I'll tell you what!!! Has anybody seen the big truck trailers with the tilting landing pads on jacks? They ride in a low in the rear attitude and look B.A. to me. The 12 thousand pound axles from Dexter are $1300 each through my dealer in TX. Two month waiting time after ordering... Tires and wheels are $235 each and are 18 ply rated at 6005 lbs each. Though they are 17.5 inch, they are actually smaller in circumference than the 16's. (lower profile side wall) The total will be around $4000. to get to the labor part. Meanwhile I'm looking for the big truck jacks I've got to have, these Bulldogs are petty in comparison., comparatively the Bulldogs look anorexic...
Talking to my engineering friend, we agree there is no rating that can be put on my mainframe and bedframe because there is no comparison, the weight carrying capacity of my trailer can *ONLY* be limited by the axles. The diamond plate is 278 lbs per sheet, times 5 equals 1390 lbs...

I was thinking of putting JDM inside neck I-beam and now I'm toying with maybe:

LEVIATHAN
BEHEMOTH
COLOSSUS
DREADNOUGHT

Heh!

Maybe DREADNOUGHT and my phone number...

Anybody have a set of big truck trailer jacks that sound like what I'm talking about please contact me... I don't believe they are made any longer, too much weight...

Another comment on commercial trailers... Folks the entire "torque tube" fiasco created by the large trailer companies to sound intelligent and add cost is killing me really, I get tears streaming down my face at the lengths they will go to in order to build a cheap trailer and make cheap sound inviting. Hilarious doesn't quite get there...

So as I mentioned in an earlier post, get up on a commercially available trailer and walk to any corner and jump and the opposing corner flops up and down, well looky here people... Along comes the almighty *torque tube* watch this; by welding a piece of pipe at 2 or 3 points inside the mainframe they can cut down on the flopping when you jump on the corners... Hehehehehehe....

Okay, here's the thing people... steel flex is about the worst thing you can do to steel, it causes the steel to become stressed, metal fatigue is a serious problem, you cannot fix it. Imagine replacing the main beams in these trailers after a few years...

Again, I'd like to point out that anybody can build their own. My fully boxed mainframe beams are extremely ridged, the rear wall of the 6 inch channel is 7/16 inch thick, the web is 3/4 inch, now double that and you can imagine the strength we're talking about. Two of those for the main frame and then main frame crossmembers from the same material, then add another one to the center of the crossmembers... Do you think this system can flex???
