Weight distribution at the attachment points is determined by measuring the distance from which point?

• A. The Center of Gravity
• B. The Load Center
• C. The Attachment Point
• D. The Sling Length

Answer: (A)

Where the load’s weight acts determines how it will be shared among the attachment points. That point is the center of gravity. In a lift with multiple slings, the tensions in each sling adjust so the vector sum of the sling tensions equals the total weight and the moments balance around the center of gravity. So knowing how far and in what direction the center of gravity sits relative to the attachment geometry tells you how the weight distributes across the attachments. Sling length or simply the distance to an attachment don’t set the distribution by themselves; they influence the angles and thus the exact tensions, but the center of gravity is the primary factor.
