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.

Reference comparison

Hardware Reference Check

Compare a calculated hardware demand with stored reference WLL rows. Use the comparison as a field aid; verify the exact hardware, configuration, and manufacturer data before use.

Verify the exact product

WLL depends on manufacturer, model, material, loading direction, side-loading limits, installation, and configuration. The exact tag/chart and current manufacturer instructions remain authoritative.
