Lechuan Motor: Turning China's Intelligent Manufacturing Future in the Hydraulic Kingdom

In April in Qingdao, the sea breeze carries the vigorous spring atmosphere, blowing through the high-tech industrial development zone by the Jiaozhou Bay. In a group of modern silver gray factory buildings, the large red calligraphy characters of "Qingdao Lechuan Hydraulic Co., Ltd." are thick and powerful, particularly eye-catching. Entering this enterprise known for its "motors", one is greeted by the rhythm of mechanical processing and the breath of precision manufacturing - here, the rotation of each hydraulic motor connects the resolute steps of China's construction machinery towards high-end.

The industry 'little giant' moving from Qingdao to the world

In the company exhibition hall, a side of honor tells the market legend of Focus on Kechuan: National Specialized and Innovative Little Giant, Global Engineering Machinery Industry Conference Top 50 Parts Application, China's Top 100 Engineering Machinery Parts, Shandong Province Gazelle Enterprise, Shandong Province's First (Set) Technical Equipment and Key Core Parts Project, Shandong Province High end Brand Cultivation Enterprise, Shandong Province High end Equipment Leading Enterprise, Shandong Province Science and Technology Little Giant, Shandong Province Top 100 Innovation Potential Enterprises... These highly valuable honorary titles outline the leading position of this enterprise in the field of hydraulic drive. Since its establishment in 2006, Lechuan has been deeply involved in six major industries including construction machinery, agricultural machinery, and tunnel engineering, starting from walking motors. Its products cover more than 30 countries and regions, and it has become a core supporting supplier for leading domestic enterprises such as XCMG Group and Yuchai Heavy Industry.

The core technology is hard power

Hydraulic products have become a key transmission mode for modern industrial equipment due to their high torque, wide speed range, and fast response. Lechuan continues to make efforts in the integration of high-end hydraulic component systems in the fields of hydraulic systems and engineering machinery, and its product performance and quality have reached the world-class level in the hydraulic field. LTM07VBC and other digital series walking devices integrate intelligent control modules, which can achieve precise speed regulation; The LSMN10BA-10C hydraulic rotary device is like a precision artwork, supporting the excavator's 360 degree flexible rotation.

The market position of Lechuan is also reflected in the construction of the industry ecosystem. Lechuan is a member unit of the National Ministry of Industry and Information Technology's high-end hydraulic parts and hydraulic system industrialization collaborative work platform, and the vice president of Shandong Equipment Manufacturing Industry Association and the president unit of the Hydraulic Branch. At the Executive Council of Shandong Equipment Manufacturing Industry Association in 2025, Chairman Wang Jinbo was elected as the rotating president. He interpreted the grand vision of Lechuan to "create a world-class hydraulic brand" and proposed the "full life cycle hydraulic system maintenance plan", providing the "Lechuan plan" for cost reduction and efficiency improvement in the industry.

The 'Chinese Core' of Hydraulic Technology

Intelligent production workshop, high-precision machining center operates rhythmically. According to the official website of Qizhizhi, Lichuan is a national intellectual property advantage enterprise, with provincial-level enterprise technology centers and industrial design centers. It leads or participates in the formulation of national and industry standards, and its technical team focuses on "low-carbon, digital, and integrated" research and development. It has a total of 107 patents, including 9 invention patents.

Traditional hydraulic motors have high energy consumption and loud noise, while closed type walking motors, through pressure adaptive technology, enable construction machinery to save more than 15% energy under extreme working conditions. This product, designed specifically for high-altitude tunnel construction, has withstood the test of -30 ℃ low temperature and high-altitude hypoxia in the construction of the Sichuan Tibet Railway, breaking the long-term technological monopoly of Japanese companies. The new LP3VL80/95 hydraulic pump adopts a slanted disc axial variable design, which reduces the volume by 20% compared to similar products, but can output stronger power, becoming the preferred "heart" of new energy engineering machinery.

With the growth of global infrastructure investment and the increasing demand for high-end equipment, closed type walking motors are becoming increasingly popular in the market

At the Bauma 2025 exhibition in Germany, global construction machinery giants gathered, and Lechuan Hydraulic showcased 10 products from five major series, including hydraulic walking devices, hydraulic rotary devices, and hydraulic pumps. These products included LETM-HY3000 electric drive motors, LTM09Z closed motors, LTM08W winch motors, LSMN10BA-10C rotary motors, and more. Many domestic and foreign merchants signed orders and visited the company on schedule, all of which were sold out, allowing global peers to see the charm of "Chinese hydraulics".

Outline a new picture of industrial upgrading

In the factory area of Lechuan, details of green manufacturing can be seen everywhere: the roof of the factory covered with photovoltaic panels provides power for production, the waste cutting fluid recycling system enables resource recycling, and the water-based paint intelligent spraying system greatly reduces carbon emissions... These scenes are vivid examples of the company's ISO three system certification (quality, environment, occupational health and safety), and environmental protection technology upgrades have driven related supporting enterprises to achieve green transformation.

Lechuan's "chain innovation" model has driven the formation of a complete industrial chain around Qingdao, from casting blanks, hydraulic valve components to intelligent control systems. As a supporting enterprise, Hengsheng Casting has become a domestic enterprise that masters precision casting technology for hydraulic shells with the technical support of Lichuan. This "big leading small, strong supplementing chain" industrial synergy ecology is a typical path for the transformation and upgrading of China's manufacturing industry.

Intelligent manufacturing anchors the course of the future in the gears of the times

From a start-up company in Qingdao High tech Zone to a participant in the global hydraulic drive field, the story of Lechuan is a microcosm of China's manufacturing industry moving towards high-end, intelligent, and green development.

Standing in the new development pattern of "dual circulation", every technological breakthrough and motor rotation of Lichuan is injecting kinetic energy into China's equipment going global - in the gear meshing of precision machinery and the flow and circulation of hydraulic oil, it always resonates with the pulse of national industrial upgrading at the same frequency. Each motor here, embedded in the body of construction machinery, transmits power and a belief as China's manufacturing goes global: on the track of high-end equipment manufacturing, high-end equipment manufacturing enterprises represented by Lechuan are using innovation as the engine to rotate the gears of China's intelligent manufacturing era.
