ISO 4306-5:2005 PDF

Overview

ISO 4306-5:2005 - "Cranes - Vocabulary - Part 5: Bridge and gantry cranes" is an ISO vocabulary standard that defines the most commonly used terms and definitions specific to bridge and gantry cranes. Published in 2005 and prepared by ISO/TC 96 (Cranes), SC 9 (Bridge and gantry cranes), this bilingual (English/French) part of the ISO 4306 series standardizes terminology for components, configurations and operational features used across design, manufacture, installation and maintenance.

Key topics

This part focuses on clear, standardized definitions rather than prescriptive design rules. Key topics and example terms covered include:

• Crane types and configurations: single‑girder bridge, double‑girder bridge, multi‑girder bridge, cantilever gantry, polar crane.
• Specialised cranes: ship‑to‑shore gantry cranes, rubber‑tyred gantry (RTG) cranes, gantry with traversing jib.
• Components and assemblies: crab/trolley (cantilevered, slewing), end carriage, guide roller, wheel pitch, bridge cabin drive.
• Geometric and operational terms: bridge girder camber, built‑in camber, boom, boom latch, side pull.
• Cross‑references to related definitions in ISO 4306‑1 are provided where applicable.

Practical applications

ISO 4306-5:2005 is a reference vocabulary used by:

• Crane designers and manufacturers who need consistent terminology in drawings, specifications and technical documentation.
• Engineers and consultants specifying crane systems for industrial plants, ports, factories and warehouses.
• Procurement and contract teams preparing tender documents and acceptance criteria.
• Maintenance, inspection and safety professionals who rely on unambiguous terms in procedures and reports.
• Technical writers and trainers producing manuals, training materials and translated documents.

Using a common vocabulary reduces misinterpretation across international projects, supports regulatory compliance, and improves clarity in contracts, installation instructions and safety documentation.

Related standards

• ISO 4306‑1 (General) - provides the broader crane vocabulary and is cross‑referenced.
• Other parts of ISO 4306 cover mobile cranes and tower cranes (Parts 2 and 3).

By adopting ISO 4306-5:2005 terminology, organizations in the crane industry ensure consistent, internationally recognized language for bridge and gantry crane components, types and operational concepts-improving communication, safety and interoperability.
