Basically, Stan's approach is to TAKE DOWN the tower and reinstall it. Here are two alternative approaches: N4AR discovered his 200 ft R45 tower with a 4 high stack of 4L20's had rotated at the base
Yes, but for how much longer? Just because it can be done doesn't mean it's safe or permanent by any means. If the tower fell, causing measurable property insurance, would the insurance company be ob
So, uh, who would climb such a tower to install the tribanders? Bill Coleman, AA4LR, PP-ASEL Mail: aa4lr@arrl.net Quote: "Not within a thousand years will man ever fly!" -- Wilbur Wright, 1901
I like Tom's suggestions for THOSE towers. The base problems with those towers was either rust or shearing. The tower in question had standing water in the leg and it froze, splitting the leg. The on
And what do you see as the problem? The Legs are NOT rusted above the break at ground level, The Legs are braced so they cannot move out or in, The space between ground and the next steps is filled w
Lifting a guyed tower "a few inches" is MUCH more difficult than it sounds. W1EVT told me he did this to one of his 140 ft R25 towers (supporting only WIRE antennas) and they had to loosen the guys t
My old 80 ft tower had this problem, cracks in all three legs from water freezing, splitting the legs. The cracks were about a foot up from the bottom of the tower. I welded a "dot" at the upper and
Since I sent this to you personally Tom, and you have answered on the list, I'll answer on the list. The rusting ground level is of grave concern. Are they? It is hard to tell from the description. W
This is dependent on the part of the USA you live in. Those of us that have live in the Dakotas and northern regions of the US and have done Commercial tower install's know this can be very dangerous
Obviously we are in disagreement over the magnitude of the HORIZONTAL Forces at the Base of a Guyed Tower. Please explain the origin of the horizontal forces you are concerned about acting on the bas
I am chemical engineer so don't bash me too much but the way I understand it, there are horizontal forces acting on a tower's base, albeit less than the vertical forces. Imagine the tower being blown
SNIP No PE. The pieces of angle iron are painted and much thicker than a tower leg. N4KG What lateral loads? The tower is guyed at 20, 40, 60, 75 ft. with torgue arms at 40 and 75 ft. Are you saying
Just pour concret over the whole length of tower then who cares if it rusts. I am sure someone will point out the error of my humor, like the amount, size, bends and type of rebar that would be neede
N4KG response inserted below. This is valid for a tower with only ONE set of guys where the guys act as a pivot point. The force at the base will be reduced by the ratio of the spacing between the gu
Tom: If you can PROVE that all the guys are tensioned correctly, then you can PROVE that there is no lateral force present. I suggest that you can offer no proof. John KC4ZXX -- Original Message -- s
Greetings Towertalkians I just returned from a good friend of mine's place where we did some tower work. Upon a close inspection of his tower, we found a 2 1/2" split on the inside of one of his Rohn
Chuck: I am taking off my S.E.,P.E. hat here and giving you a potential fix. Get a piece of 1"x1"x1/8" steel angle about 12" long. Place it at the split location as best you can trying to center it o
If the tower and problem was mine, I would: Rust proof the crack (cold galvanizing spray) to prevent any future corrosion. 1. Put bunch of hose clamps close to each other over the length of crack. Th
not sure how high the crack/split is above ground. But if the cause of the water accumalation is due to the legs being clogged in the base, you may consider checking that leg below the crack as well.
