Aluminum Flatbed Trailers

I used to re arch my old 1981 alumium dorsey flatbed this way. Put a single37000 lb coil in the nose and put a 40000 lb single on the rear then unhook from it and let it sit all weekend. That was when I was a steel hauler. That old trailer almost never left Chicago or Baltimore with less than 75000 on it.

 

Steel trailers have an arch as well, just not as much. My Fontaine steel step has an arch on the bottom deck.

 

DO what now? how does putting 2 coils on both ends, re arch the trailer?

 

If you do this thing with the coils at the same time you dump several gallons of potions into the crank while leaving the truck running with a 90 pound weight on the service pedal, you'd be surprised. Not only will your engine last forever and your brakes always be adjusted, but your trailer will be re-cambered.

 

Any body got any info on alutrec tier aluminum flats? are they just log trailers? Tried a google search, but no luck.

 

Sorry I am totally lost on this concept.

 

When i was hauling heavy this is what I would tell people I am re arching my trailer I never actually pulled out from under it completely with that kinda weight on it
.

 

i never pulled out from under a loaded flat when i was hauling (heavy). the only thing on my mind was to hurry up and get that heavy load off so i could go and get another (heavy) load!!

 

Several years ago I did have one of my trailers re-arched, basically they tied down both ends of the trailer, then put a huge hoist over the area to be "arched", after they got the arch they wanted (or actually slightly more) they took the welder, while under pressure and re-welded the bead on the main bean in a couple of sections.

It worked and we never had another problem, don't know if that is how they ALL do it, but that is how they did mine.
