IIRC, my US Tower TX-472 + Force12 C-4XL goes up/down in
a little over 30 seconds, using a Milwaukee Super Hawg (pn
1680-20) that runs at 450rpm. It pulls 13A at full load and
should not be confused with the smaller Hole Hawg. The
tower uses Fulton K-2550 winches.
The only issue with taking my tower up/down in 30 seconds is,
I have several feedlines hanging off the tower, along with two
wire antennas. I HAVE TO stop periodically in order to keep
things from tangling. So far, it runs stone cold.
I found the Super Hawg as a factory refurbished unit on eBay
for a little over $200 shipped.

There are rating and there are ratings. Most drill motors
are rated for
intermittent duty with short run times and long cooling
cycles.
I purchased the largest Dewalt that Lowe's carries.
Drilling 3/4" holes
in 1/2" thick I-beam, I burned it up in less than 5 minutes
and I had
just purchased it.
Drill motors for mixing as have been listed on here may be
rated
differently, or with a larger reserve/safety factor than
those for
drilling holes. IOW two motors rated at 13A with one
for mixing and one
for drilling may not have the same ability to raise a
tower.
I've not found a correlation in the ratings. From
experience, I've
found a drastic difference in ratings for drill motors rated
for long
run times VS the typical short run times for drilling
holes.
I'd limit my purchases to a motor rated for long run times
such as mixing.
