I wonder why crane companies keep their cables (on million dollar
cranes) lubed religiously?
On this particular topic, I would not place much faith in the
manufacturer's edicts, unless you're looking for a reason to keep busy
replacing the cables more often than otherwise needed.

Over the years on this list there has been a persistent thread
suggesting it is essential to lubricate your crank-up tower cables.
See the link below for a .pdf FAQ document from US tower wherein it
is stated twice NOT to lubricate the cables. Below I also
cut-and-pasted the relevant Q & A's. There may be those who will
argue that lube is a must, but I would suggest following the advice
of those who build the towers.....even if they don't build the
cable.
As a US tower owner for 14 years, I have NEVER put lube on my cables
and they have remained in excellent condition. They have been
replaced twice, but NOT because of any noticeable wear, but only as a
precaution as per the manufacturers advice.

QUESTION : Cable replacement and maintenance.
ANSWER : We recommend that you replace your cables every three years,
with regular inspection of
the cables. You need to look for any rust, broken strains and/or
kinking. We do not recommend
lubricating the cables as can cause a more serious damage to them.
QUESTION : Can the cables be lubricated?
ANSWER : We do not recommend lubricating the cables. The lubrication
only attracts dirt and debris
causing cuts and scarring into the cable resulting in a shortened
cable life span. _______________________________________________
