Could a couple of you take a look at the Grainger
model # 5K539 gearmotor and see if this would be a
suitable gearmotor for my application (driving the
winch on my tower) ?? i just discovered that i have
access to an older version of this from Dayton Motor
it appears to be a little heaftier and the ratings are
similar with slightly more torque (719).

thanks

Dan,
Unless the it is a wormgear arrangement I would not use it for a cable winch 
drive.  That assumes the cable drum is free wheeling.  If you are driving a 
"boat" winch with built in braking it should be no problem.  I would design the 
cable/winch mechanism to also provide positive pull-down which a "boat" winch 
can not provide.
