Steve is right. US Tower makes a deluxe unit. Raising and lowering the
tower on a daily basis calls for a top notch motor drive. The alternatives
are slim beyond roll your own. There was a system from Towtec 15 + years
ago that replaced the winch and used a small motor but it took 30 minutes
each way for the 55 footer and 45 minutes for the 71'. Towtec was bought
by Glenn Martin as I remember. You might find someone with a danaged tower
that has the winch/motor intact as the last ditch alternative.
