Lost half a morning to a simple reeving mistake on a Grove RT

I was working a job downtown last Tuesday setting AC units on a roof. Got the Grove RT650 all set up and started lifting but the load just kept swinging bad. Took me almost 4 hours to figure out I had the reeving wrong on the jib. I was running it single part when I should have been double part for that weight. My foreman walked over and spotted it in about 30 seconds. Felt like a real idiot standing there while the whole crew waited. Has anyone else wasted a whole shift on a rigging setup mistake that should have been obvious from the start?

Oh man, that hits close to home. I spent a whole afternoon once fighting with a boom truck because the lift kept binding up. Turns out I had the wrong size wedge socket on there and it was pinching the line. My boss walked by, grabbed a Big Gulp, pointed at it, and just said "swap that out, dumbass." Took him less time than it took me to get the coffee started. You're not alone, we've all been there.

Three quarters of an inch. That's all the difference was on my crane once. I was fighting a load that kept swinging no matter how I set the outriggers. Turned out the boom angle sensor was just barely out of calibration, enough to make the computer think the boom was longer than it was. Another guy on site just tapped the sensor with a wrench and said "try it now." I felt like a complete idiot but hey, at least I learned to start with the little stuff first.
