Subject: [Towertalk] FK4564 Rohn Gin Pole
> For a Rohn 45 Foldover tower, the folding section weighs 100# and the Boom
> Section weighs 165#. They are very heavy on a Rohn45 Gin Pole and in both
> cases, the gin pole is only extended enough to raise the load to the
> required height. The Rohn gin pole is not designed to take any
> side loads.
> In previous discussions with K6NA Glen Rattman, he puts the 20 foot mast
> the tower after the first two sections are built and does it by
> a second 30 foot tower clamped securely to the first tower and uses the
> second tower to lift the mast, then tears that tower back down.
> Handling big masts is very dangerous work and for an amateur, the crane is
> reasonably safe way to handle it if the tower is already built. Working
> with a BENT 20 foot mast nearly always requires a crane to get it down.

> He further suggested a longer than normal ginpole.
> Placing a 100lb 20+ ft mast inside a 130' tower was

> K7NI points out that the Rohn 25/45 ginpole rating is for a 70lb
> section of 45G, so you're pushing it with a much heavier mast.
> The root problem is balance and leverage, and lifting height, and it's
> flat-out dangerous to pursue this with the top section in place.
> If renting a crane isn't in your budget, REMOVE THE TOP SECTION OF
> THE TOWER.
