I plan to mount it on the ceiling at the top of the stairs. Put the pinball on a two wheel dolly, connect the hook to the handle end. Press the button and let the hoist do all the work while I guide the pin. At the top of my staircase it is quite narrow and hard to maneuver, but with the hoist I could lift the pin right off the ground and spin it in mid-air then set it back down. After that I just wheel it into the garage.
The most difficult part for me is getting the pin up and down the stairs. The rest is pretty easy. I am going to make a fold-able wooden ramp with wooden guiderails to lock the dolly wheels in position and keep the pin centered as the hoist pulls the pin up the stairs.
My 'grand design' is to make this work similar to a drive-in car wash.
