What is often used to provide communication during crane operations on a busy site?

Using both hand and light signals during crane operations on a busy site is essential for maintaining clear and effective communication, ensuring safety, and coordinating movements. Hand signals are universally recognized and allow for direct, immediate communication between the crane operator and ground crew, especially in noisy environments where verbal communication may be impaired. Light signals enhance this communication, particularly in low visibility conditions or when distances are too great for hand signals alone. Combining both methods provides an effective system for guiding operations, mitigating risks associated with miscommunication, and ensuring that all personnel are safely coordinated during operation. This dual approach is critical in busy environments where multiple activities may be happening concurrently.

While walkie-talkies can also be used for communication, they may be subject to issues such as battery failure, signal interference, or user error, making them less reliable in certain situations compared to the visual nature of hand and light signals.
