What kind of loads requires special rigging considerations in sling loading?

Unbalanced loads require special rigging considerations in sling loading because their weight distribution is not equal on all sides. This uneven weight can lead to instability during flight, affecting the load's balance and increasing the risk of swinging or tipping while in transit. Proper rigging techniques and equipment are essential to stabilize these loads, ensuring they remain level and secure during movement.

In contrast, while single items and liquid loads can present challenges, they do not necessarily require the same level of specific rigging adjustments as unbalanced loads. For instance, a single item might be rigged using standard techniques if it is symmetrical, whereas liquid loads can be managed with specific containers designed to minimize movement. However, unbalanced loads inherently demand extra attention to ensure safety and effectiveness throughout the lift.
