   I do actually have a gantry crane.  Sorta.  Its an twin a-frame with a   
   cross bar made out of what looks like old heavy well casing all welded   
   up.  Its high enough to lift an engine out of the engine bay of a pickup   
   truck, and just barely wide enough to fit around the fenders of one.   
   Not much use for this application though.  A fellow I know (not a good   
   human being) loaned it to my dad maybe 50 years ago.  My dad told him he   
   could have it back when the guy paid him the money he owed him.  I don't   
   think my dad ever got his money back because we still have it, and   
   amazingly that coyote never stole it out from behind the grocery store   
   where we kept it in an open yard most of those years.  Of course all I   
   ever used it for was pulling and installing engines.  Mostly (now that I   
   think about exclusively) V8s.  318, 360, 351, etc etc... No wheels.   
   Just steel pads under the four feet.  I kinda liked it better than a   
   cherry picker for pulling an engine.  I guess next time I run out to my   
   folks place I'll have to see if I can drag it up onto a trailer.  (Its   
   freaking heavy.)  I might need a gantry crane just to stand this one   
   back up.   
      
   You know... there is another cherry picker out there too...  and another   
   engine stand...

   The Net has several plans to build your own, which might help with the   
   engineering of swapping a long and strong enough beam for the well casing   
   and choosing suitable casters. Trailer tongue jacks could move it (unloaded)   
   and set it down for use.

   My gantry hoist is meant to be set up by hand in the woods to lift and move   
   a log or boulder, and disassemble for compact storage. Though it works very   
   well on the sawmill it has too many compromises to be a good pattern for   
   general use indoors.
