Hi All:
I concur the 8 ft versions are Heights Tower Systems. There are two versions
of the sections: those made before ~1995, and those made after. The earlier
versions are nearly identical to the Universal, and are limited as to load
capacity. The new versions have been re-designed per the UBC and can handle
quite heavy loads. The joint method can be in two forms also: using inserts
(similar to the swaged joints of the early version) and outside sleeve type.
I prefer the outside sleeve type because they are likely to be easier to
take apart after a few years.
I have one of the new ones (replaced an old one I had for 30 yrs). It is 77
ft (72 + 5 ft Fold-over base)and will support 35 sq ft projected area
antenna (per PE calcs for my 70 mph wind zone).
73s
Bob, W5LT

Same trouble here, but I put a spray tube on the nozzle and then only
release enough pressure for the stuff to come out in a stream. I hold the
tube against the cable where it goes down the hole into the telescoping
section. Then I spray until KD7DQO or FYX at the bottom tells me "It's
dripping!". I hope that means that the lubricant has run down the cable to
the pulley area. On the middle section, I have DQO or FYX crank it up while
I'm at the top of the bottom section (the tower is mounted against the
house) and spray the lube on the cable as it's being wound in.
I'll let you know in another five or six years if that works :-)

You are lucky to get 7 years out of the cable in HI. P49MR in Aruba broke
two cables in about four years. The manufacture recommends replacing the
cable every three years. I had a UST 89' tower for 4 years and while it
made a lot of squeeking noise the cable never broke. I never changed it due
to the amount of work need to do so. The LXC Prime Directive is to "DO
what the manufacturer says", but it seems that even he takes exception to
this maintenance procedure.

Subject: [Towertalk] Tubular crank up tower rope/cable lubricating
I have had two UST MA-550's over the past nearly 11 years.
The wire rope (cable) on the first rusted through after about
7 years in our tropical weather here on Kauai. When the
tower "collapsed" the force was so great that the boom of
my C4 snapped at a U bolt at the mounting plate, and the
tower sections broke through their "stop" plates essentially
destroying the tower as far as use was concerned. So I
got a new one. However, the old tower was salvaged by
one of our club members who is handy with welding, etc.;
it is now converted into a portable, two section crank up
used at Field Day and similar club outings here on the island.
(Photos of both the new tower, and the old converted tower are
at: http://www.karc.net/Activities/Photokh7m.htm ) the old
rehabbed tower photos are at the page lower left).
Never used any cable lube on that first tower. The cable broke
as I was raising the tower after having had it down for a time
during a spell of higher wind and rain. It was a cable area that
would spend all of its' time wound on the winch, and rusting,
when the tower was extended and most of the rope on the
winch. The length where the break occurred was only off
the winch when the tower was lowered, so it rusted when
wound tight on the winch.
On the new one, every two or three months (or whenever I
remember it) I now use Whitmore's "Wire Rope Lubricant",
which, per the can label, "penetrates to minimize internal
friction, increases wire rope life, and protects against
corrosion in all weather and salty environments."
However, I cannot get to the upper cable runs to apply.
The largest amount of cable is wound down on the winch
only when the tower is extended to its' full height; when
lowered, most of the cable is strung out and is DOWN
INSIDE the tubular sections, as is a good deal of cable
ALL of the time, or way high in the air on the outside of
the extended sections.
So, I spray on the rope lubricant to the cable wound on the
winch when the tower is up, and much of the cable is down
on the winch.
I have tried wetting a sponge tied to a long pole; then
raising the pole high in the air, attempt to rub the wetted
sponge up and down the extended cable up there. Does
NOT work well, hi. The pole sways about, and the few
moments are brief that I can hold it (in the prevailing trade
winds) against a section of the extended cable!
So, a fair length of my new wire rope cable has never been
lubed since set up. However, I am not too concerned about
this as it was the cable down on the winch that rusted through
and broke on the old tower set up. The extended cable seems
to dry quickly enough following our frequent, but brief showers,
that it does not corrode as does the wire rope wound tight on
the winch, where the water cannot evaporate away rapidly.
Anyone have any ideas, or how do you lube your crank up
cable high and inside the tubular sections?

CORRECTION
All but one who e-mailed me or called me said they did get base instructions
but nothing on the tower
as to a manual. This makes the towers useful but lacking in documentation.
Where is Lou Tristao when you need him?
I have a letter (5 years old now) from Bruce at UST. He says to contact the
dealer or installer for the mundane (his words) tower particulars.
As I said earlier get a concrete contactor and now a tower installer who
knows what he is doing!

I find this hard to believe. When I purchased my lawn ornament, US Tower
was so efficient they sent the installation instructions and just about
every piece of paperwork several months ahead of receiving my tower. With
that said, I am quite qualified to accept any additional 55' US Towers here
in Upstate NY because I have the instructions to handle such items.

I'm puzzled as to what kind of instructions anyone needs for a tower.
Isn't buying the correct base and installing that in the prescribed hole and
amount of concrete all we really need to know?
I've put up an awful lot of towers without any instructions; not sure what
I'd do with instructions if I had any.
I take that back. My refrigerator, microwave oven, washing machine, and
even my pool sweep came with instructions, and I still have them, somewhere,
in the cute plastic covers they came in. So, I can sell any one of these as
"complete with brand new instructions, never opened."

I suggest a nice coating of lithium grease in the joint to help slide them

Also i suggest stainless steel bolts. The galvanized ones tear up the
