Complete Guide to Rigging Engineering Calculations: Master the Math Behind Safe Heavy Lifts
Miscalculating the CoG leads to tilting loads, unequal sling loading, and potential crane tipping. 3. D/d Ratios and Rated Capacity Reductions
This collection is a gold mine for related calculations. It includes spreadsheets for: It includes spreadsheets for: Adjusting the Rated Lifting
Adjusting the Rated Lifting Capacity based on the type of hitch used (vertical, choker, or basket).
While PDFs are great for learning formulas, apps and online calculators offer speed and accuracy: Regulatory Standards and Safety Factors Including the dry
Before downloading any resource, ensure it covers these core areas:
Always check standard industry tables (such as ASME B30.9) to apply the correct efficiency reduction factor during your rigging engineering calculations. 6. Regulatory Standards and Safety Factors DeLong Rigging Solutions
Including the dry weight of the object, internal fluids, and the weight of the rigging hardware itself (blocks, shackles, spreader beams).
Older lifting handbooks might use obsolete safety factors that do not comply with modern regulatory requirements.
Real-world scenarios demonstrating how to calculate multi-crane lifts, drifting loads, and wind loading variables.
