[TowerTalk] Wilson Crankup Tubular Tower Info Request

Wed May 4 15:59:29 EDT 2005

Thanks Chuck, and to the rest of the towertalk list members who replied to me - this is just the info I was looking for. Unfortunately, the one I'm looking at picking up doesn't have the tilt over base, so we'll just have to try to wrestle it down from the upright position. I had hoped to put my 2-element quad on it until I get a bigger tower installed at my new home, then use this Wilson mast for something lighter like some VHF yagis, etc.

Thanks again,
Larry

Picked up one of these couple of years ago myself.  As
near as I could figure from the Towertalk Email trail,
the  Wilson is similar to the US Tower (UST) 55ft'r. 
Weight about 425lbs.  Mine came with the Tilt over
base so lowering it was easy.  It took five of us to
move it to one of the CostCo Garden Carts (amazing how
much these will hold).  We then pushed and pulled it
about 100ft to a 20ft car trailer for transport home.

I used the info from UST's 55ft'r to get a permit. 
The base info is on their website  Also HRO website. 
UST is now using 1 inch all thread bype rods (info on
the website), which I picked up at a local hardware
store.

Replaced all of the bolts I could get to and will
replace the winches soon.  FYI look a little more on
Towertalk and you will get some windload spec's -
after seeing these I decided not to put the extra ten
feet at the top and to only put a 2el Quad on it.

I live in Port Angeles, WA.  73, Chuck N7BV

I have a chance to pick up what appears to be a Wilson
crankup tubular 
tower from a local estate sale - it looks like it has
three - tubular 
telescoping sections. After looking through the
Towertalk archives, I 
think it must be a Wilson model MT-61 series. The
concrete base has some 
info scratched into it, showing that it was installed
in 1979. 

I'd be interested to know if there's a site with info
for the concrete 
base requirements, info for replacement threaded
rods/J-bolts to go in 
the concrete base, etc. What's the weight of the
tower? We're trying to 
figure out how to tilt this over safely after
releasing the upper house 
mounting bracket which is up about 10 feet above
ground, and determine 
how many people will be needed to safely lower it, how
to lower it, and 
carry it to a truck for transport to the new QTH.

I'm also assuming that the winch and cables will need
to be replaced. 
Any other major maintenance that would need to be done
for a tower like 
this that has probably been up for 25+ years in the
rainy Northwest?

I do have a bunch of .jpg pictures of it available, if
anyone has 
questions. 

Thanks,
Larry
