Mike,, I have been doing tower work for almost 30 yrs. First of all, those
Rohn gin poles
are a joke to me...They take too long just to move the pole from one section
to another.(clamps)
I made my own pole from 2 1/2 inch square aluminum thick wall. I have hooks
that are
bolted to the base of the pole. My pole will fit Rohn 25, 45, and 55 without
any adjustments.
The hooks utilize the angles of the tower.,,so that when in position to lift
up a section,,the
pole can not move laterally at all cause the hooks are riding down the
angles. It is critical
that the hooks bottom out at the same time to eliminate slop. ...So,, with
this situation, I
can send a section to the ground, lift up the pole and set it on the top of
the second section
down, and the rope will be thru the pulley atop the pole and tied off 1 foot
down from
the top of the section I am removing. My gin poles are 14 ft long. So to
get you the proper picture,,
when I send down a section,, if you looked up,, there would be 10 ft of gin
pole above
the tower,,and 4 ft attached to the top of the tower---then I have to move
it down and do it
all over again. I can move my gin pole one handed.--there are no clamps. I
could send you some
pics if you like... Dan N4GNR

Pulling each section down with a gin pole would require moving the gin
pole
down after each section removal. So wouldn't you need 2 clamps on the
bottom of the gin pole and then one mid way up to secure the gin pole when
lowering it down a section when lowing the bottom clamps?
Thanks,
Mike

Takes forever ??? I can not understand that...,, as long as there is
not rust in the joints, you should be able to get it down in less than an
hour
by gin pole. If you don't mind paying a little,, a bucket truck is
quicker, as
long as they can get close by the tower..Actually, my bucket truck
"basket"is rated for 500lbs,
and could pick up the entire tower. Other practices are to hinge the
base, or set pulleys
on a pole or tree and lay it down.. However, this likely may mess up the
base section at
ground level.. Your question needs more info on how the base section is
attached to foundation
for faster alternatives.
That would answer the overall best way to do it,, but gin pole is
quick...Good Luck,, Dan N4GNR

Howdy,
So I have erected many towers using a standard 12 foot gin pole, works
great, but takes forever. However, what is the best practice these days
for
removing a 50-60 ft Rohn 25 tower? Gin pole or is there an easier way?
Thanks,
Mike
