Plans for a small tug/tow device for C172?

Anyone seen any plans for an electric tug for a 172? I can get my
hands on a motor, but not sure how much horsepower it should have, or
really have a plan of attack for putting something together.

Yes, our 172 does need a tug. We just got a new hangar, and you have
to push it up a bit of an incline, and at the same time go over a 3/4"
lip to enter the hangar. Nearly impossible for one pilot to do alone.
We tried pulling the plane in with a block & tackle, but we were
afraid we'd rip the tail tiedown off after one try.

Thanks
DK
