Here's my suggestion use the crane if have to connect it to the tower if
the crane has two cables use one connected to the tower and one to
basket that lifts personnel up to lift you up to where you the crane has
to attach go up in the basket to connect the crane cable to the tower
this I believe is safer the climbing it because your in the cage basket
supported by the crane also keep in mind you can buy Rohn 25g 10ft
sections for about $75 each at R&L electronics I just checked last month
will the cost of take down be worth the price of new tower or cheaper in
the long run. The crane would have to be free to use to be worth it or
just the price of fuel for crane.
$750 versus 1500-2500 for crane not worth the cost.

Subject: [TowerTalk] Take down Rohn 25G tower with crane?
Hello All,
I have been asked to help take down a tower for a friend, Scott, AG4GO.
It
is 10 sections of Rohn 25G in commercial use that was given to my friend
for
free. The top section is a sleeve-top, and there is a single,
folded-monopole commercial antenna on top.
After inspecting the tower, I determined that it definitely was not
properly
installed. It is only guyed at 2 heights, 50 and 90 feet, and the
anchors
are 12 foot, 4" diameter steel pipes that make inspecting the guying
hardware difficult, since they are so high. There are only 2 cable
clamps at
each termination, and some of them are saddled on the wrong side,
pinching
the 'live', load-bearing side of the cable.
Some of the hardware has a little rust, and the top guys are loose with
considerable sag.
All of the tower joint bolts are rusted and some of the joints we could
see
at the bottom had been overtightened such that the legs were somewhat
squeezed out-of-round. However, the sections themselves seem to be
structurally sound.
This tower has been up for well over 10 years. The guy hardware is
substandard, but not broken. I think I could climb the tower safely if I
placed temporary guys on it, but I am hesitant to do this.
Scott can arrange for a crane to help us, very inexpensively. My
question
is, can this tower be picked up and layed down in one piece without
bending
it? This would be much safer, and would allow many people to work on the
tower joint bolts simultaneously, saving us a lot of time.
If any of you have done this with Rohn 25 of similar height, please
write
and describe how you did it.
Any other comments and recommendations are welcome.
Thanks,
