What tool is essential for identifying the angle of the boom during operation?

The boom angle indicator is critical for identifying the angle of the boom during crane operations. This tool provides real-time readings of the boom's angle, which is essential for safe lifting and material handling. Understanding the boom angle helps operators maintain proper load limits and stability during lifts, ensuring that they remain within the crane's operational capabilities.

Additionally, this indicator assists in preventing overload situations, facilitates optimal performance, and enhances overall safety by allowing the operator to make informed decisions while maneuvering the crane. Maintaining awareness of the boom's angle is crucial for effective and safe operation, particularly in complex lifting scenarios or when working with varied loads.

While other tools such as load cells, level gauges, and digital scales serve different purposes—such as measuring the load or assessing levelness—they do not provide the specific information about the boom's angle that is essential for safe crane operation.
