ISO 9374-5:2021

Overview

ISO 9374-5:2021 - "Cranes - Information to be provided - Part 5: Overhead travelling cranes and portal bridge cranes" specifies the information that purchasers and manufacturers must exchange when enquiring about, ordering, tendering for, or supplying overhead travelling cranes and portal/portal-bridge cranes. The standard ensures clear, consistent technical data for selection, installation, testing and safe operation of these cranes.

Key topics and requirements

• Scope of information: Defines the details purchasers should supply with enquiries/orders (see Annex A format), and the technical information manufacturers must provide when tendering or delivering equipment.
• Manufacturer deliverables:
  • Technical information and test certificates to support installation, testing and use (referenced to ISO 7363).
  • Instruction manual covering routine servicing, inspection and maintenance.
  • Erection/installation information on request.
• Drawings & dimensions:
  • General arrangement drawings with dimensions demonstrating compliance with purchaser requirements and the clearance/restriction limits shown in Figures 1–6.
  • Detailed keys in the figures identify critical dimensions (span, outreach, hook lifting/lowering heights, rail positions, clearances).
• Load effects on runway:
  • Loads applied to runways should be calculated in accordance with ISO 8686-5 or by agreement between purchaser and manufacturer.
• Enquiry/order format:
  • Annex A provides a purchaser’s enquiry form including rated capacities, lifting ranges, speeds, site data (wharf elevation, mean water level), and bulk handling throughput coordinates where applicable.

Applications and users

Who uses ISO 9374-5:2021:

• Crane purchasers (terminals, factories, shipyards) preparing enquiries or orders.
• Crane manufacturers and suppliers preparing technical offers and delivery documentation.
• Engineering consultants and structural designers ensuring runway and building interfaces meet crane loads and clearances.
• Installation and maintenance teams relying on manufacturer-supplied manuals and test certificates.

Practical applications:

• Specifying overhead travelling cranes and portal/gantry cranes for industrial plants, ports and bulk-handling terminals.
• Ensuring accurate tendering, avoiding scope gaps, and verifying that crane geometry and capacities match site constraints.
• Coordinating crane interface dimensions with civil and structural design.
