The Truckers’ Report flatbed Hall of Shame.

Let's do the math. √(138^2+51^2) = just over 9 inches decrease in clearance to the cab in the turn. That is, of course, if the load is all the way to the edge of a 102" trailer and 10' overhang on an 18" kingpin.

 

Math with letters gives me headaches.
Crank it off to a 45 and get out the tape measure. The taller the load and head rack/sleeper the more extra inches you need going through dips.
Oversize overhang is no different. Hang the tape parallel to the trailer the same distance the load overhangs.

 

I could make a quick calculator in php if you want. Just go to a web page and enter the numbers. I've been looking for something to do and those are typically pretty easy projects.

 

I see what you are saying, but the overhang does not move that much. The only trailer I have owned with an 18 in kingpin was a stepdeck, with 3 foot pullouts on the front for hauling vehicles, I barely had room on my international to put a vehicle up there and never touched anything.

I used to pull a live bottom, open top van that had a deep king pin setting and a catwalk on the front of it. I had a short, too short old A model, and had no choice but to take the headache rack off to even hook up. It would and did get into the sleeper when on an incline, or crossing a ditch, but on flat ground we were fine.

 

Saw this one the other day.....
Yea wtf dude...

 

Whats wrong with it

 

Look at it. Multiple sizes, only putting force on the top pieces. I saw pieces bouncing on all of the lower levels as he was going across the lot.

 

LOL wow , im not even sure how i would secure that mess but it would definatly be with more than 5 chains. But technically it looks legal, if its 40ft or less, 5 chains will cover length and weight . but yeah i see what u mean now, looks like a accident waiting to happen. Hes 1 hard break from hanging his head on the end of that steel

 

That's why I absolutely hate doing structural prefab. The loader only cares that it all fits on the trailer. Not if it'll be securable.
