I purchased one of these last week and fabricated a mount that I bolted to one of the upright hanger beams.
www.harborfreight.com/automotive-motorc ... 96127.html I paid $110.00 for it after finding a 20% off coupon in one of my hunting magazines. I was going to get what others have suggested with a 12 volt powered winch and a battery but I figured by the time I bought the $50 winch and then another $50 for a battery it was the same cost roughly.
I had to replace the cable with a longer one due to my hangar having an incline at the door. Had the plane nearly full of fuel (guessing close to 1100lbs.)
and the winch worked fine. It is slow but then I don't hurt my back trying to wrestle the plane in the hangar anymore either.

Before I installed the winch I used my Argo 8-wheeler but in the winter when I had tracks on it it wouldn't do the job as the tracks just spun on the frozen concrete floor.
