That's what they're looking for. By doing that, I'm gaining their trust in letting me fly this stuff over their heads. The crackle of the radio is a crane operator's constant companion. The rigger is the usual voice on the other end. The rigger and the operator speak in a coded language that is both consistent from job to job and personalized between the two people doing the work.
Verbal communication is all-important.
You have to trust your rigger, especially when you can't see the loads. He guides me in to exactly where I need to be. I have to trust him on what I'm picking up and how much it weighs. He wants the hoist lowered about 6 inches. That's the dog.
