Anyone have an ideas regarding rails, rollers, general set-up, etc. that could be used for about 75 feet of 55G or 65G that would telescope into about the same length of larger tower (33 inch face, 3

Stan,   Homebrewing a tower especially a crank-up is a dangerous and risky proposition to say the least.  The ROI and the safety concerns is not worth the risk. In the end you will be better off buyi

Risky, yes without doing the calculations, but one of my goals for years has been to build a crankup and fold over, rotating mast that will go to 60 or 70' and support at least a 30 - 10 log and mayb

I don't know.. I haven't seen many 120-150 foot crankups in the HRO catalog recently. I have seen tower trailers with that sort of height, built on the base of a 40 foot semitrailer, but not as two s

Oddly, depending on how it's done, it might not fall under TIA-222. I don't think tower trailers follow TIA-222, for instance. It might be more like an extending boom crane, from a regulatory standpo

As sailors say "getting there is half the fun". Designing and building a track system is great for a real DIY'er. _______________________________________________ _____________________________________

If it's a crankup, I guess there's no guys. Rohn specs 70mph 0.8 sq ft wind area for 60' of unsupported rohn 55g Is that 15 lbs/sq ft? Even if you scale that back to 50mph, how can you get anything a

As mentioned the lower section would be large (33 inch face) tower with 3 inch diameter legs. The top would either be 55G or 65G. I'm interested in ideas for rollers, etc. Not worried about whether i

So the inside "diameter" of the lower section is about 27-30 inches? That's quite a bit larger than the outside dimensions of the 55G or 65G. You'll need to fabricate some sort of traveler that would

It doesn't matter whether you analyze the top section as if it started on the ground or on top of something else. It's the same analysis. right?. (except higher wind higher) "about 75 feet of 55G or
