What type of device is the load boom indicator on a mobile crane?

The load boom indicator on a mobile crane is classified as a moment indicator. This device measures the moment, or load effect, exerted on the crane’s boom due to the weight being lifted. In crane operations, it is crucial to monitor the forces at play to prevent tipping or overload situations. By providing real-time feedback about the weight and load conditions, the moment indicator assists operators in making informed decisions about safety and operational limits, ensuring that the crane operates within its designed capacity.

This type of device directly relates to the stability and safety of crane operations, as maintaining a proper balance of the load and avoiding excessive moment is essential for safe lifting practices. Understanding the moment created by the load helps in preventing accidents and ensuring compliance with safety standards while using the crane.
