Sling Load Calculation: Ensuring Safety in Aerial Lifting Operations

Why is it recommended to calculate sling load for a two leg bridle hitch instead of a four leg bridle hitch?

Options:

A. Two leg bridle hitch provides more stability

B. Two leg bridle hitch allows for easier calculations

C. Two leg bridle hitch mitigates the risk of uneven load distribution

Answer:

Final answer: C. Two leg bridle hitch mitigates the risk of uneven load distribution

When estimating the sling load for a four leg bridle hitch, it is generally recommended to calculate for a two leg bridle hitch. This is due to the potential risk of uneven load distribution among the four legs of the sling. In aerial lifting operations, the weight of the load may not be evenly distributed across all four legs of the bridle hitch. Factors such as displacement or the object's center of gravity can cause two legs to end up carrying most of the load.

By calculating for a two leg bridle hitch instead, operators provide a safety margin in the calculations. This approach helps to prevent overloading and potential accidents that could result from relying on calculations based on all four legs carrying an equal portion of the load. Ensuring that the load is evenly distributed among two legs reduces the risk of imbalanced loads and enhances the overall safety of the lifting operation.
