Why is verifying the center of gravity important during lifting?

• A. To maximize speed.
• B. To reduce rope wear.
• C. To ensure stability of lift and prevent tipping or unbalanced loads.
• D. To comply with color codes.

Answer: (C)

Center of gravity tells you where the overall weight of the load effectively acts. In a crane lift, keeping the load’s CG within the crane’s stability limits is essential to avoid tipping or uncontrolled movement. The crane’s capacity is based on a specific CG location for the given radius and boom configuration; if rigging or the load shifts the CG outside that zone, the lifting forces create a tipping moment and can cause the crane to lose balance, tip, or suffer dangerous sway. Verifying the CG during lifting means checking the rigging arrangement, attachments, and load shape to determine the actual CG and ensuring it stays inside the safe region of the load chart for the current setup. This is why it’s essential: it directly governs stability and safe control of the lift. Other options aren’t about balance or stability—speed, rope wear, or color codes don’t address the lifting stability that CG verification ensures.
