need help with iron flex

Dutchman · Jun 14, 2014

I have some flex on my tandem axle trailer ..where the axles are mounted on
was thinking I heard if you use a pc of angle iron with the edges down on the flat and the point out it will help ...
Can anyone tell me if this is true ???

Some pictures would help, along with what you're hauling, how it's loaded, what it weighs...

Sounds like the frame is insufficient to handle the weight. Yes, you can reinforce it with angle, but not with the angle on it's side. The best way would involve removing the fenders and the spring mounting hardware, then welding angle with the flange up, to the bottom of the frame, and reattaching the spring hardware to the bottom of the angle. The angle would need to be as wide as the bottom of the existing frame. The longer, the better.

But... A couple of things to consider.

One, by welding the angle over the existing frame, it will create a water trap between the frame and angle, something to consider if you live in a salt use area.

Two, will this solve the problem or just move it to the next weakest link? How's the rest of the trailer? What about the axles, wheels, tires? Would you be better off using the time and money upgrading to a larger trailer?

If you reinforce a frame by adding material it is possible to reduce the deflection (flex) for a given load. Deflection follows a property called the "second moment of cross sectional area..." and is typically designated by the letter "I" in reference material. When material is added, generally it is desired to add the material in a manner to give the greatest increase in "I".

If you care to provide details (shape, dimensions and thickness) of your trailer frame I could probably make a suggestion.
