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.
