If a crane is not set up level and the operator swings a load from the high side to the low side, what happens to the load radius?

• A. It decreases
• B. It remains the same
• C. It increases
• D. It fluctuates unpredictably

Answer: (C)

When a crane is not set up level and the operator swings a load from the high side to the low side, the load radius increases. This is primarily due to the geometry of the crane's setup. In a situation where the crane is positioned on an incline, swinging the load from a higher elevation to a lower elevation effectively extends the distance from the center of rotation of the crane to the load. As the load is swung from the high side, its path is longer, causing the boom to rotate and the radius from the center of the crane's rotation to the point where the load is hanging to increase. This can lead to potential stability issues, as an increased load radius puts more leverage on the crane, which can affect its overall balance and safety. Understanding the impact of crane setup on load radius is critical for safe operation and planning, as operators must account for changes in dynamics when the crane is not level.
