of the country, do not feel bad, it is not your fault.

 

So the OP is saying the landing gear just fell down ?

 

I have had a lot of drop and hooks and hurt my shoulder bad lowering landing gear. I dealt with good and crappy trailers. I have never had landing gear just slide down on it's on.

 

I've seen some RR junk where one dolly leg was grinding on the pavement, I think it even happened to me. The landing gear was stripped or broke inside, and the leg fell. I don't think both would drop at the same time. I think you'd know in 5 feet if your dolly's weren't up. I suppose it could happen, both falling.

 

Pa parkway is actually in Indiana

 

My guess is that after the landing got hung up and ripped off that the company sent the "Maintainence man" out to fix the situation and the guy told the company that they were cranked all the way in the up position.

 

So.. the actual bolts that hold the landing gear to bottom of trailer broke/were missing???

 

All the way up.

 

I'm surprised they don't put plastic pylon sticks up around those edges of scale to keep that from happening.

 

You shouldn't have to.
