6. Basket Sling to Load Angle
The horizontal angle formed between the sling leg and the “top” of the load.

7. Illustrated right - Increased tension is magnified by any change from vertical to horizontal lifting. Increased tension is imposed on the sling leg(s) when the legs are used at angles less than 90°.

13. Center of Gravity
For best control, attach the slings above the CG. When this is not possible keep the CG contained with three or four sling legs or use basket or choker hitches with wraps. These measures may not guarantee load control. The user must be assured, based upon the specific application that selected methods are suitable and comply with all applicable standards and regulations.
