Hand signals are used to transmit instructions from a spotter on the ground to the crane operator high above. Here is a poster illustrating those hand signals, courtesy of the California Crane School. Feel free to post it at your job site, or to have any of the images tattooed onto your forearms.

Cranespotting (Geocities) ... is the compulsion, upon seeing a long crane boom reaching skyward in the distance, to drive over and see what's holding it up. The crane capital of the world is Germany, where Demag, Gottwald, Krupp, Liebherr and others make some cranes with eye-opening numbers: more than 60 feet long, with 10 axles, and able to lift 1,000 tons. Now sometimes cranes tip over, touch power lines and so on; and there's a website for that too.
