Beefing up a sand rail trailer. To haul my blazer...

[Copenhagen]

Ok heres what i have... I bought this trailer from a guy that was hauling a sandrail... Obviously i need to beef this thing up to haul my 5500# blazer..

The trailer was built out of 4 inch C channel for the main frame rails, front, back, and sides... it looks to be 3/16" thick.

The cross members are 2-1/2 x 2-1/2 angle iron 1/8" thick... There are 8 crossmembers

The trailer is 14' long and 8' wide

My tires ride directly on the frame rails, so i think i can get away with the crossmembers that are already on there, as most of my weight is resting on the frame rails..

I was thinking of just welding 4x2 .180 wall rectangle tube to the outside of the frame. Basically just wrapping the exsisting frame rails.

So my question is, Will this be enough?... and Could i go even smaller and maybe use .125 wall rectangle tube for this? Saving money is nice, but if you guys dont think it would be safe, then i would just go with the .180 wall...

thx for the input..

If it has dual 3500 lb axles you are going to be close to maxing them out.

axles look to be trailer home axles...

when you say close to maxing them out.. your talking about the weight im adding to the trailer?..

im assuming if i search.. ill find info on what trailer home axles are rated...

looks like my axles are good to go.. after i go through em and make sure everything is tits...

So does anyone have answer to the question?..... thx for any input

He's talking about the Rig you'll be putting on the trailer+the weight of the trailer frame = possibly more than the max. capacity of the axles.

As far as reinforcement, If you'r going to go to the trouble of plating over the existing frame, Why not just box it? You would have to notch for the x-members, but if you weld all of it to gether you would have a really strong frame.

ok well from reading... im finding trailer home axles are atleast 5200#'s so i think ill be good there

And when you say boxing the frame.. basically I am boxing the outside of the exsisting frame with 4x2 .180 wall rectangle tube...

are you saying just box the channel with flat bar?..... that would be fairly cheap i guess... hmmm...

no one can answer that?...

Yes... just box the channel with flat bar. It will be cheap and simple. Are you sure those axles can handle the weight?

hmm.... i might do that.. if you think itll be strong enough.

and did you read any of the other posts?... i looked up about MHA's... and it seems the lighter of the two styles are 5200#'s so...... i think 11400#s for axles will be plenty.

2 x 5200 = 11,400???

New math??? :confused: :flipoff2:

lol.... yea you didnt get the memo...

[Copenhagen]

fuck it.. hah guess no one can answer my question.. Im pretty sure itllbe alright... just wanted a confidence booster..

It doesn't seem as though you even know exactly what axles you have under there:rolleyes: .


And I've dealt with many trailers built for sand rails and they usually don't have the ability to carry 10,400lbs:)

have you not seen that i said they are mobile home axles?..

from what ive read by searching. there were two kinds of mobile home axles used... the lighter of the two is rated for 5200 pounds.. im not going to look up what the heavier of the two is rated... but the main difference was wall thickness on the axle tubes...

Whoever said i was going to be hauling 10,400 pounds... I said that, If what i read about mobile axles is true.. then my axles can stand UP TO 10400 pounds... my blazer weighs in right around 5500...

LOL I wasnt asking about my axles anyway... i was asking about my FRAME...

NO big deal.. I had my buddy who used to build trailers come look at it, and he thinks itll be good to go... so lets just let this thread drown into the depths...
