Just last week, I put up a pier pin base Rohn 25 just about that way.
While waiting for my helper to arrive, I attached the temporary guys to
the top of the first section. A second set of ropes were attached to the
anchors, and loosely tied to the middle of the section. I then stood the
section on end, lifted it onto the pier pin, and tied the lower ropes
onto the tower. That kept it upright until I went around to the anchors
and tightened the main temporary guys. When my helper arrived, we were
ready to put up the gin pole and install the second section.
I wouldn't try that alone with Rohn 55, of course.
