Overview
ISO 9374-4:1989 - "Cranes - Information to be provided - Part 4: Jib cranes" specifies the information that a purchaser must supply when enquiring for or ordering a jib crane, and the information a manufacturer must give when tendering or supplying a jib crane. The standard ensures that the crane design, selection and installation match the intended service, site constraints and operating conditions. Annex A provides a purchaser’s format (checklist/template) for the required data.
Key topics and technical requirements
ISO 9374-4 focuses on practical specification data rather than design methods. Important technical topics include:
Applications and users
ISO 9374-4 is intended for:
- Purchasing departments drafting enquiries and orders for jib cranes.
- Crane manufacturers preparing tenders and technical offers.
- Engineers and installers who need consistent, complete site and crane data for safe installation and commissioning.
- Asset owners and maintenance planners specifying operational limits, environment-related protections and electrical requirements.
Using ISO 9374-4 reduces ambiguity in specifications, helps match crane selection to service conditions, and supports safe, compliant installation.
