Re: [RE-wrenches] 100 Foot Skystream tower

[Roy Butler]

Dana, Could you tell me a bit more about that 100' tower? The last I knew, SWWP only offered a 70' tower. So this would be a 3rd party tower? Xzeres (formerly ARE)? Or LMW&S? And is that schedule 40 pipe or schedule 10? Did you install the concrete foundations? Since you've installed some tilt towers before, I would imagine you understand the importance of having the foundations line up correctly. For this reason, I hate finishing a tower installation someone else started! I've seen as much as a 6 foot difference in elevation between the two side anchors on owner installed foundations. Under ideal circumstances and on that mythical frictionless plane, I'd allot 1 day with 3 people for assembly and another day with 4 people during the initial raising of the empty tower and the final raising with the cherry on top. Having a side spotter on these towers is invaluable! The trick of course is knowing all the unknowns before hand ;-) Roy Butler NABCEP Certified Solar PV Installer® NYSERDA eligible PV & wind installer PA Sunshine Program Approved PV Installer Four Winds Renewable Energy, LLC 8902 Route 46 Arkport, NY 14807 607-324-9747 www.four-winds-energy.com Although no trees were killed in the sending of this message, a large number of electrons were terribly inconvenienced.

I have done 100’ tilt up towers in the past but not for this size of a wind generator.   If so, how many man-hours would you allot for the assembly of the tower on the ground and raising? Assuming all goes smoothly and a worst case. I am aware of having to 20’ - “gin-pole” the 50’ gin-pole, and have several tractors to move the pipe around.     Thanks,  Dana Orzel   Great Solar Works, Inc E - d...@solarwork.com V - 970.626.5253 F - 970.626.4140 C - 970.209.4076 web - www.solarwork.com   "Responsible Technologies for Responsible People since 1988"   _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
