在引领技术革新方面，中国牵头制定的臂架起重机等关键标准，为固定式起重机、桅杆起重机等多种机 型，优化装备全生命周期性能与可靠性提供了依据。在便利国际贸易方面，中国专家与各国专家一道完 成了ISO9374系列标准，规范了供需双方技术信息交换框架，降低了沟通成本与合同执行风险。（记者 孔德晨） 《人民日报海外版》（2026年02月06日 第 03 版） 责编：李芳、李雪钦 人民日报海外版北京2月5日电 记者5日从国家市场监督管理总局获悉，中国牵头的《起重机 工作级别 第4部分：臂架起重机》ISO国际标准近日发布。 市场监管总局有关负责人介绍，"十四五"时期，全球起重机领域共发布18项国际标准，其中9项由中国 牵头制定，为国际标准化发展贡献了中国力量。中国作为全球起重装备最重要的研发与制造基地，实现 了从产品"走出去"到技术"走出去"，再到标准"走出去"的跨越。作为ISO/TC96国际标准化组织起重机技 术委员会秘书国，中国积极协调来自德国、法国、韩国、俄罗斯等20多个国家的专家，高效推动国际标 准研制。 ...

Core Viewpoint - The standardization in transportation is driving cost reduction, quality improvement, efficiency enhancement in logistics, development of smart transportation, and green low-carbon transformation in the sector [1][8]. Group 1: Transportation Standardization - The Ministry of Transport's Standardization Management Committee has recommended a series of typical cases in transportation standardization, emphasizing its role as a technical support for economic activities and social development [1]. - Standardization plays a foundational and leading role in modernizing the national governance system and governance capabilities [1]. Group 2: Case Study - Guizhou Province - Guizhou Province has identified issues with low standards in early-built highways, leading to significant speed limit reductions and non-standard signage [1]. - The province aims to optimize speed limits on highways to improve traffic flow and travel experience, with a technical guideline set to be implemented from April 2024 [2]. Group 3: Speed Limit Optimization - The new speed limit guidelines categorize limits into four types: 80 km/h, 100 km/h, 110 km/h, and 120 km/h, with specific rules for tunnels and transitions between speed zones [2]. - By July 31, 2024, 8,857 kilometers of highways in Guizhou will have optimized speed limits, with 99.2% of the routes experiencing an increase in speed limits [3]. Group 4: Infrastructure Improvements - The optimization has led to a reduction of 1,278 abrupt speed reduction zones, maintaining a maximum speed difference of 20 km/h between adjacent segments [3]. - The adjustments have addressed common complaints regarding sudden speed drops, enhancing overall driver experience [3]. Group 5: Standardization in Port Operations - Dalian Port has undergone standardization improvements to enhance the efficiency and quality of sea-rail intermodal transport, addressing the "last mile" bottleneck [5]. - The average time for railway freight cars at the port has been reduced from 10.6 hours in 2023 to 9.6 hours in 2024, marking a significant improvement [5]. Group 6: Environmental Initiatives - Ningxia's transportation department has established local standards for the comprehensive utilization of industrial solid waste, achieving a significant reduction in carbon emissions and energy consumption through innovative materials in highway construction [5]. Group 7: International Development - The standardization efforts are also facilitating international transportation development, as seen in the Lahore Orange Line project in Pakistan, which boasts a train operation and punctuality rate exceeding 99.9% [8]. - The export of various types of cranes to countries involved in the Belt and Road Initiative reflects the growing influence of China's transportation standards abroad [8].
