[TowerTalk] Fwd: Guyed + self supporting /2 ??

[Hans Hammarquist via TowerTalk]

If you look carefully at the picture you'll see that each bracket has a U-bolt grabbing the Z rod, thereby spreading the load to all three legs.


I used (a home made) plate with three holes, one for each leg to connect the guy wires to my tower.


The tower was built of parts from a self-supporting tower. By guying it I increased the maximum wind-load from 85 to 135 mph. One note; the guy wires do not attach to the top of the tower but a few sections down. By that the bending from wind-load is "evened out" between the sections. I built;t the base very stiff so the bending of the tower takes the form of a compete sinusiod and the bending of the top will help the section just under that guy wire to "straighten out".

This is not always correct.  My Rohn 65G guy brackets 
http://www.dxengineering.com/parts/roh-ga65gd only attach to one leg.

Guys should NOT attach directly to the tower legs! This weakens the tower,
by applying a lateral force to only one leg. ROHN has a guy attachment
saddle that fits AROUND the tower. The saddle absorbs lateral forces,
while vertical forces are transferred to the tower. Look at the ROHN site
for proper guy attachment.
