What does "rigging" involve in the context of crane operations?

In the context of crane operations, rigging involves securing loads for lifting, which is essential for ensuring both safety and efficiency in operations. Proper rigging techniques include selecting the right type of slings, hitches, and hardware to safely attach the load to the crane. This process is crucial as it directly affects the stability of the load during lifting and transportation, preventing accidents and injuries.

Rigging encompasses various practices, such as understanding load limits, applying the appropriate rigging methods based on the shape and weight of the load, and ensuring that the load is balanced correctly. Improper rigging can lead to significant hazards, including load shifts, falling loads, or equipment damage, highlighting the importance of effective rigging practices in crane operations.

The other options focus on aspects that, while related to crane operation, do not specifically define the task of rigging itself—maintaining the crane pertains to upkeep and servicing, calculating wind resistance relates to environmental conditions affecting crane operation, and designing crane structures involves engineering processes rather than the practical application of securing loads.
