Thank you, everyone.
As soon as I saw the front of the trailer lift in a way it was not supposed to, I let go of the trolley and slammed the brakes. Which caused the trailer sort of "pop" up, and over to the side. I was told that one of the other drivers kept rolling, and they had 2 runaway spools as a result. Neek, a nightmare realized, but I will be even more vigilant about things. I cannot wait to get my SSD, and then I will be be married to just that one trailer, all the time. I mentioned in another thread I prefer live loads Now I have another reason to prefer them!
Grumpy, my best guess is that my 5th wheel locking mechanism wasn't fully engaged. Doing the tug test, and then the trolley test, it must have re-opened.
Marc, see what you're missing out on? 😁
One time I did a tug test like always. Tugged twice like always and it seemded good. Got out secured my whole load and raised the landing gear. I got back in the truck and started it up. Then I was about to pull out and thought man I forgot to check the locking jaws and the handle. I looked under and the handles wasn’t in all the way. I then looked at the jaws and they wansnt closed all the way. Close but no cigar. I had to put the landing gear back down and start over. That would have been the end of me.
Truck drivers who regularly pick up from or deliver to the shipping ports will often be required to carry a TWIC card.
Your TWIC is a tamper-resistant biometric card which acts as both your identification in secure areas, as well as an indicator of you having passed the necessary security clearance. TWIC cards are valid for five years. The issuance of TWIC cards is overseen by the Transportation Security Administration and the Department of Homeland Security.
Thank you for sharing! Even though I check and double check, I'm always nervous pulling away after hooking to a trailer. I really, really like that I don't have to switch trailers anymore. This one stays with me.
If you've ever looked at a king pin close, you've probably noticed that there's an indentation where the bar, or jaws lock across. Always make certain the king pin is seated so that bar, or jaws actually fit into that indent, because otherwise it's not hooked correctly, ... even though it may look like it is,. .and one good pothole can pop it out, and the trailer separates from the tractor while you're rolling down the highway.
My guess is that because of how that trailer was situated, you didn't get a snug fit, even though it seemed to be locked in. I agree with asking a hostler to pull a trailer out when it's sitting so poorly. But then, I'm not big on risks lol.
So glad it wasn't worse. Great hook procedure!

What is weird is he did a tug test, and it held.
