The second problem is there is a lot of friction in the pulleys. I've
seen tests for hardware store ones where the output tension is only
half of the input tension.
I can confirm that. When I put up my Rohn 25 last summer, I pulled the
rope to lift the sections. I can tell you it took a whole lot more than
40 pounds of tension to lift them. Obviously, the pulley on the Rohn gin
pole was not one of the good ones.
