[TowerTalk] Torque Limiter

The recent thread concerning a rusted nut on a torque limiter caught me
completely off guard. I have run a 200 foot rotating Rohn 55 with a
Rotating Tower Systems chain drive without a torque limiting device for 28
years without a problem. I had lots of big antennas, heavy, and not
particularly well balanced weight-wise or aerodynamically.
I have never had to rebuild a rotator or had any damage to chains or
So my question is:
Do you need one for an adequately designed drive system? I'm not trying to
raise controversy or start a debate. I am genuinely surprised to learn
that there are such things.
I do know that some folks put large springs on some mast installations that
use smaller rotators. I have just never heard of a torque limiter on a
rotating tower. I guess I am naive and a bit lucky to have survived for 28
years without one. I suppose now that I know about it, it will break. :-)
So what is everyone using in this department?
