Good afternoon,
I have to change the position pot in my PST-71 rotator for my Rohn 55
rotating tower, I guess the 10 degree temp last night finally got to it.
It has been going bad for a few weeks.
The rotator is five feet above ground, but it weighs over 50 pounds. I
used to handle it with a pulley mounted on a 3 inch angle bracket which I
temporarily bolt to the side of the tower a few feet above the rotator.
The trouble is, at age 77 I no longer have the arm strength that I once
had. So, I would like to use a multi-sheave system to reduce the force
necessary to lift it off and reinstall it. I have a two pully system which
would reduce it to half, but I think I had better go with a three or four
section system.
All this to ask what is a good three or four sheave fully? It only need be
a two inch diameter. Or, a one inch would work also. If you have any
knowledge which one and where to get it, it would be appreciated. In the
meantime, I will do my own searching. But, I thought it would be good to
have the input of someone who has actually used what they recommend.
As always, I look forward to the excellent advice that comes from this
group.
73,
Dave, K4TO
