Spent 4 hours chasing a load chart error that turned out to be one dumb thing
Last Tuesday at a job site in Fresno I was setting up a 60 ton rig and the load chart kept showing I was over capacity on a pick I knew was fine. I checked the outrigger pads, re-leveled twice, even called the rental company to see if the chart software was outdated, which ate up like 90 minutes by itself. Turns out the boom angle sensor was just caked in mud from the drive over, and a rag and 30 seconds of wiping fixed the whole thing. Anyone else had a sensor or computer throw off a pick when the real problem was way simpler?

Had the same thing happen on a 40 ton up near Stockton last spring, the LMI kept beeping at me on a pick that was well within the chart. I messed with the outrigger setup, checked the anti two block, ran through the whole startup again, probably burned an hour easy. Turned out the boom length cable was just gummed up with old grease and dirt and the reading was off by like 6 feet. Wiped it down and re-zeroed it and boom, problem gone. Now the first thing I do before I even start messing with anything else is walk around and look at every sensor and cable on the boom. Mud, grease, ice, a bent bracket, it all throws the numbers off. Nine times out of ten it's something dumb and physical, not the software. A rag and five minutes beats an hour on the phone with the rental yard every time.
