The seller, Shop Equipment USA of Hayward, CA, works with an independent delivery company that charged me $400 to pick it up in Hayward and to tow it about 200 miles to my location. The young man who delivered it did about 90+% of the work of unloading it onto the ground (I had to help him a little bit). Then I broke the package down and carried the heavy parts into my garage separately with my tractor, using the lift boom from my post hole auger on the 3-point hitch.
In retrospect, I would have first obtained a large, tapered pin in order to line up the bolt holes in the end of the ramps with their mating holes in the yokes. Lining up those holes and starting the bolts was the only difficulty that I had in assembling it.
The written instructions aren't really that great for somebody who has never assembled a lift before, but there are videos on the internet about how to assemble it.
