Yes, environment matters and should be taken into consideration for any 
maintenance.
Yes, a free standing tower doesn't have this issue -- but then those of us who 
do have crank-ups usually do for a reason.

I am sure that even with no maintenance the cables will last significantly 
longer than three years in most installations. Cable breakage can  destroy 
your tower and antenna so this is something that needs to be monitored.  If 
you are in a corrosive environment the cables may not last three years. 
P49MR had the cable break twice on his U.S. crank up tower and I do not 
think that they lasted even three years in Aruba  A few years ago he 
replaced the crank-up with an AN Wireless free standing tower and has had no 
problems since.

Well I never heard of a crank up tower that failed because the cables were 
not lubricated PROVIDING manufacturer guidelines are followed and cables are 
changed when required.

I think we as hams tend to both try to reinvent the wheel too many times. If 
it ain't broken, don't fix it!
