What does CG stand for in lifting discussions?

• A. Crane Guide
• B. Center of Gravity
• C. Cable Gauge
• D. Chain Gauge

Answer: (B)

In lifting discussions, the key idea is identifying the balance point of the load—the point where its weight can be considered to act. This is the Center of Gravity. The CG is the location where the entire weight of the load can be thought of as concentrated, and it determines how the load will behave when lifted. Knowing the CG is crucial for rigging and crane operations because it guides where to attach slings to keep the load hanging level, how the load’s weight affects the crane’s capacity, and how the line of lift can influence balance and stability. If the CG shifts, the effective load on the crane changes and can cause tipping or side loading. The other terms listed don’t describe this balancing point; they refer to cable or chain sizes or aren’t standard terms for load balance. So Center of Gravity is the correct term.
