[TowerTalk] Pre-Lube ?

FWIW, they claim it is used by the US Navy for the arrestor cables on our
aircraft carriers.  That's what sold me!

Yes, but I think the ingredients are proprietary - check the MSDS.

Wire rope strands rub against each other when traversing sheaves so
lubrication is important.  Also corrosion protection for longevity. 
Pre-Lube has a high carrier solvent content and wicks quickly into the
cable, and leaves minimal residue on the outside to collect dirt, bugs etc.

In other applications, the cable lubes I have used basically leave a lot of
grease on the surface, not good.

My trick for getting the spray on the cable is to slit a cheap plastic
funnel so it can wrap around the cable.  Then the spray is contained and
runs down the cable 3 feet or so.  I do this from a boom lift with the tower
retracted (HDX589), all of the cables at each level then drop down the 3
feet and repeat.  If doing this climbing probably starting at the bottom and
moving up makes more sense.  Obviously, don't climb an extended tower and
block one that is retracted.

It takes about 2 cans per 589.  There are a lot of 589 cables so having a
routine is important to not have holidays.  Some cable never leaves the
drums so they get a soaking spray.
