This is why you always tug test with pictures.

I usually leave the landing gear about 2in off the ground before dropping but I always look to make sure. One truck has 11/24.5 and the other LP22.5, even letting all the air out of the tall truck I always have to do a few cranks so I don't high hook it. And I've high hooked it once before by about an inch and that few seconds to check will save your ###

 

At least it wasn't a reefer.

 

Don't forget the landing gear!

 

Might need a tug on the tractor.

 

It may need a tug, but it will probably be the best looking truck that wrecker has hooked to all day!

 

I probably wouldn't of attempted that. Or had someone spot me and see if I was gonna bottom out

 

He's putting a couple of electric valves to by-pass the front and rear leveling valves so he can raise it up.

 

I'm betting that it was a yard dog dropping those trailers. The chicken company I worked for where I got my CDL had one of their yard dogs with a sketchy 5th wheel. 2 of the yard drivers got written up for dropping a trailer. That was until the shop foreman was bringing a trailer from the trailer lot to the shop for a brake job with the same truck and dropped it crossways in the driveway. Come to find out, there was so much play in the worn out locking mechanism it didn't always lock fully, and bouncing around a rough parking lot would give it enough to unlock. They rebuilt the 5th wheel and removed the writeups from the other guys file...and the foreman never heard the end of it.

 

It's good to have a "system" or routine for everything in trucking. It helps make sure nothing is missed or forgotten. As long as it keeps you in order that's all that matters.
