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!
