A 30 year guy at the yard said always check your wind sock before the load chart, saved my butt on a 180 foot pick in Tulsa | Crane Operators - Babble Community
Man, that old timer wasn't kidding. Wind will change your whole math in a heartbeat, especially on something tall like that. I've seen guys get so locked into the load chart they forget the wind is gonna eat into their capacity whether the chart likes it or not. Gusts up top on a 180 foot boom can kill a pick that looked fine on paper. Check the sock, check the trees, check the flags on the fence, then look at your chart.
