Rigging Engineering Calculations Pdf Free Download Extra Quality _verified_ Jun 2026

Which apply to your region? (e.g., ASME, EN, OSHA)

A common rule of thumb is that at a 60° angle, the sling tension is roughly 1.15 times the share of the load. At a 30° angle, it's double the share of the load. The American National Standards Institute (ANSI) generally recommends against using sling angles smaller than 30°.

Identifying the load's center of gravity is paramount for a stable lift. Lifting a load outside its COG will cause it to shift, creating uneven stress on rigging components and causing dangerous instability. Which apply to your region

Where to Find Legitimate, Free, and Low-Cost Rigging Resources

Companies like , Lift-It , and Slingmax offer free technical PDFs with rigging calculators, load charts, and cut sheets. They want you to rig safely—it’s good for business. Where to Find Legitimate, Free, and Low-Cost Rigging

By mastering these equations, rigging engineers minimize structural risks, protect multi-million dollar assets, and maintain strict compliance with global safety standards like OSHA, ASME, and LEEA.

For asymmetrical loads, the center of gravity dictates how weight is distributed across the lifting points. Rigging engineers use moments to find the precise CG location: factor of safety

Use certified load cells or crane scale readouts during a test lift. Center of Gravity (CG)
