[TowerTalk] How to apply lube to HDX589

[Bert Almemo]

If you used a locking device on each section cables wouldn't be such a big
issue and would last a lot longer. Many european crank-up tower
manufacturers use locking devices on their towers. Versatower in one of
them.

How come US mfgrs don't use the same devices? Has anyone asked the US mfgrs
why they don't use section locks? Maybe someone can pick up on the idea and
make aftermarket locks? There is definitely room for improvement!!

Locking each section would dramatically increase safety and you wouldn't
have to read about towers coming down killing people and damaging equipment.
OMHO!

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!
