The Limitations of Free PDFs
While a rigging engineering calculations pdf free download is an excellent resource for field engineers and experienced riggers, it cannot replace formal engineering judgment. Free documents often: Use simple statics: sum of vertical forces =
- Use simple statics: sum of vertical forces = W; moments = 0 to find reactions.
- For asymmetric loads, compute reaction forces at each support via moment balance about supports.
Key concepts
- Load types: dead load, live load, dynamic/load impact, wind, surge, eccentric load.
- Center of gravity (CG) and load distribution.
- Wire rope, chain, synthetic sling characteristics.
- Rated capacities: Working Load Limit (WLL), Safe Working Load (SWL), Minimum Breaking Strength (MBS).
- Factors of Safety (FoS) and design factors (common values: 5 for life-safety lifts, 3–5 depending on standards).
- Rigging hardware: shackles, hooks, spreader bars, beam clamps — inspect for rated markings.
- Sling angles and effect on tension (sling angle increases tension).
Several formulas and methods are used in rigging engineering calculations, including: Key concepts
