What is the minimum swing clearance required for a crane's boom and counterweights?

The minimum swing clearance required for a crane's boom and counterweights is typically established to ensure safe operation and to prevent collisions with nearby objects, personnel, or other equipment. The correct answer of 2 feet is based on safety standards that take into account the movement of the crane's boom during operations. This clearance helps to mitigate risks associated with sudden movements or swings of the crane, allowing for adequate space to maneuver safely around job sites.

Safety regulations often specify minimum clearances to ensure that any unforeseen circumstances, such as wind or operator error, do not lead to a dangerous scenario where the boom or counterweights could strike someone or something when the crane is in motion. Adhering to the designated 2 feet clearance maximizes safety and operational efficiency in lifting tasks and other crane operations.
