I have a very heavy duty tubular tower for sale that would be an excellent wind turbine tower.
It is 1/4 inch wall tubular steel, has 3 sections that range from almost 1 foot in diameter to around 5 inches in diameter and is telescopic and tiltable. The telescopic feature could be removed and it could be made into a rigid mast if the ultimate strength is required.
It is free standing or guyable. It can rotate in its base on a bearing surface or be locked into one position.
The bases are 1 inch plate steel and connect to the concrete with 16 one inch rebar locations.
It is Mil Spec and will meet or exceed TIA/EIA-222 F & G Specifications and possbly even more stringent standards. It was basically designed to withstand a blast. I have contatced an engineering firm that will map the unit and design a footing schedule and strength analysis report for your State and County if you need this certification for your application. They will charge a fee for this service if you require it.
Many extra elecronic components come with it such as a motorized Braden worm drive gear reduction winch system, heavy duty industrial motor reverser, Eberhardt-Denver gear reducer and more that may be resold by the purchaser if the telescopic feature is removed. Also 2 tiltover mounting bases are included.
It is galvenized steel and can be painted "wind turbine white" using industrial coatings specially formulated for use over galvenizing for an additional $175.00
