In a basket hitch, what does the proper D/d ratio help ensure?

The correct choice emphasizes the importance of the D/d ratio in ensuring the safety of the lift operation during a basket hitch. The D/d ratio represents the diameter of the hook (or the load) divided by the diameter of the sling or lifting device. Maintaining an appropriate D/d ratio is crucial because an excessively high ratio can lead to increased risk of sling damage or failure due to undue stress on the fibers, while a low ratio can cause slippage or instability during lifting.

A properly calculated D/d ratio ensures that the load is evenly distributed across the sling, which helps in minimizing the potential for accidents caused by sling breakage or load shifts. It is essential to follow manufacturer's guidelines regarding the D/d ratios to maintain safe lifting practices. This focus on safety is necessary to protect workers and equipment involved in lifting operations, making it a vital consideration in any lifting scenario.
