K7LXC breaks the prime directive for lubricating crank-up cables. He sells
Prelube 6 on his site and recommends using it. And yes, any professional user
of wire rope always lubricates their cables on a regular maintenance/inspection
schedule.
It baffles me why anyone would not lube the cable with the *proper* lubricant
since the cable is THE critical link in a crank-up.
It's a testament to how well the cable holds up that more failures haven't
occurred. That and it's way over-sized to the load.

Lubricating the cable does go against the K7LXC prime directive. US towers
recommends replacing the cable every three years.
Most wire rope is lubricated during manufacturing. Lubrication does two
things:
Reduces friction as the individual wires move over each other.
Provides corrosion protection and lubrication in the core and inside wires
and on the exterior surfaces.
If I owned a crank-up tower I would keep the cables lubricated and only
change them if there was noticeable corrosion or broken strands .

I am missing something here as US Tower advises against lubricating cables.
What are you gaining by lubricating cable? I my opinion if a un-lubricated
galvanized cable shows signs of rust, it is time to replace it.
