Hi,
I have a Rohn 45 foldover I was hoping to erect this saturday - I have
a bunch of people coming over to help. Unfortunately, as I walked
through the pieces today, I found a large problem - the fold over
assembly does not match the engineering diagram I have! My diagram is
from 1981.
I must have an older model.
The arm terminates in a bracket which has two holes:
------------------------------------

----------------------------| |
| |
| O |

| O |
|____|
presumably one is for a bolt/thimble to attach to the winch and one is
to attach, somehow, to the tower leg. But the exact details are unclear
to me.
The diagram I have shows these two functions at different points on the
fold over assembly - I don't have a corresponding point for the winch
cable to attach.
I really really really need a copy of the engineering information for
this tower ASAP that explains my arm - if I can't find it, I'm afraid
it isn't going up saturday. My fault for waiting to discover this.
The other big question is whether I should assemble this tower with:
27' below the hinge and 36' above (which is about what Rohn suggests) or
37' below the hinge and 27' above (which sounds safer to me - but i
have a guy here vigorously arguing I need to follow Rohn's model)
I am guying this at the hinge and at the top.
Thanks for any advice/suggestions.
