Does the center of gravity always align directly under the crane hook when lifted?

The center of gravity of a load does not always align directly under the crane hook during lifting situations. When a load is lifted, various factors can influence its position, such as the way the load is rigged, its shape, distribution of mass, and the dynamics of movement.

If the load is not symmetrical or is improperly balanced, its center of gravity may shift, causing it to be offset from the hook. Furthermore, during lifting operations, the load can swing or rotate due to movement of the crane or external forces, further displacing the center of gravity away from the hook.

Understanding this concept is crucial for safety, as improper load handling can lead to tipping, swinging, or dropping of the load, which poses significant risks to both personnel and equipment. Recognizing that the load’s center of gravity is not always directly beneath the hook emphasizes the importance of proper rigging techniques and maintaining awareness of load dynamics throughout the lift.
