If a crane is set up out of level, what happens when it swings to the low side?

• A. Load capacity decreases
• B. Radius remains constant
• C. Radius increases
• D. Stability of the crane improves

Answer: (C)

When a crane is set up out of level and it swings to the low side, the radius actually increases. This is due to the geometry of the crane's configuration. When the boom is not level, as the crane swings to the low side, the effective radius from the center of the crane's rotation increases because the load is further away from the pivot point. This increase in radius means that the crane may experience an increased moment or leverage exerted on its base, which can lead to stability concerns. Specifically, if the radius increases while the load capacity remains compromised due to the crane being out of level, it can also heighten the risk of tipping. Therefore, understanding how the radius changes when a crane is set up improperly is crucial for ensuring safety and proper operation.
