Kurt,
I have emailed you direct the only relevant document you will ever get out
of US-Towers, it took me three weeks and a personal visit to get that. Wind
calcs, base tension/compression calcs....you're on your own, if you managed
to get the stuff that Steve mentions below from US-Towers it would be wrong
for your city/county anyway.

Contact US Tower's customer service and tell them you need the Installation
and Maintenance Instructions and also the Formal Stress Analysis Document
for the MA-40/MARB to complete a building permit application before placing
an order for the tower.
Most of their tubular telescoping towers are only rated at 70 mph
fastest-mile method (old TIA RS-222-F spec) . If your local building code
requires 90 mph 3-second average (current TIA RS-222-G), you may be out of
luck. I have an MA-55 and haven't had any luck getting an updated stress
analysis. (70 mph fastest-mile = 85 mph 3 second gust, so it's not a huge
stretch to 90 mph.)
And their installation and maintenance instructions won't impress you
much....

I'm in the planning phase of putting up a used US Tower MA-40. US Tower
keeps sending me the generic information every time I ask. Can somebody
please point me to a resource of where I can find the documentation that
came with the MA-40/MARB when it was new?
