That said, if this is for actual work, please buy the official guide from the author. My post is just for study/reference.

For lifting and rigging engineers, accurate calculations are non-negotiable. Whether you're determining sling tensions, calculating center of gravity, or designing a custom lifting beam, the difference between a safe lift and a catastrophic failure often comes down to the math.

Verification of lift beams, calculation of sag and tension in suspended lines, assessment of wind forces, design of crane matting arrangements, and determining crushing forces in wrapped basket hitches.

The ground beneath the crane must withstand the massive forces exerted during a lift. Mobile cranes transfer their entire weight plus the load weight through the outrigger pads. Estimating Max Outrigger Load

Rigging engineering is the science of moving heavy loads safely and efficiently. In complex industrial environments, professional rigging requires more than just high-quality hardware; it demands precise calculations to prevent catastrophic failure. This guide provides an overview of essential formulas and principles for lift planning, with references to authoritative resources for your documentation. 1. Determining Load Weight and Center of Gravity

: The first step is determining the weight by multiplying the material volume by its density. Formula : The ground beneath the crane must withstand the

While a single, perfect "rigging engineering calculations PDF" is rarely free legally, you can assemble an excellent toolkit from OSHA, universities, and manufacturers. For specialized work (e.g., offshore, heavy haul), invest in the official standards. For learning and basic lifts, the free resources above will serve you well.

Sometimes, the best resource is the one you can carry with you on the job site.

To find the required breaking strength for a single-leg sling, you use the Factor of Safety (FoS). Required Breaking Load = Weight × Factor of Safety For learning and basic lifts

Verification that shackles and links match or exceed the worst-case sling tensions.

Heavy mobile cranes exert immense pressure on the ground. Engineers must calculate the required matting area to distribute the weight safely.
