What may happen when operating a crane that is not level and swings to the low side?

• A. Radius decreases
• B. Load capacity increases
• C. Radius increases
• D. Stability improves

Answer: (C)

When operating a crane that is not level, if the crane swings to the low side, the radius of the load actually increases. This occurs because the crane's boom is extending out farther away from its center of rotation as it tips downwards. A larger radius means that the load is positioned further away from the crane's base, which can reduce stability and increase the risk of tipping over. It's important to understand that as the radius increases, the crane takes on a higher lifting moment, which can lead to potential overload and stability issues. Therefore, maintaining a level position is crucial for ensuring safe and effective crane operation.
