Found out my old man's rig chart numbers were off by almost 3 percent and the fix took me one phone call
I was flipping through a load chart at the yard in Bakersfield last Tuesday and noticed the capacity on the 40 ton for a 60 foot radius didn't match what I had memorized. Called the manufacturer's tech line and the guy told me the chart had been updated back in 2019, and my copy was a printout from before that. The numbers were off by just under 3 percent at the far radii, which sounds small until you're picking at 85 percent of chart. I reprinted the whole set, logged the change in our binder, and had the crew initial it so everyone's on the same page now. Feels good to catch something like that before it turns into a problem on a job. Anyone else keep an old chart in the cab out of habit? Might be worth a two minute check before the next shift.
