How is the load chart matched to a specific crane?

1. By operator name

2. By crane color

3. By serial number

4. By model type

The correct answer is: By serial number

The load chart is matched to a specific crane primarily by its serial number. Each crane is uniquely identified by its serial number, which ensures that the load chart reflects the actual specifications, capacities, and operational parameters of that particular crane. The load chart is essential for safe lifting operations, as it provides crucial information such as maximum load capacities at various boom lengths and angles, stability ratings, and operating conditions. Using the serial number to match a load chart helps prevent the use of incorrect data that could lead to unsafe operations. The load chart for a crane can vary even within the same model type due to differences in configurations, manufacturing tolerances, or modifications made to the equipment. Hence, relying on the serial number is the most reliable method to ensure that operators are using the correct load chart for the specific crane they are operating.
