Boy ... I hate I stopped reading all the post on this subject. I will
inject a comment on safety and hope that it has not been stated before.
The dead weight of #200 on the lift side is opposed by the #200 of pull
weight on the other end. This is true at rest. However it is very
important to keep the pulley in good condition and freely working. It
has been my observation (including my own) that most gin poles do not
get the proper maintence and the pulley assembly get worn and in poor
working condition. Due to this we now have to exert much more than the
#200 of pull to off set the dead weight of #200. The small size of the
pulley compounds the force needed to overcome the weight and mechanical
forces of the poor pulley assembly.
It is important to keep the pulley in good working order to reduce the
amount of force needed and thus the load on the entire gin pole. A
small factor but it can really increase the load on the gin pole.
I only wish I had learned more of my physics while in school ... at the
time I just could not understand when we would ever need such .... Hee
Hee .... :)
I hope to have a gin pole assembly that I am working on ready for
Dayton. Hope to see every one there.
