Two years of flying blind until a guy in Houston told me to stop trusting the load chart on the wall
I was on a tilt-up job outside Houston about two years back and got talked into a pick I never should have taken because the chart in the cab said I had room. An old hand named Ray walked the radius with me in the mud, made me measure it out to 62 feet instead of the 48 we'd been guessing, and the numbers went from fine to not fine real quick. Now I pace every setup off before I boom up, even on stuff I've picked a hundred times. Half the guys I run with say that's overkill and the chart plus a good spotter is plenty, the other half won't lift without walking it. Where do you all land on it, do you trust the chart and your eye or do you get out and pace it every time?

How many of you have actually read the fine print on those load charts? I got handed a manufacturer bulletin a while back that laid out how the chart ratings assume perfect ground, level machine, no wind, and a brand new operator who never bounces the load. Real world you got soft dirt, outriggers sinking a little, and a guy on the radio who says "you're good" from behind a wall. I started pacing my radius off after that, mostly because the chart in the cab tells you what the crane can do, not what the ground under it can hold. The old timers around here call it the difference between book smart and mud smart. I get why some guys say pacing is overkill, but you only get one chance to find out the chart was wrong.
