> I am missing something here as US Tower advises against lubricating
cables.
The LXC Prime Directive still applies - to "DO what the manufacturer
says". In this case, UST is NOT the manufacturer of the wire rope. Actual
wire rope manufacturers do indeed recommend lubricating the cables. In this
case the tower manufacturer is wrong. Remember that tower companies are
insurance driven enterprises and they are reluctant to give you much in the
way
of info due to liability risk exposure. In this case IMO their advice is
more designed to keep you from climbing around on their tower than actual PM
advice.
> What are you gaining by lubricating cable?
The strands rub against each other when the cable is moving. That's
why you want to LUBRICATE them. Many crank-ups groan and make noise as
they're raised. After lubricating them, everything is very quiet. Commercial
applications are used hundreds if not thousands of times more than your
typical ham crank-up so neglecting to lube the crank-up cables isn't a fatal
problem.
> I my opinion if a un-lubricated galvanized cable shows signs of rust,
it is time to replace it.
See other recent post related to cable replacement.
