What specific risks do you feel your exposed to by remaining attached to the ball that your not already exposed to durring normal crane removals?
It's a case by case scenario, and the specific dangers would depend on the specifics of the tree involved, and the individual pick, as well as the carrying capacity of the crane. Without getting into that, all we can talk about is generalities.
As a climber, part of me loves crane work. It's quick, technically pretty simple even with complex rigging scenarios, and just generally less work. You make good money, with less effort. But another part of me hates crane jobs. You're putting a whole bunch of eggs in the one basket.
If I'm stayng in the tree, I have some control over what is going to happen, to me. I follow the practice (for better or worse) of keeping my head below the cut, so if the pick kicks or inverts I'm not going to wear it. I can also position myself in the tree so that I'm well shielded in the case of an inversion. I've been swatted, as I'm sure anyone who does crane work has been. But they've been fly swats. I also try where possible to give myself an escape route. I use 2 tie in points - flip line, and rope. I try to set it up so if If I see something going wrong with the pick, I can get the hell out of there, real fast. If I'm riding the pick, I can't get off that ride, even if I want to.
Since I don't own a crane, I have less control than someone who does. The whole issue of how the rigging is going to be set, and where, how big the pick is going to be etc, is a negotiated aspect of the work when you sub out the crane part. Generally, everyone (crane op and climber) has the right to say 'no', but as the climber you don't really have creative control. Maybe that's a good thing. Sometimes the crane op doesnt want to take the pick as I want it taken. What do you do then? His crane is on the line, but my life is on the line.
The whole justification for riding the pick, is that it's safer than staying in the tree. But my take, is that not riding the pick is always safer than riding the pick. #### riding the pick. If the tree is too dangerous to be in, then just slam it down and smash up whatever needs to be smashed. Or leave it alone and let it fall over whenever it does. Or use a cherry picker, or anything else. Get two guys in a man basket hung off that crane, and take it out piece by piece. I've used all those options at diferent times, and those are all safer options that riding the pick. Why add risk to an already risky job? To make it a little faster/cheaper?
If one of your climbers is one day killed riding a pick down, after doing a hundred jobs, or a thousand, would you say it was worth it? Don't stack the odds up against yourself any more than need be.
Do you want to be one of the alaskan crab guys who went just that bit further, for a few dollars more, and lost your whole crew? How much of a premium do you add to a crane job where the climber needs to ride the pick (if any), and do you share any of that premium with the climber above and beyond what you would normally pay them? If so, how much?
