the real reason that crane tipped: nobody on the crew knew what they were doing
ANYBODY on ANY job can shut the job down for ANY reason, unsafe cribbing? shut down till the issue is fixed
outriggers on soft ground? shut down till larger pads and cribbing are in place
about to make a cut that looks too heavy? shut down till a decision has been made, there are reasons the green log weight charts exist, you can get a fairly accurate idea what your piece will weigh before it comes off, due to the possibility of dynamic loading you shouldnt be trying to get to 90%, hell 50% is high enough to be dangerous
if the crane operator cannot see the climber, and the piece being cut, then use comms, or send the crane home, unsafe to do otherwise
crane operator has no clue what is going on at the hook because there is a house in the way? comms, or send the crane home, can always piece it out from a lift or climbing
always cheaper to refuse a job than it is to drop a crane boom on a house
there, I said it, if you cant do it safely walk away, no reason not to, even with insurance the odds of losing money are way higher by risking it
