About a decade ago I acquired a little broadcast tower and am now wanting to put it up. There are eight sections, 20 foot long each, about 18 inches on a side, solid rod legs about 1.5 inches in diam

Hi Stan: I think its called a crane :-). I've helped put up several 25g and 45g towers in my ham career. The 45g sections usually required 2 if not 3 people to pull the section up safely. I'm sure so

Another thought. A gin pole hefty enough to handle that kind of load on a 20 foot section would itself be quite unwieldy to raise after each new section is put in place. Frank W2FCA List Sponsor: Are

A gin pole to handle this would be, by itself, quite a heavy and cumbersome item. Often a smaller gin pole is used to erect the main pole - which in many cases is a small tower itself. A lot of work

As you can guess, because you've handled the sections (too many times probably :-)), this stuff will require a good stout gin pole. 50' of Rohn 45 makes a nice gin pole for handling 20' sections of t

Hi all: Don't forget you `pick' a section a couple of inches from the center in such a way that it is balanced with the end YOU want down on the heavy end. This keeps you from having to fight the sec

Not neccessarily. The big 1000'+ broadcast towers are installed using 50' or 60' gin poles made out of tower (appropiately sized of course). They do not slide in a bracket, but simply get lashed up a

I agree that if you just need more beef on the pull rope, you can get more bodies to do it. But, I was addressing the issue of too much load on the gin pole and more bodies pulling on the rope doesn'

of course the lifting rope load remains the same, but the force required on the pulling end decreases so the total load on the gin pole does get reduced. for example, with a standard gin pole lifting

Steve, you are "half" right. The lift effort is part of the overall load on the ginpole (everyone forgets this), so without any mechanical advantage there is 2X load weight applied to the ginpole. If
