When making a lift the center of gravity of the load should be_____________.

• A. Directly under the boom tip
• B. Directly over the carrier center
• C. To the side of the crane
• D. Above the operator's station

Answer: (A)

In a lift, the weight of the load should act straight downward through the crane’s line of pull to keep the lift stable. Placing the load’s center of gravity directly under the boom tip aligns the load’s weight with the hook, creating a vertical lift with no sideways force. This minimizes sway, reduces tipping risk, and helps you use the crane’s rated capacity safely. If the load’s CG is off to the side, above the operator, or away from the boom tip, a lateral moment is created that can destabilize the crane and make control harder. Keeping the load’s CG directly under the boom tip ensures a safe, controllable lift.
