Check out http://k7nv.com/notebook/id7.htm for an analysis. btw the Rohn pole is 0.125" 6061 wall and rated for 45G @70# per section.

Never use a pole as a tram tie off or pull at an angle against the pole.

I was wondering if anyone had any opinion on lifting the final section of 25G, top stub and thrust 
bearing installed, along with a 30 pound mast nested within the section.  My gin pole utilizes a 
12’ length of 6061-T6 aluminum,  2” diameter, 3/8 wall thickness.  The combines weight 
of the the assembly is close to 80 lbs.  The gin pole has been very sturdy during individual section 
lifts, but I don’t know if #80 is pushing it.
