Why is load monitoring important during crane operations?

Load monitoring is crucial during crane operations primarily to avoid exceeding the crane's rated capacity. Cranes are designed with specific weight limits, and operating beyond these limits can lead to catastrophic failures, such as tipping over, structural damage to the crane, or dropping the load.

By continuously monitoring the load during lifts, operators can ensure they are within safe limits, maintaining the stability and integrity of the crane. This practice is integral to safe operations and is a critical aspect of crane management to prevent accidents and ensure the well-being of personnel and property on the job site.

The other options relate to operational factors but do not directly address the primary safety concern that load monitoring mitigates. For example, determining the duration of the lift, managing hydraulic pressure, or keeping the operator alert may be important aspects of crane operations, but they do not address the risks associated with exceeding load capacities, which is the primary focus of load monitoring.
