What is the primary purpose of the mast moment indicator?

• A. Measure fuel consumption
• B. Monitor rotor speed
• C. Indicate bending moments
• D. Assess gear wear

Answer: (C)

The primary purpose of the mast moment indicator is to indicate bending moments, which is crucial in assessing the structural integrity and performance of lifting systems, such as cranes and helicopters. Bending moments occur due to the loads applied to the mast, and monitoring these moments helps ensure the equipment operates within safe limits. By providing real-time data on the bending stress the mast is experiencing, operators can prevent overload situations that could lead to equipment failure or accidents.

In the context of lifting operations, this indicator plays a vital role in decision-making and enhances safety by allowing operators to respond proactively to changing load conditions. Understanding how much bending moment the mast can safely endure is essential for maintaining the longevity and reliability of the lifting system.
