Bob,
I have seen those before, they work pretty well. What are the economics of
finding a 220volt 4-5 hp motor and using it to power the device. I think
they're quite a bit (lots) less expensive than the converter. Even if you
had to alter a mounting plate it would be worth it. Typically a 5-6 HP
compresser would have just the item I believe. Getting it to work and mate
with the gear reduction shouldn't be too difficult.
There are actually some places that specialize in "used" electrical
equipment. Even a new motor is likely just a couple of hundred dollars from
a place like Grainger. There are better deals than theirs out there.......
Not a bad price.

Russ,
It's a Werther assymetrical 2 post screw type lift, actually 2 of them.
Electrical/Mechanical. They are screw driven off one 4 HP 3 phase motor. The
motor sits on top of one post and runs that screw. A driveshaft arrangement
though a raised floor panel runs the other side. The Phase converter
manufacturers say it will take a 7.5 HP rotory converter ($600) to run it,
but Werther says other people have tried it and it doesn't work. I can't see
why it wouldn't work, but I don't want to go out and throuw good money after
bad. The lifts were cheap ($850), so the total price is very attractive
compared to a new lift of the same capacity and features.
