I haven't work with a crane much. So my experience is limited. Yesterday we were removing three large eucs with a crane. I rode the ball up and put on a strap. That was cool, then my boss on the next tops wanted me to hook my climbing line on the ball, put the strap on then lower my self from the ball make the cut and let the crane lift me and the top off at the same time. This seemed kind of crazy to me. I was game to a point, but vary uncomfortable to say the lest. The crane operator refused to let this go down after I was up in the tree ready to make the cut. Did my boss try to get me killed? He said that's how he use to do it all the time.
