What's the protocol for crane lifts if the wind speed exceeds 20 mph?

Monitoring wind metrics is a primary safety standard. If sustained wind velocities or gusts exceed 20 to 25 mph, the crane operator or lift director has the absolute authority to shut down all hoisting operations immediately. Wide, flat-sided HVAC units act like giant sails in high winds, creating violent swinging forces that can tip a crane or smash the load into the side of the building.
