If more of these so called rigging companies would learn how to use one of these on their cranes and understand whet the weight means with the boom extended as they do then possibly there would be fewer OS moments
Never try to tell me it can't be done

...but we did have a really bad incident one time with crane that dropped the headache ball because of a bad limit switch. That was pretty crazy actually. It hit a piece of steel that some guy was standing on. It turned his leg into jello. He was in hospital for at least 6 months (probably a lot longer) while they tried to save his leg. I'm still not sure whether he got to save his leg or not. If he did keep it he's probably in pain every minute of his life.
