What is the primary purpose of a rigger in crane operations?

The primary purpose of a rigger in crane operations revolves around the safe and efficient preparation and attachment of loads for lifting. This involves several critical responsibilities, including selecting appropriate rigging equipment, determining the center of gravity of the load, and ensuring all rigging gear is properly inspected and used according to safety protocols. The rigger must understand the loads they are working with and how to secure them in a manner that minimizes the risk of accidents during lifting and transport.

While ground communications, crane operation, and monitoring weather conditions are all important aspects of crane operations, they are not the principal focus of a rigger's duties. Ground communications are typically handled by a signal person or operator, crane operation is specifically the responsibility of certified operators, and monitoring weather conditions falls under the purview of site safety and operational assessments rather than the rigger's main tasks. Therefore, the rigger's integral role in preparing and securing loads is vital for the overall success and safety of crane operations.
