What signal is often used by riggers to communicate during lifts?

The use of hand signals by riggers during lifts is a common practice due to their effectiveness in ensuring clear communication in noisy environments. Hand signals are crucial for safety, as they allow riggers to convey important information to the crane operator and other team members without relying on verbal communication, which may be difficult to hear over the sound of machinery or in windy conditions.

Hand signals are standardized, which means they are recognized across the industry, reducing the potential for misunderstandings. This visual method of communication allows for immediate feedback and coordination, enhancing awareness of the lift's progress and any necessary adjustments.

While other forms of communication, such as written instructions, radio communication, and sound alerts, have their place, they might not provide the same level of immediate and clear understanding that hand signals offer during the dynamic process of lifting.
