Findlay was (and may still be) the home of the Self-Lifting Piano Truck
Company.  They make various kinds of lifting machines for moving pianos
about.  I have the one for full-sized uprights that consists of a pair
of felt-covered trucks that strap to either end of the piano.  Each
truck has a set of handles at just the right height, and a bail that
raises the piano about an inch onto a long steel roller at the base of
the truck.  With this I can move my piano on the level alone, and up
into my horse trailer with the help of one other person.  Strength is
helpful but not absolutely necessary if one is content to work slowly.
(Indeed, too much strength combined with insufficient knowledge and a
desire for haste will flip an upright on its back quickly.  As we in MMD
know, but our friends may not, they are top heavy.)

My trucks also have casters on the "side" faces, and a ratchet on the
roller, enabling the strong and brave to upend a piano for wheeling
through tight spots.  I have attempted this feat only rarely, and always
with muscular help.

At the time I bought my piano truck from them, maybe ten years ago, the
company consisted of one old man, who had inherited the company from his
father or grandfather.  As far as I can tell, the model I own is
identical to what they were building back in 1901.
