Why is it important to know the center of gravity of a load?

Understanding the center of gravity (CG) of a load is crucial for ensuring stability during lifting operations. The center of gravity is the point at which the weight of the load is evenly distributed in all directions. Knowing this point helps riggers determine the best way to support the load, which minimizes the risk of tipping or swaying when it is lifted.

When the load is rigged correctly in accordance with its center of gravity, it enhances control and stability throughout the lift. This is particularly important because shifts in weight distribution can lead to dangerous scenarios where the load may tilt or fall, risking not only the safety of personnel but also the integrity of the load itself and the equipment used. Therefore, factoring in the CG is a fundamental component of safe rigging practices and effective lifting.

Other concepts, such as weight distribution on the crane or visual alignment, are important in their own right but are secondary to the critical role of the center of gravity in ensuring that the load remains stable throughout the lifting process.
