> I was wondering if anyone had any opinion on lifting the final section
of
25G, top stub and thrust bearing installed, along with a 30 pound mast
nested within the section. My gin pole utilizes a 12? length of 6061-T6
aluminum, 2? diameter, 3/8 wall thickness. The combines weight of the
the
assembly is close to 80 lbs. The gin pole has been very sturdy during
individual section lifts, but I don?t know if #80 is pushing it.
The 25/45G ginpole is rated for 45G sections which are 70# each so no
problem on the lift weight.
In my experience (over 240 ham stations worked on) the problem is more
a matter of trying to do too many things at once. The LXC LAW OF LIFTS is
that each lift should be broken down into bite-sized chunks so that you're
not trying to do 2 or more things at once. Examples are lifting an antenna
with coax attached and lifting a tower section with mast installed. In the
first case, the coax will inevitably wind up going around something you
don't want and you might have to remove the coax to get it where you want it.
The consequence of violating the LXC LOL is that you typically will have to
change your plan, re-rig and try it again.
If you pick the section and mast together, you'll have to have the
pick point high enough so that the load won't tip over which means that once
the section is in, you'll have to climb up the mast to disconnect the haul
rope - a maneuver very few people can accomplish.
GL in any case.
