Rigging Engineering Calculations Pdf Free Download High Quality Jun 2026

Essential for job-site use, these concise guides put critical data at your fingertips.

) of an outrigger pad based on the Ground Bearing Capacity (GBC) of the soil:

When slings are used at an angle, the tension in the slings increases dramatically. This is due to the addition of horizontal forces. The Sling Angle Factor (SAF)

Horizontal Angle | Tension Factor (Multiplier) ---------------------------------------------- 90° | 1.000 60° | 1.155 45° | 1.414 30° | 2.000 (Load doubles!) Critical Rigging Formulae

Avoid lifting with horizontal sling angles below 45 degrees; 60 degrees is the industry preferred minimum.

To find the exact point where a load balances between two rigging points:

The weight of the crane’s lower block and overhaul ball. Finding the Center of Gravity (CG)

If you are designing a or an engineering cheat sheet ? Whether you follow ASME (US) or EN (European) standards?

Do you need a or an educational textbook/manual ?

A PDF can be a great quick-reference tool on the job site, but it is no substitute for proper training and certified engineering software. Use these resources to learn the formulas, but always verify your calculations before the lift.
