Pro tip: a talk with a bridge inspector changed how I think about wind
I was working on a site near the river in Portland last week, and a state bridge inspector came by to check our setup. He pointed at my crane and said, 'You know, the wind doesn't just push. It grabs and shakes once it gets a hold.' He showed me his data from a sensor on the bridge, and the gusts were hitting 5 mph harder at 200 feet than what my ground meter said. I always trusted my little handheld anemometer, but now I realize it only tells part of the story. I'm looking into getting a second, higher-up sensor for the boom tip after that chat. Has anyone else found a good way to get a better read on wind speed up where the load actually is?
