About Crane & Rigging Load Calc
Crane and Rigging Load Calc is an offline calculator for an idealized sling-leg tension estimate.
Enter the total load, number of sling legs, angle measured from horizontal, and the rated vertical working load limit (WLL) for one leg. The model assumes equal load sharing and the same angle on every leg. It reports the load-angle factor, estimated tension per leg, estimated tension as a percentage of the entered single-leg WLL, and the sum of the estimated leg tensions.
Save calculation records on your device and export a PDF.
This tool does not calculate crane capacity or evaluate actual rigging geometry, hardware configuration, dynamic loading, or all lift conditions. It does not determine whether a lift is safe, approve a lift plan, or verify compliance with ASME, OSHA, or other standards. The warning below 30 degrees is an app-defined caution about increased modeled tension; it is not a statement that the angle is prohibited. Verify equipment markings and real conditions, and have the complete lift reviewed by qualified personnel.
