welded trailer repair

Post by welderbob » Sun Oct 13, 2013 7:15 am

Sorry I'm way behind on posting projects. We had a 38' aluminum trailer come to the shop for repair. It appear that years of hard backing turns had cracked the area the cross frame and axle mounting area. The trailer was built by MYCO trailers in Jettyland (Florida). I made a quick phone call to Myco to confirm the way that We had proposed to repair the trailer. The were very nice and suggested a small gusset between the cross frame and main frame to prevent flexing.

I apologize if the pictures are out of order. :
First we drilled the crack at the ends
We gouged out the crack
Welded the crack
Added a doubler plate to the outside
Welded a a small gusset to the cross frame.

Looks like the Cross Member should have been closer the Axle if not directly over it.

Oh, NICE looking welds by the way. :smitty:

Yep, I believe they are just a bit "prouder" of them trailers than my Rollsaxle, and RollsAxle is "proud" for sure. They always seem to be under serious penis extender boats around here.

Yer, Big Fountains, Yellowfins and other assorted "hey look at me now" type boats.

:shocked: :shocked: Please excuse me for what I'm about to do... :shocked: :shocked:

I was a little surprised that the axles was just bolted to the edge of the channel. There was nothing extra in the axle area. I guess they have it figured out. The trailer is 10 years old. I believe that the trailer was rated for 18,000 lbs.
