en.Wedoany.com Reported - China's Zoomlion continues to advance in the field of construction machinery standardization, committed to shifting from product export to standard export and technology export. By leading the development of multiple international standards, the company promotes the global implementation of Chinese technology and masters the right to set international rules.
In 2012, the Secretariat of the International Organization for Standardization Technical Committee on Cranes (ISO/TC96) was established at Zoomlion, marking the first and only international standardization secretariat in China's construction machinery industry. Leveraging this platform, Zoomlion leads the work of the Subcommittee for Tower Cranes (ISO/TC96/SC6), with over 10 internationally registered experts deeply involved in multiple related international standards, including tower cranes, remote data exchange, and safety coordination.
In recent years, Zoomlion has achieved key progress in the field of international standards for tower cranes. In August 2024, the company led the revision and publication of ISO 12480-1, Cranes — Safe use — Part 1: General, which provides detailed provisions on crane maintenance, condition inspection and monitoring, tandem lifting, and the impact of new technologies on safe use requirements.
In April 2026, the revision of ISO 4302, Cranes — Wind load assessment, led by Zoomlion, completed the Draft International Standard (DIS) voting stage and received unanimous support from the committee. This standard incorporates Chinese storm map data for the first time, enhancing the applicability of the international standard within China and becoming an authoritative basis for global tower crane wind load design.
Furthermore, three international standards led by Zoomlion—ISO/TR 25201, Cranes — Effects of surrounding building groups on wind loads; ISO 7296-1, Cranes — Graphical symbols — Part 1: General; and ISO 12480-3, Cranes — Safe use — Part 3: Tower cranes—have formed mature draft standards after multiple rounds of working group discussions and have been successfully approved as new work items.
Zoomlion possesses 70 years of technical expertise in tower cranes. In 1956, its predecessor, the Changsha Construction Machinery Research Institute, developed China's first tower crane with independent intellectual property rights, the QTZ160. Focusing on complex overseas construction scenarios, the company leverages its accumulated overseas project experience to conduct specialized technical research targeting climatic conditions, construction scenarios, compliance systems, and environmental requirements across global regions. It applies core technologies, working conditions, and experimental data to international standard research, driving the development of global tower crane technology.
Relying on its accumulated expertise in tower crane design and R&D, structural safety, intelligent monitoring, and full lifecycle operation and maintenance, Zoomlion has completed the progression from product output to technology output, and from equipment export to standard export. It continues to deepen its involvement in international standardization development, propelling China's tower crane industry to take the initiative in global competition.
