They were lifting concrete panels for the new flood wall. The operator had a spotter using colored flags for each direction, which was new to me. It looked way smoother than just hand signals. Could be a good idea for sites with lots of background noise.
It's amazing how much difference a few daily huddles can make.
Always refuse to cut corners on safety, no matter who asks.
I was lifting an AC unit to a roof when my walkie quit. I made up some big arm signals to chat with the ground crew, and it actually went smooth. What's your backup plan when tech fails?
