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,
