Close the Hooks – Lifting Mathematics for Advanced Field Professionals

Close The Hooks is a unique textbook that combines hands-on lifting experience with mathematical precision. The book is intended for professionals in the field who want to understand the forces, balance, and sling angles involved in lifting operations – not just through experience, but through calculation and logic.

The book is suitable for:

• Lifting operation planners
• Load riggers and lifting personnel
• Trainers and safety professionals
• Anyone seeking to develop their technical thinking in lifting operations

The book clearly presents, among other things:

• the basics of moment calculation in practical situations
• the effects of the center of gravity on lifting operations
• the calculation of sling angles
• and other mechanical principles related to lifting operations

The book does not require advanced studies in mathematics but does require a solid grasp of basic arithmetic and a willingness to apply that knowledge to real-life lifting scenarios.
