To achieve load stability when lifting, attachment points should be placed above the center of gravity. This positioning helps balance the load in a manner that minimizes the risk of tipping or swinging during the lift. When the attachment points are above the center of gravity, the load's weight is more effectively balanced, providing greater control and stability as the load is moved.

When the attachment points are positioned correctly, they create a situation where the center of gravity is aligned with the lifting point, allowing for safer handling of the load. This is particularly important for irregularly shaped or unbalanced loads, as it aids in preventing hazardous situations during transportation.

In contrast, alternative positions, such as below the center of gravity or at the edges, can lead to instability and may compromise safety during the lift. Attaching at the base of the load can also create challenges in maintaining control, making it more difficult to manage and increasing the likelihood of accidents. Hence, securing the load with attachment points above the center of gravity is the preferred method in industry practices.
