Why should the crane operator monitor the load moment indicator when lifting tilt panels?

Monitoring the load moment indicator is crucial for crane operators when lifting tilt panels, particularly due to the unique dynamic forces involved in such operations. Tilt panels can generate significant dynamic forces as they are lifted, especially when the panel experiences suction or wind resistance. The load moment indicator provides real-time feedback on the load being lifted, helping the operator to ensure that the crane's lifting capacity is not exceeded.

When suction occurs, it can create additional forces that may not be immediately obvious. If the load moment indicator shows that these forces are near the crane's limits, the operator can adjust their approach to avoid tipping or destabilizing the crane. Therefore, the use of the load moment indicator is essential for maintaining safety and control during the lift, allowing the operator to respond proactively to any excessive dynamic forces that may arise due to the panel's position and the surrounding conditions.
