Prototype for engineering validation only. The governing limit must originate from the crane OEM Instructions-for-Use; the 10-min→3-s gust at height is a Eurocode-based estimate (EN 1991-1-4) and does not replace the crane anemometer or a forecast provider. Final authority on lifting rests with the crane operator.
Enter the lift data and run the assessment. Results, the governing wind limit, the calculation trace and all integrity checks will appear here and be written to the audit log.

Each entry binds the previous entry's hash, so any later edit, deletion or back-dating breaks the chain and is detectable on verification. Integrity flags catch physically implausible or out-of-bound inputs at the point of entry.
