Here are a few options for a post, depending on where you intend to post it (e.g., a professional blog, a social media update, or a resource page).
The download covers the seven calculations every rigging engineer and lift director needs, with worked examples:
| Calculation | Why It Matters | |-------------|----------------| | Sling tension (vertical & choker) | A 45° choke angle doubles the tension—most failures start here. | | D/d ratio (diameter of bend / rope diameter) | Bend a 1″ rope around a 4″ pin and you’ve lost 50% of its strength. | | Center of gravity (3D) | A 1% CG error on a 50‑ton load = 1,000 lbs of unexpected tilt. | | Cribbing & crush pressure | Soft ground under a steel outrigger pad is a hydraulic press in slow motion. | | Sling angle factor | 60°? 1.15× load. 30°? 2× load. That’s not a margin—it’s a multiplier of danger. | | Hook load with spreader beams | Most people over‑design beams and under‑design the top shackle. | | Wind loading on suspended loads | At 30 mph wind, a large tank becomes a sail—lifting capacity can drop 40%. |
Each formula is shown without academic clutter — just engineering logic, a real‑world example (from lifting heat exchangers to steel trusses), and a practical safety factor recommendation.
A concise primer on key rigging engineering calculations, useful formulas, typical applications, and safe‑practice considerations for lifting and rigging operations. This is an overview for study and planning—not a substitute for site‑specific engineering, manufacturer data, or formal certification.
