Anytime you get in and out of the truck, check to make sure your release handle wasn't pulled. Also when doing a drop&hook, a "tug" test isn't enough, you have look and make sure the jaws are locked on the kingpin. Been seeing this more and more lately. Very dangerous.
Why would someone release it ?! ...plain stupid in my opinion ... I honestly check it only when I'm leaving my yard . Will pay attention !
I've seen trucks in rest areas and truck stops that didn't check and the trailer nose is on the ground. One driver was lucky and another driver had his forward facing camera on and saw who pulled his king pin lock. He warned the driver before he got back in his truck. They caught the guy that did it are reported it to the police and his company. Don't know what happened after that.
Do you think it’s pins being pulled or more of a guy hooking up to a heavy loaded trailer and it’s been just hanging on by weight? Ive seen dropped trailers many miles away from any possible place to have had it purposely pulled I never set my trailer brakes and I think in most cases that also helps in making it difficult to pull
Always check it but then again I don’t go out of my way to piss people off. generally only ******have stuff like this done to them and only ****** do it to people.
I used to put some pressure against it for the night. set trailer then wait a bit, then snug the lock up tight and set tractor
