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.
ISO 4301-1:2016 addresses classification using working cycles, load spectrum and average displacements. ISO 12480-1:2024 addresses safe systems of work including planning, selection, operation, maintenance and competent personnel. ISO 9927-1 and ISO 9927-5 provide inspection frameworks. Applicable standards must be defined in the project specification according to crane type, destination and contract requirements.
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.
