Field Calculation Aid — Verify Critical Results

Use LoadCalc at your own risk. Independently verify critical inputs, geometry, calculations, load paths, and equipment ratings before use. LoadCalc is not a substitute for qualified rigging knowledge, required engineering, current manufacturer data, applicable standards, or site procedures.

Equipment verification

Treat the calculated sling tension as the required load demand. Compare that demand directly with the exact manufacturer WLL for the sling, hitch, angle, and connecting hardware. Do not divide the demand by a design factor or infer capacity from breaking strength.
