This guide is written from an overhead-crane perspective. Assessment should consider actual duty, load spectrum, cycles, site geometry, maintenance history and safety functions before brand or catalogue values.
A similar appearance or matching brand name is not sufficient. The existing component, system function and surrounding interfaces must be checked before replacement.
Decisions should not rely on a single symptom or catalogue value. Nameplate data, measurements, maintenance records, fault history and site observations should be reviewed together. Structural or safety-related changes require competent engineering assessment.
This content supports preliminary review. Equipment selection, structural calculations, compliance and commissioning decisions must be verified using site data and competent engineering.
