How is a load's center of gravity determined?

Determining a load's center of gravity involves analyzing the shape and weight distribution of the load rather than simply weighing it or measuring other physical attributes. The center of gravity is the point where the entire weight of the load is effectively concentrated, and this point can significantly influence the stability and balance when lifting or rigging the load.

By understanding the shape and weight distribution, one can identify how the mass is distributed in three dimensions. This analysis is essential, especially for irregularly shaped loads, as it helps riggers anticipate how the load will behave when lifted, ensuring safety and efficiency during the lifting process. For example, if most of the weight is concentrated on one side, the center of gravity will shift accordingly, which can lead to imbalance if not properly accounted for during lifting.

Other factors such as weighing the load, measuring its height, or assessing the type of material may provide useful information, but they do not give a comprehensive understanding of how the load's weight is distributed in relation to its overall shape, which is critical for safely rigging and lifting the load.
