Choker hitches are a common rigging method used in lifting operations to secure loads effectively. The correct answer emphasizes that they can reduce the Safe Working Load (SWL) or Working Load Limit (WLL) based on the shape and characteristics of the load being lifted.

When a choker hitch is applied, the tension in the rigging can cause the rope or sling to tighten around the load. This tightening can limit the surface area that the sling makes contact with, especially if the load is irregularly shaped. As a result, this can reduce the effective lifting capacity because the sling may not distribute the weight of the load as evenly as it would with other types of hitches. Therefore, it's crucial to understand the shape of the load and how it interacts with the rigging to ensure that lifting operations remain safe and within the designated limits.

In contrast, while choker hitches may contribute to load stability in some scenarios, they are not specifically designed to increase stability, which can depend on various factors including load shape and weight distribution. They can make lifting easier in certain situations by providing a more secure grip on the load, but this is not a guarantee for every load configuration. Calculating SWL is always necessary, as the specifics
