What is the purpose of the range diagram in crane operations?

The purpose of the range diagram in crane operations is to identify lifting capacities and clearances. This diagram is essential for understanding the specific capabilities of a crane in relation to the task at hand. It provides critical information such as the maximum load that can be lifted at various radii, the height limits for lifting, and the angular reach of the crane. This allows operators to ensure that the crane is not overloaded and that the lifting operations can be conducted safely, avoiding potential hazards associated with exceeding the crane's specifications.

Using the range diagram effectively helps to prevent accidents and inefficiencies on the job site by ensuring that all lifting operations are within the operational parameters defined for the equipment being used. This is crucial for maintaining safety for both operators and those working nearby. Proper use of the range diagram supports adherence to safety regulations and best practices in crane operations.
