Like they always say, you get what you pay for. Does sound
really great. I wonder what kind of features they have for
dealing with multiple coax and rotor cables? They must have ways
to wind up and feed out the cables when raising or retracting
the tower. Jim WA6EKS

Jim, The Luso engineer only has to be present when the tower is
being
installed, not for the base digging and pouring. However, copies
of all
permits, including soil studies and environmental impact
statements must be
submitted to Luso for their review and approval. My friend says
that
providing copies of all of the paperwork, along with soil and
impact
studies, costs several thousand dollars. There is nothing
inexpensive about
putting up a Luso tower. However, when it is all said and done,
you have an
absolutely top notch tower.

Alan, how large is the foundation for one of these towers? Does
the
engineer from Japan have to supervise the installation of the
base? Jim

The width of the bottom section is 65 inches, less than I would
have
guessed. Width of the top section is 18 inches. I don't know
what the foot
print of the rotating base is, but that may well be significantly
larger
than the first section of the tower itself.
Here is an interesting fact, when buying any of these towers, you
must pay
for a Luso construction engineer to travel to your station from
Japan, to
supervise the entire preparation and installation activities..
You must pay
all of his expenses, including airline tickets, hotel room, etc.
The reason
for this is to assure that the tower is installed correctly. My
friend that
just bought the 90 foot model, had to pay around $5 grand for the
engineers
presence.

heavy duty alright at around 15 tonnes...that sounds a bit on the
heavy
side? A heavy duty 68 foot del hi only weighs maybe 500 pounds
total...this
must be a very very large tower? that is, very large spread at
the bottom to
support so much weight at the top?
Obviously a 68 foot del hi is only rated for about 12 square feet
of wind
load though lol.
I can't imagine shipping on a beast like that haha.

Subject: Luso towers
Hello list,
Has anyone on the list looked into Luso towers when shopping for
a new
one?
For those that aren't aware of Luso, it is a Japanese tower
builder of
heavy
duty electrically operated crankup towers in heights from 90
feet to over
300 feet. They accommodate antenna, rotor, and mast weight of
up to 2200
pounds. The 150 foot model is rated to accommodate 140 square
foot of
antenna, and goes from a fully retracted height of 42 feet to a
fully
extended height of 145 feet in 29 seconds. Masts of up to 8.6
inch
diameters are accommodated with multiple thrust bearings. Each
model is
available with a number of options, including a rotating base,
and
automatic
retraction when winds exceed a preset level. The 150 foot model
weighs
29700 pounds excluding options.
A friend just took delivery of the 90 foot model with the
rotating base
and
automatic retraction system. Because of my recent good news on
the health
front, I am seriously thinking of ordering the 120 foot tower
with the
rotating base, automatic retraction, 4 inch mast with thrust
bearings, and
a
prop pitch rotor with Green Heron controller.
If anyone has investigated the Luso offerings, I'd appreciate
discussing
them with you.
Merry Christmas everyone, and a very happy New Year.
Best 73
Alan
