I motorized my Hazer with a 110 volt electric winch from Harbor Freight.
They have several to choose from with the capacity and that run on 110
volts.

Subject: Re: [TowerTalk] Motorize a "Hazer"
I have a 60 foot Rohn 25 with a Trolley Hazer on it ...been in use as a
test/build-it tower for over 10 years.... It's nice to build antennas at
waist level, then crank'em up and test etc...you get the picture...
But now the arms and knees are saying no more hand cranking so why not
motorize it....???
Right now its got a 1500 pound 5:1 Fulton on it and no problems, it pulls a
5/16 cable up 60 feet and down 55 feet with 8 turns still on the drum...
I figure the greatest weight including Hazer/rotor/antenna would be less
than 150 pounds, so at this point the 1500 pound Fulton hasn't grunted
yet...
Now the Hazer folks sell a 12 volt winch for a 48 foot tower and its got a
1500 pound 12v horizontal winch and nobody wants to talk about a vertical
pull figures...
Superwinch has a new 8400 pound horizontal pull that will handle the 120
feet of cable and is positive up and down with brake etc...and its only
$400.00 The gear ratio is 235:1 .... if this is a workable item I would put
a programmable ampmeter in the DC line and set alarm points in it so if
something
gets stuck and the amperage goes up/spikes, the alarm will sound etc....
The only thing I don't like is the 12 volts.....I would have to run it off
the truck in order to get the DC amperage necessary ....
Or maybe the way to go would be to buy a 4500 pound Fulton put a pulley on
and 50:1 gear reduction ... a 1HP motor wire for up/down and be done with
it..???
Of course the costs going this route would be around 6-700 dollars...
Here are the specs on the Superwinch:
