ISO 24620:2022 Crane Intelligent Ops & Maintenance Guide
ISO 24620:2022 — Intelligent Operation and Maintenance Specification for Cranes is a key technical standard in the crane industry. Developed by the International Organization for Standardization, it defines the technical requirements for intelligent operation and maintenance of cranes.
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 24620:2022 specifies the technical requirements and safety indicators for the intelligent operation and maintenance of cranes, covering all types of 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, forming a complete and coherent technical framework. The defined Technical Parameters and Safety factor requirements give design personnel a clear design basis, while also offering quantifiable acceptance criteria for third-party inspection bodies conducting Type Tests and Factory Acceptance Tests.
Core Technical Parameter Framework
Under ISO 24620:2022, the design and manufacturing of intelligent crane operation and maintenance systems must satisfy a rigorous set of technical parameters. These parameters are established on the basis of extensive test data and safety engineering principles, covering the entire process 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 24620:2022 sets out clear requirements for Factory Acceptance Test, Type Test, and periodic inspection of crane intelligent operation and maintenance systems. Factory Acceptance Test shall be carried out on each unit by the quality inspection department at the manufacturer's facility, and equipment that passes inspection 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 facility, or when major structural changes are introduced. The periodic inspection interval for equipment in service is determined by the work duty and operating environment, and generally shall not exceed 12 months. For heavy-duty cranes operating continuously at A7~A8 level, the inspection interval shall be shortened to 6 months as appropriate.

Safe Operation and Management Requirements
Under ISO 24620:2022, safe operation and routine management are central to compliance. The standard places strong emphasis on operator qualification and training, requiring that all operators complete specialized training and obtain the necessary certifications before assuming their duties. User units must establish a robust equipment file management system that documents the full lifecycle of the equipment—installation, usage, maintenance, and inspection. Any safety hazards identified must be addressed through the rectification procedure specified in the standard, ensuring the equipment remains safe and controllable at all times. The standard also imposes restrictive requirements on equipment use under extreme operating conditions.
FAQ
Q: What is the intelligent O&M model proposed by ISO 24620?
A: Condition-based maintenance (based on actual equipment status) replaces Periodic Maintenance (fixed intervals), significantly reducing O&M costs.
Q: What are the predictive capability requirements?
A: Early warning 30 days before a fault occurs, with a timeliness rate of ≥98% and a false alarm rate of ≤5%.
Q: How is maintenance optimized?
A: Maintenance intervals are dynamically adjusted based on vibration, temperature, and wear analysis, preventing both over-maintenance and under-maintenance.
Q: What are the remote support requirements?
A: Remote diagnostics review, online guidance, and a response time of ≤1 hour. Mobile-enabled real-time video support is also required.
