Every lifting plan begins with fundamental physics. You must calculate the weight of the load, the center of gravity, and the tension applied to each piece of hardware. Load Weight Estimation

Modern rigging engineers use dynamic calculators. A good PDF will often accompany spreadsheets that automate:

Here are a few worked examples to illustrate the concepts:

Avoid horizontal sling angles below 45 degrees. Angles below 30 degrees are exceptionally hazardous. 2. Center of Gravity (CG) Determination For asymmetrical loads, calculate the distance ( ) from a reference point to distribute weight safely.

Contains compiled formulas and worked examples, which are highly useful for practical applications.

Rigging engineering is the backbone of heavy lifting, construction, and maritime operations. A single calculation error can lead to catastrophic equipment failure, financial loss, or fatal accidents. Mastering these calculations ensures every lift operates within strict safety margins.

The Hoisting and Rigging Fundamentals PDF is a comprehensive, free resource that includes calculation objectives and equipment limitations.

Visual guide for eye bolts, shoulder bolt load limits at angles, and quick-reference charts. Advanced Rigging Principles (OSHA)

For those interested in learning more about rigging engineering calculations, there are several free PDF resources available online. Some popular resources include:

Never rig at an angle horizontal to the load lower than 30 degrees , as the tension multiplies rapidly, potentially exceeding the sling’s Working Load Limit (WLL) . 3. Finding the Center of Gravity (CoG)
