Chris's mention of Barenco (same as Jaybeam?) couplers leads me to say
that it is utter madness for someone to stand 'at the base of the mast'
- I have seen pictures of a mast being raised with a gin pole, with
someone at the base. If a coupler fails or even if a side guy gets over
tight, that is an extremely dangerous place to be. You could easily be
killed or badly injured. There is no need to be there, the joint between
the mast and gin pole will dig into the ground.
I always refuse to raise a mast until everyone is outside the circle of
the guys. It just isn't worth the risk. And yes, I have seen a coupler
fail in this situation. It was a Jaybeam one, with that stupid
indentation which weakens the coupler considerably. The thing tore in
half. One fix to prevent this problem is to weld a spine along the
length of the coupler, but this is still no reason for anyone to risk
their life by standing at the base. Just think about the forces acting
on that point.
