The situation of the advanced development of the foundation of the construction machinery industry

By 2025, China's construction machinery industry will achieve breakthrough progress in the high-end construction of its foundation in multiple fields. The core aspects are reflected in the autonomy of key technologies, the research and development of basic and common technologies, and the collaborative optimization of the industrial chain. The specific progress is as follows:

️ ‌ I. breakthrough in the localization of core components ‌

Youdaoplaceholder0 Hydraulic and transmission systems ‌

Youdaoplaceholder0 Hydraulic components ‌ : Hengli Hydraulic has broken the foreign monopoly and successfully developed a 500kW multi-speed transmission, which is applied to heavy equipment such as mining motor graders, achieving large-scale application of high-end hydraulic components.

Youdaoplaceholder0 Transmission technology ‌ : Nanjing High Gear has launched high-end transmission solutions, covering fields such as wind power and mining machinery. Its global market share of wind power gearboxes has ranked first in the world for nine consecutive years, and it has obtained a total of 332 patents.

Youdaoplaceholder0 Power system upgrade ‌

Hangzhou Gear Group has released the third-generation high-speed integrated electric drive assembly (EH100/EH120), simplifying the power chain structure, enhancing energy efficiency, and promoting the implementation of "oil-to-electricity" technology.

Youdaoplaceholder0 II. Progress in the Research and Development of Basic Common Technologies ‌

Youdaoplaceholder0 Intelligent manufacturing and digitalization ‌

Industrial Internet platforms such as XCMG Han Yun and Sany Tree Root Internet deeply integrate Internet of Things and AI technologies to achieve full life cycle management of equipment and break down data silos.

Many enterprises have been selected as national-level intelligent manufacturing demonstration factories, the coverage rate of digital workshops has increased, and the average production efficiency has risen by 35%.

Youdaoplaceholder0 green manufacturing technology ‌

Sales of electric construction machinery have seen a significant increase: From January to April, the sales volume of electric loaders was 8,139 units, up 255% year-on-year. Electric forklifts account for 74.4%.

Breakthroughs have been made in the research and development of hydrogen energy and methanol power equipment. The Hyundai HW155H hydrogen-powered wheel excavator has been shortlisted for the BMW Innovation Award.

Iii. Modernization of the industrial chain ‌

Youdaoplaceholder0 high-end complete machine research and development achievements ‌

Large and super-large equipment has achieved independent control: XCMG's XCA4000 tire crane (with a transfer weight of 400 tons), super-large diameter shield machines, and tower cranes over 10,000 meters have participated in major domestic and international projects.

Lingong Heavy Machinery's RTE136 pure electric mining truck, Dynapac REDLINE paver and other high-end products have won international innovation awards.

Youdaoplaceholder0 industrial chain synergy strengthening ‌

The "14th Five-Year Development Outline for the Machinery Industry" promotes the industrial foundation reconstruction project and establishes a collaborative system covering "core components - materials - processes - standards".

The industry standard system is well established, promoting the efficient connection between technological research and development and industrialization
