This book, available through the ITI Bookstore, is specifically a "how-to" resource for a wide range of rigging engineering calculations. It explains principles and derives formulas with worked examples in both US customary and metric units. The 214-page volume covers how to:
Precise rigging engineering eliminates guesswork, ensuring that every component of the lifting system—from the crane hook to the smallest shackle—operates within its engineered safety factor. In modern practice, these manual calculations are often verified using Finite Element Analysis (FEA) software to account for dynamic loading and environmental variables like wind speed.
