Why 32km wind speed is fixes as a level to stop the crane rigging activity?

A wind speed of 32 km/h is often considered a threshold for halting crane rigging activities to ensure safety and stability. At this speed, winds can create significant forces on the crane and its loads, increasing the risk of tipping, swinging, or losing control of the load. Stopping operations at this level helps prevent accidents, protects workers, and maintains compliance with safety regulations. It is a precautionary measure to mitigate risks associated with adverse weather conditions.
