I have purchased all of the item to build my gin pole but I have one question I am hoping
someone can answer. I have two seven foot pieces of 2" x .250"
aluminum that I am going to use for the gin pole itself. I also have a
6' length of 1.750" aluminum that I am going to use for the connector
for the two 7' pieces.
Now my question is this; how long should the 1.750" piece of aluminum
be for the slice of the 2" pieces? I think having 3' in each of the 2"
pieces is
overkill and will add weight to the device. I was thinking more along
the line of 4' section which allows 2' in each of the sections. Or
should I go with 3' on each piece?
Having worked with these things for years, I wouldn't use a 2 piece gin
pole except for very light work. 2nd I would consider the smaller
inside splice to be too short. The first question is what alloy and
temper is the tubing and splice?
I use 12' and 24' sections of 6061T6 with 1/8th, 3/16 and 1/4 inch wall
depending on the load.
I would ask an engineer about the configuration you are planning.
Climbing and using gin poles in tower work is quite dangerous!
Every year we lose a number of well trained and experienced climbers.
When something breaks up there your only thought is to get out of the
way with out getting off the tower.
Working on a 40 or 50 foot tower can be just as dangerous as working on
the big ones. You are just working with smaller stuff which can be just
as deadly as can a fall from that height.
Be careful
