Which rigging arrangement provides the most strength for lifting loads?

The basket rigging arrangement provides the most strength for lifting loads because it distributes the load evenly across both legs of the sling. In a basket configuration, the sling wraps under the load and connects back to the hook, effectively doubling the lifting capacity for that sling. This design minimizes stress concentration and stabilizes the load, allowing for safer and more efficient lifting operations. The configuration also reduces the risk of the sling slipping off the load, further enhancing safety during lifts. Because of these factors, the basket arrangement maximizes the use of the sling's strength, making it the preferred choice for heavy or awkward loads.
