A few years back, an A-Frame device was pictured on a website that was built to lift the body of a car from its frame. I have used several different methods in the past 4 decades to do this to include several guys and a case of beer. Many here use engine hoists, overhead cranes, Camper Lifts, forklifts or a combination of all of them. I decided that I needed to build my own device based upon what I could remember - did a design and asked a fellow member to review it for soundness. Based upon his thoughts, I ordered up some tubing and began following my drawings. Today, I managed to get the first of the two units complete. I made it from square tube and as one friend was quoted to say, "Looks like it could support a locomotive". The units may be a bit of overkill, my norm but I think it can be used for other lifting/extraction tasks. I had already built some lifting bars specific to the trifives and can be seen in the picture below.
My main three criteria were multifunctional, able to lift a complete body (Glass, Doors and Interior) and portable. The unit pictured will go down to five easy to move parts with just a few bolts.
