Here's the real story (siting from memory off of Agtalk from a guy from Kansas)
The driver didn't curl the arm and bucket under the boom, and lay it flat on the deck. He instead left it like you see at construction sites. Bucket flat, and and the arm straight up and down.
Not the first one I've seen along that same theme.
Some years ago, a driver for WH out of Wausau, WI said he'd hauled all sorts of flatbed loads. They gave him one that was both over-width and over-height. At an overpass where the "HIGH-POLE" in front of him tried to tell him on the radio that the clearance was too low, she finally realized he wasn't slowing down and nearly did a wheely getting out of his way. After he hit the overpass, she went to his truck and opened the door. His CB was off and the stereo was rattling the windows.
Not exactly the thing to do when your load is oversized.
It's still f-ing funny to see the pics though. People don't believe me when I tell'em that those Ex's can nearly take down a bridge without any help until I show the pics.
Might have cleared the bridge had the boom not been for dredging silt ponds and stuff. That's a much longer boom than the normal Ex's have, because of that, it was sitting much higher up since the fool apparently didn't clear the bucket in tight.
