I picked up a gantry last week. I bought a HF Gantry from a guy on Craigslist. All the components look brand new and unused. I was missing the top beam. I paid 250 for it and 160 for an I Beam from my steel guy along with the two end plates which I'll have to drill and weld to the beam. It'll be a piece of cake to build and I'm in for 410. I already have a trolley and a chain fall so I'm set. I'm gona pick up a cheap crane scale so while assembling I can get a weight on the cab, bed, frame and motor........just to satisfy my OCD LOL
