Subject: [TowerTalk] multi-sheave pulley
<The trouble is, at age 77 I no longer have the arm strength that I once
<had. So, I would like to use a multi-sheave system to reduce the force
<necessary to lift it off and reinstall it. I have a two pully system which
<would reduce it to half, but I think I had better go with a three or four
<section system.
<All this to ask what is a good three or four sheave fully? It only need be
<a two inch diameter. Or, a one inch would work also. If you have any
<knowledge which one and where to get it, it would be appreciated. In the
<meantime, I will do my own searching. But, I thought it would be good to
<have the input of someone who has actually used what they recommend.
<As always, I look forward to the excellent advice that comes from this
<group.
<73,
<Dave, K4TO
### Use a ....cumalong. Easy, and much better control vs a lawn tractor.
http://ds-studio.co/cumalong-tool/ The 1st pix, is the version I have.
It has
the 2nd hook option..... so you double up on the cable....so its
only half
as long, but capacity increases from 1 ton to 2 tons. You then also
get
an even finer adjustment for a given amount of lever pull. An 88 lb
rotor
would be a piece of cake.
## I use a multi sheave / rope setup to get a yagi to top of tower,
then the same
cumalong to do the last few inches. Grnd crew lifts yagi up to top
of tower, then I
hook the cumalong to a 2nd quick rls shackle. Grnd crew then goes
home. I lift yagi
the last little bit.... then....using my hb version of the infamous
F12..easy on mounting
scheme, mate the horz boom plate to the already installed vert mast
plate.
