Welding Rig Trailer Concept Drawing

admin

This is my concept for my 5'x8' trailer based welding rig.  Thinking of putting a 4x6x1/4" table on the side.  I will frame it with 2x2x1/8" square tube and use 2 square tube jacks as the legs.  The interior will be braced with 2x2x1/8" angle.  The table will be raised and lowered with a small worm drive manual winch and cables.What do you think about the rig concept and the size/thickness of the table?  Any ideas and suggestions will be appreciated.  I have looked at many of the posts and seen some really nice rigs!!

Reply:Hmm...can't say I understand your drawing, but good luck!  Post pics throughout it's development.
Reply:Looks good.  How will you get your welder in and out. ...Over the top of the rack?  Or do you have a way to slide it in from the back.I like the drawing, be interested in seeing it fabricated.
Reply:very cool idea. from the drawing it seems pretty interesting. i would also like to see it built. "Ask not for whom the bone bones, it bones for thee" - Bender
Reply:The welder will come out using long forks on a front end loader.  Lift it 3", and back it out.  I have also considered bolting the top cross braces above the welder in place to allow it to be lifted from above.  How would you suggest mounting the tanks.  I am considering building bands, but have also considered chain and bolts to bind it.Good feed back.  Still looking for comments on the table idea......  Off to beat the heat this AM and finish the roll bar.  Expecting 96+ with 80%+ humidity again today.Rob PageMiller Bobcat 250Lincoln SP170-T
Reply:Just my opinion, but I don't really see the need for the diagonal in your frame. (if I am understanding it correctly)  I think your trailer would be stronger using cross members the full width with of the frame.  The floor, especially if sheet steel and welded in place, will stop any twisting of the frame.  Here is a couple pics of the last trailer I built and used.  My helper uses it now since I have gone to a truck mounted equipment.  I always have used a chain with bolt welded to the end to tighten tanks in the cradle.  No budging one once its tightened.  Definitely my favorite method.I'm a Lover, Fighter, Wild horse Rider, and a pretty good welding man......
Reply:Now I see the confusion!!      The drawing in the top left is the framing under the fold down work table.  After reading a lot over the last few days, I'll probably change the interior angle bracing to flat "on Edge" bracing.I hope this clears up the drawing a little bit.  I will post pictures of the trailer as it sits tomorrow.  I already have the Bobcat mounted on it.  Bolted through the wood and into the frame.  Nuts tack welded on.  Saw a post or two using a "trailer receiver" concept for mounting the vise and other things to the table.  I am going to incorporate that concept to mount the vise and have some light bending jigs.    The overhead frame will also provide support for a shade/rain cover and I will be able to deploy a side cover over the table also.  Shade good!!!!!How are you powering your lights on your trailers?  Running griders, etc., is easy enough since I would not be stick welding at the same time.  If I had to stick weld and needed lights, the only solution I see is a small genset for lights/compressor etc..Rob PageMiller Bobcat 250Lincoln SP170-T

Reply:Here is the starting point.   I will be starting a new thread in "Projects" with my ideas, your ideas, and the progress.Thanks for everyone's help.  Wish me luck.    Rob PageMiller Bobcat 250Lincoln SP170-T
