the center of gravity is extremely important for rigging operations because it affects the stability and balance of the load. If a load is not properly balanced, it can tip over or shift during rigging operations, which can be dangerous for workers as it may lead to accidents and cause damage to the surrounding equipment. So what is center of gravity exactly? The Center of Gravity, or CG, is the point at which the entire weight of an object may be considered as concentrated, so when we do calculations, we assume that all the weight is at this point. The example presented on this page to illustrate this concept, is a water bucket. the center of gravity is illustrated by a black and white checkerboard sphere and we can observe that it is below the lift points of the bucket, shown with blue arrows pointing upwards. When a bucket is filled with water, the weight of the water shifts the center of gravity lower. If the bucket is not held at its center of gravity, it will become unbalanced and spill water. To avoid this, one should hold the bucket by its handle and keep it level, so that the center of gravity stays directly below the point of support.

In this water bucket example, the center of gravity is illustrated by a black and white checkerboard sphere and it is below the lift points of the bucket.
