The rated capacity of a sling is only valid for a vertical lift.
The official OSHA website provides free, public-domain access to tables detailing rated capacities for alloy steel chain slings, wire rope slings, and synthetic web slings.
Crucial for preventing load tipping. It is calculated by summing the moments ( ) and dividing by the total weight: rigging engineering calculations pdf free download
F = m x g x h
When operating a crane, the load capacity decreases as the radius increases. Crane Capacity Check: 4. Stability and Tipping Calculations The rated capacity of a sling is only
Lifts do not occur in a static vacuum. Wind gusts, crane acceleration, and sudden braking create dynamic forces. Always apply a safety factor (typically 5:1 for standard rigging hardware) to accommodate these variables. D/d Ratios for Wire Rope Slings

Sites like ITI (Industrial Training International) provide free downloadable posters, infographics, and math workbooks via their resource libraries. To help you get the exact resource you need, let me know:
To help you perform these calculations quickly in the field, we have compiled a comprehensive reference manual. What is Inside the PDF Guide: Full mathematical derivations for multi-leg sling setups.
Ensuring the crane can handle the load at the required radius. 2. Essential Rigging Engineering Calculations
