Beware the dead weight limitation of the Rohn Foldover towers: There are two
versions; the most recent version is specified to handle a maximum of 135
pounds dead weight AT THE APEX. with a long mast that number needs to be
derated
to the equivalent number of foot pounds
I don't have any data for the older version but my recollection is maybe 100
pounds dead weight, again, at the apex.
I have seen these towers fail on several occasions by exceeded the safe
weight at the top. This is a case of it WILL FAIL, not that it might fail if
the
rating is exceeded.
Not trying to scare you here, but I am trying to get your attention to this
important issue.

I have a Rohn 45 TiltOver.
The arm needs to be straightened and reinforced.
I need to know about the cable, pulley, crank pieces.
Anyone rebuilt one of these using readily available
components who could share the specs, please?
If it impacts component choices, as I anticipate that
it does, I will only be tilting about 55 feet of tower
plus a 20 foot mast (15 feet out the top) with a Force 12
C3SS and a couple of other smaller beams or a beam and a
VHF/UHF vertical.
I would like to start locating and acquiring what I need
a little at a time (as the budget allows).
