[TowerTalk] Rohn 45 Bent Leg

[K7LXC at aol.com]

>  I need some advice.  I have a 70' Rohn 45 and had a  guy with a tractor 
back into and damage one of the legs.  As well, the leg  was 
hit hard enough to bend the diagonal cross support.  I could  probably, 
with assistance of a come along, bend the leg back into place 
and  bend the diagonal support back into place as well, but that would not 
resolve  the huge indentation which resulted from the 
contact with the tractor.,  e.g., the leg's strength would still be 
compromised.  There is no antenna  on top of the tower; I was just 
getting ready to place my TH-11.  The  tower is guyed at 30' and 50' at the 
current  time.

I'll put in my 2 cents worth. R45G will  take a lot of abuse so I'd put 
this in the 'not fatal' category. I'd use your  comealong and bend it back into 
place and then splint it with some angle iron  and U-bolts. Seventy feet of 
45G is a pretty  modest installation whereas  45G is rated up to 300 feet 
so you won't be pushing the envelope even with  a small defect in the leg. 
 
    You're over-engineering the installation by using 3  sets of guys for 
70' so I can appreciate your concern. If it was my tower, I'd  do the above 
repair.
 
Cheers,
