>  Now that I have a new crank up tower less than 3 months old,  what do you 
recommend I inspect regularly, besides the cable/pulley  integrity, winch 
operation and overall structure? What should I look for  besides the obvious 
signs of unusual wear? I also look at the antenna  mounting, rotator bolts, 
inv. Vee etc. every time I plan to have it  cranked down and folded over.

    That's about what you can inspect. Look for  damage, cable kinks, etc. It 
should be fairly obvious when you seen some.  

>  Is there some sort of lubricant that I need to apply to the  winch and 
especially the cables to assure long term  reliability?

Yes, you need a cable  lubricant that is light enough to penetrate the 
strands without leaving any  residual on the cable surface that'll attract 
contaminants. Wire rope  manufacturers recommend PreLube, available from _www
.championradio.com_ ( . 
        It's really messy so start  at the top of the tower and apply the 
PreLube on all cables as you work your way  down. When the tower is retracted 
blocked of course. 
        BTW contemporary pulleys in  some crank-ups use sealed bearings so 
there's nothing you have to do to the.
