[TowerTalk] Legs of a 60' piece of tower being dragged while being lifted

[StellarCAT]

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 the crane as it would need to boom out too much... with hindsight I might have tried to do it differently to accomplish this better but even thinking about that I don’t think it would have been possible with 6 antennas all assembled scattered around. The space where it would have had to go is where I had to stage the 50’ boom 5 el 20 in order to get it pre-assembled on to a 14’ tower section – it and the 80/75 dipole are at the top and I had to use that space to get it ready (its now done and ready to go).

I may be all wet here, especially since I have never done this before, but it seems if you position the base of the section you want to lift near the tower you want to lift it onto then swing the boom of the crane to pick up the end, as you pick it up if you swing the boom back towards the base of the section you're lifting there would be very little dragging involved. 

Again without having real life experience at doing this I may be completely off-base but just a thought.

  So Fred pointed this out ... I hadn’t considered it up until then... is it a problem to just allow the legs drag in the dirt while the 60’ piece with rotating ring attached (~850#) is lifted? Is there ANY chance the legs will deform making it impossible to mate it to the tower? I don’t have access to an end loader or any other piece of heavy eqmt ... I thought, and this might sound silly, a dolly ... those cheap(er) ones – seem to be rated at 600# ... if I could get enough guys to lift the end and put that under the end – then we could pull it along as the crane goes up.... although the ground is really rough so that is doubtful... it would probably get stuck and the legs drop off which would be far worse than just having them drag on the ground ... experiences anyone?
