I have been thinking along these lines in a slightly different way. I
choose to call the traveling part a "tram". I have a forty foot
utility pole ready to plant but there is no way I will ever climb it.
It is a little more complicated because it is about 12 inches in
diameter at the bottom and about 6 inches in diameter at the top.

I envision something like an inverted crank up tower mechanism. I am
planning a long sleeve (3 feet?) pulled up by one or two steel cables.
As the tram approaches the top, vee notches in the upper end of the
sleeve will engage a big pin through the pole to align & stabilize the
horizontal position. The vertical positioning will be accomplished by
wedges length wise on the pole that do not engage the inner surface of
the tram until the last few feet of travel.

There is no new technology here so no patent issues. The choice of
materials for the tram is important, it must be strong but light as
possible!

If anyone is inclined to turn my idea into a commercial product I
would be flattered!
