There should always be some equally distributed tension. On any "large" towers I've seen erected, there was a survey spotter involved, along with a "hugemongus" meter at each termination point.
Usually the engineer or manufacturer designates the guy tension and size on the prints. Are there prints on site or available?

If you notice more slack on one side or leg than another, that should sound an alarm bell in your mind. How many guys terminate at each point on the ground?

You can move the guys with your hand, and if you give the tower a thump with your hand, it wiggles slightly. I'm not telling this for the original poster to use it as a guide for them, (I'm no expert)I guess I'm just looking for reassurance for our tower? It's been up for over a year now and has sustained winds up to 70Mph on many occasions.

also, on hot days the wire will be loose, while on cold days it will be tight. the trick to tensioning the wire is not to tighten it so much that it causes a failure during extreme cold.

this is NOT a job for the inexperienced. all sides have to be equal.

Lack of Preparation on YOUR Part does NOT Constitute an Emergency on Mine!]]> http://www.dslreports.com/forum/remark,14854860 Mon, 21 Nov 2005 18:02:28 EDT Re: Tower guy wires http://www.dslreports.com/forum/remark,14854722 slipstream1 : The guy wires will have a spec for the tension they should have in relation to the tower. The proper way to tension the guy wires would be with a dyno and a transit. You will want to make sure the tower is plumb as well as tensioned. Most newer wires will have a color code on the preform that will tell you what the size is and what the tension should be. You should also be able to do a rebound test on the wires to determine the tension of the wires. look on the internet and find out the time it takes a wire to rebound from a hard hit on it with your hand. You hit the wire and time the rebound. That time correlates with the size of wire and will ball park the tension for you. Then you can tell if it is close or loose.]]> http://www.dslreports.com/forum/remark,14854722 Mon, 21 Nov 2005 17:45:07 EDT Re: Tower guy wires http://www.dslreports.com/forum/remark,14850244 John Galt :

What does a tower pro charge to inspect it?
About $95-$125 an hour...plus travel time. They probably have a minimum.

Call the local land mobile radio shop...they might be able to help you at a cheaper rate. They should be able to identify any problems.

Then, having done this initial evaluation, if you need "real work" done, then get the "Big Guys".

All towers have spec's on guy wire tension.
Rohn 25G is about 400 pounds of pull. You will need a Dyno to do it right. We have installed our own towers. We rent the crane and get a Dyno from a friend that pulls guy wires on his day job. The Dyno is tested monthly. A guy tower will move a small amount not much. Even when we finish with our towers. You can see a little sag in the wire.

The main thing is find out the brand and type of the tower to get the spec's.]]> http://www.dslreports.com/forum/remark,14850210 Mon, 21 Nov 2005 00:39:01 EDT Re: Tower guy wires http://www.dslreports.com/forum/remark,14849656 superdog :

The guys look loose to me, but maybe they are supposed to be that way.
They are supposed to be a "little" loose. It would cause structural failure if all of the guys were stretched tight. It is designed to have some "give" in it to allow the pressure exerted on it to be applied slowly and not instantly.

Any hints?
How tall is it?. Depending on the tower height and other variables, those guys probably shouldn't be tight. I would CAUTION You against climbing anything You are not 100% certain is in perfect working order. You are in OK, so when is the last time a twister of Oz proportion "tested" this thing?

The tower is quite old, and needs paint for sure. I looked at it, from ground level of course, and it appears structurally good. I see no rust or any cracks, bulges, or anything like that. The guys do appear to be looser than they should. My question is how tight should they be? What is the best way to tighten them? One side looks like the turnbuckles wouldn't tighten them enough, but I could be wrong. The other two sides, I think the turnbucles would do the job. Any hints?
