Crane Signaling & Rigging
Crane signaling and rigging refer to essential practices in construction and heavy lifting operations. Rigging involves preparing and securing loads with slings, chains, and hardware to ensure safe lifting by a crane. Crane signaling uses standardized hand or voice signals to communicate between the crane operator and signal person, ensuring precise movement and placement of loads. Both practices are crucial for safety, efficiency, and preventing accidents on job sites.

❓ Frequently Asked Questions
What is crane signaling?
Crane signaling is the system of standardized hand and voice signals used to communicate between the crane operator and a trained signaler or rigger to coordinate lifts safely.
What is rigging, and what does it involve?
Rigging is the process of preparing and securing a load for lifting with equipment like slings, chains, and hardware to ensure the crane can lift it safely.
Who should perform rigging and signaling?
Only trained, qualified personnel: a certified rigger for rigging and a certified signal person; the crane operator should follow the signals.
What standards govern crane signaling and rigging?
OSHA crane-safety regulations and ASME B30 standards (the ASME B30 series) cover signaling, rigging requirements, and equipment inspection.
