Look at KF7P.com

We recently installed one of his products to motorize a an older Tristao 72 foot crank-up.

Cheers,

Re: MA-550 Max allowable wind area?

Al Ludwick / NN4ZZ
 

Hi Kent,
Back when the MA-850 was sold in the 80's the wind rating was 10 SQ FT, see pic below.  They have changed the ratings over the years and downgraded them.  

Also back in 2004 I asked about how nesting the tower would affect the ratings....here is the reply.

Al,
We are delighted to hear that you are enjoying your towers. It great to get feed back on our towers.
 
We do not have any data on the different wind ratings at different heights.  The engineer has given me a rule of thumb, that for every twenty feet that you lower the tower the wind loading should increase by 20%.  
 
I hope this information helps.
 
Thank you for your interest in US Tower Corporation.
 
Sincerely,
Gary Smith
US Tower Corporation




Hope this is helpful and maybe others will chime in with more current information on the new standards.

MA-550 Max allowable wind area?

Kent Olsen
 

I am buying a used US Tower MA-550. I am looking at the Structural Analysis Report. The Max Allowable Wind Area (sq ft):1.4.

The antenna I am thinking about putting on it is Wind Load – EIA-222-F/G* 7.9 sq ft / .73 sq m and Wind load – EIA-222-C* 4.4 sq ft / .41 sq m. 

What are the different figures??

Hi Adam,


It looks like a nice unit that may be adaptable to a few different towers.  It would appear from the markings (AMS) that Aqua Marine Supply makes the unit.  If Heights isn't helpful with providing the particulars, you may take a shot at calling AMS directly.  Their info is at the bottom of this page: http://www.heftyhoist.com/index.aspx

Hi,
Can anyone tell me if this hoist by Height towers will be ok to use on my US tower Tx472 .

Telescoping Towers


I know it cost $1328 but still less then 5k for one from US Towers, also I don't want to use cheap $200 hoist since this is too fast to raise and lower tower like mine.
I looked many sites and this option from Height Towers seems to be very easy to attached to my tower .
Thanks

Thanks for the response Larry. I am looking at a lightweight solution for a client who has no vehicle access to the back of his house where we plan on installing a crank up tower and his XYL told us that we will for sure find out if there is life after death if we damage her lawn, so I am going to look into an Aluma crankup since they are light enough to carry over the lawn.

I don't know what today's price is but in 2001 mine cost $7665(rotor plate, thrust bearing, ground mount post and motorized winch)

I have had a C31XR and then a 4el SteppIR with loop on it. I think he was asking some about a Mosley ??53.

I agree with Larry, K1ZW, the Alumatower is the way to go. I have had the T40HN for a couple years and it is a great tower. I mounted it with the MP-2 ground pole without cement. I dug a 6'6" deep hole about 24" wide with a shovel and sop-vac and dropped the MP-2 into the hole. Then filled the hole with dirt and a little water to pack it down. It is as solid as anything I could get with cement. Tower survived near direct strike by Hurrican Irma last year. I lowered it and then tilted it over. I placed a couple ground screws into the ground and used a couple ratchet straps to secure the tower to the ground. It went right back up into service as soon as the wind was over.

Aluma Tower was great to work with and has provided me with a great tower. My wife and I picked it up at the factory in a Uhaul. We then were able to take it out of the truck by ourselves, it is that light. The perfect tower, easy to install and maintain.
