Hi Chuck,
Im not the best resource to answer this question but I do own both a
crankup and a fixed freestanding tower. To be honest I dont think a
crankup is your best choice for the load you are wanting to support.
You shouldnt guy a crankup tower ever. Plus I think you have too much
height above the top of the tower as well.
Ive seen a lot of wind generators on rohn ssv type of freestanding
towers or rohn 45-55 of guyed structures. I think you would want
something of this size to start with. You also need to find out about
how much windload you will be supporting as well. That will dictate all
the appropriate infastructure below.
btw, I was considering putting up a wind generator at my place so I put
up a ham tower that may eventually support it if I get bored with ham
radio. Its an 80ft rohn ssv tower thats in 23 yards of concrete.
Goodluck, its a very cool project. You are smart to ask and be safe.

Subject: [TowerTalk] Tri-Ex HS 588
I am building a wind generator and have bought a Tri-Ex HS 588
tower from a
neighbor. This was evidently a three section 58' crank-up tower but the
top
section was missing.
I want to weld in some support plates in the top and install a 12'
piece of
schedule 40 pipe to set my generator on. the generator will weigh about
250 lbs
with blades.
The local building inspector tells me I will have to have an
engineering
report saying the tower can be used for the purpose. I plan to guy the
tower at
20' and again at about 40' but have no idea how guying a self
supporting tower
affects it's wind load capacity.
Does anyone have any specs on this tower? Anyone have any
suggestions on how
to deal with this problem? I have looked into new towers but quickly
found out
that I would have more money in the tower than I could ever get out of
Renewable
Energy.
Thanks for your thoughts and time, CHUCK
