Hello, This is directed at those that have had direct experience with the use of a crane and a man bucket. My antenna/tower project, at least the major part of it (one of the two towers) is finally g

Hi Rich, Indeed the more I think about it the more I think the guys will be in the way of the bucket. I don't know how wide the bucket is - any one know dimensions on a typical bucket? 3 of the 4 ant

Hi Grant, I think the guys will be in the way of the bucket... I had been focusing on safety and how do you 'hold' the antenna and hadn't thought about proximity to the guys ... I think I'll forego t

Thanks Gerald ... indeed its 1/2 EHS and the 5/16 is pretty substantial weight ... theres also a 15,000# insulator in there as well... my guess is youre right that I wont be able to pull enough tensi

Ok, Another question: so I have this 60 long section of R55 with a rotating ring at the 48 point which will have guys hanging down from it ... the weight is probably around 850#. The tower is laying

I hope not! I had planned on lifting it from the top. No reason to do it from the side as it is when in place 135' and the crane is supposedly capable of 200' ... right? --Original Message-- From: R

That's what I figured! Didn't use the term - didn't remember it at the time but choker slings... wrap them so they 'grab' the legs equally and thus it should be vertical. The hook will freely swivel

Indeed you are correct ... however space is the limitation. The 60 piece was assembled with the top nearest the crane and going away from that spot that distance it goes away is probably too far for

Good point - one needs to know how the radio was 'calibrated' in its design... for the FTdx5000 it is using AMP1. One thing I like about the Flex6700 I'm testing... the S meter is always accurate. g.
