ISO 24618:2022 Crane Digital Twin Technical Specification Explained
ISO 24618:2022 — Crane Digital Twin Technical Specification is a key technical standard in the crane industry, developed by the International Organization for Standardization to govern digital twin applications for lifting appliances.
The standard provides a unified technical basis for design personnel, inspection bodies, and end users. Kelude strictly follows its technical requirements throughout product development and manufacturing.
Scope and Application of the Standard
ISO 24618:2022 — Crane Digital Twin Technical Specification defines the technical requirements and safety indicators for digital twin applications in cranes, covering all lifting appliances with a Rated Lifting Capacity above 0.5 t. The standard applies not only to the design and manufacturing of new equipment but also provides clear technical guidance for the inspection, maintenance, and modification of cranes already in service. As a key component of the crane standard system, it aligns with the EN 13001 Crane Safety Standard series and ISO 4309 Wire Rope Inspection Standard, together forming a complete framework of technical specifications. The clearly defined technical parameters and Safety factor requirements give design personnel a solid design basis, while also providing third-party inspection bodies with quantifiable acceptance criteria for Type Test and Factory Acceptance Test procedures.
Core Technical Parameters Framework
Under ISO 24618:2022, the design and manufacturing of crane digital twin systems must satisfy a stringent set of technical parameter requirements. These parameters are established on the basis of extensive test data and safety engineering theory, covering the full spectrum from material selection to structural design. The Safety factor ranges specified in the standard take full account of fatigue life and limit load conditions under demanding operating environments. In engineering practice, design personnel must translate the standard's requirements into concrete design parameters, ensuring that the load capacity of every component meets the required safety requirements.

Inspection Requirements and Intervals
ISO 24618:2022 sets out clear requirements for Factory Acceptance Test, Type Test, and periodic inspection of cranes enabled with digital twin technology. Factory Acceptance Test must be carried out on each individual unit by the quality inspection department at the manufacturer's facility, and each certified unit shall be accompanied by a detailed inspection report and a Certificate of Conformity. Type Test is required when a new product enters initial production, when manufacturing is transferred to another plant, or when significant structural changes are introduced. For cranes already in service, the periodic inspection interval is determined by the work duty and operating environment, generally not exceeding 12 months. For heavy-duty cranes operating continuously at A7~A8 duty levels, the inspection interval should be shortened to 6 months as appropriate.

Safe Operation and Management Requirements
Under ISO 24618:2022, safe operation and routine management play a critical role in day-to-day crane operations. The standard places strong emphasis on operator qualification and training, requiring that all operators complete specialized training and obtain the necessary certifications before being allowed to operate equipment. User units are required to establish a comprehensive equipment file management system that documents the full lifecycle of the equipment, including installation, usage, maintenance, and inspection. Any safety hazards identified must be addressed through the rectification procedure specified in the standard, ensuring that equipment remains in a safe and controllable condition at all times. Additionally, the standard imposes restrictive requirements on equipment usage under extreme operating conditions.
Frequently Asked Questions
