Lift Plan & Centre of Gravity
An off-centre load does not share equally between lift points — the point nearer the centre of gravity carries more. Build the assembly CG from its parts, then check what each pick point actually takes. Sling angles are handled by the Sling Angle & WLL tool.

Enter where the two pick points sit along x. The CG from the table above decides how the load splits.

Rigging is life-safety work — follow ASME B30.9/B30.20 and your site lift plan, and use certified hardware. A helper, not a substitute for engineering judgment.
