HHH Mechanical & Electrical A pioneer in hydraulic transmission systems

—— Visiting HHH Cooperation MACH. ELEC.CO., LTD. Chairman Zhang Shu

How did you become a hydraulics expert, and why did you choose complete system integration as your core business when founding HHH Mechatronics?

Zhang Shu: 1979 In that year, I was admitted to Nanjing University of Aeronautics and Astronautics, where I majored in Automatic Control for Aero-Engines. This field primarily focuses on studying control systems, with a broad scope that encompasses areas like dynamics, fluid mechanics, thermodynamics, electrical control, computer science, and more. Hydraulic transmission systems, of course, are an integral part of these control systems. What resonated most deeply with me during my studies was the realization that control systems are "alive"—every component within the system must be meticulously tuned to its optimal parameters, ensuring that the final integration meets—and even exceeds—the system’s performance requirements. Aerospace technology inherently demands higher standards than civilian applications; back then, we were already delving into advanced topics such as electro-hydraulic automatic control, thermal management of hydraulic systems, and optimizing system volumetric efficiency.
    After graduation, I was assigned to the Guiyang Aviation Hydraulic Components Factory, which is now part of AVIC Liyuan Hydraulic Co., Ltd. (hereafter referred to as Liyuan Hydraulic), where I worked on designing hydraulic product testing systems. Thanks to the introduction of advanced foreign technologies, Liyuan Hydraulic has become a leading domestic manufacturer of high-pressure piston hydraulic pumps with significant industry strength. / The motor manufacturing company has nurtured a large pool of hydraulic professionals for China's hydraulic industry, and these talents are now strategically positioned across the country in hydraulic and related fields.
    Liyuan Hydraulics was the first employer that helped me transition from student life into the workforce, and it played a crucial role in my personal and professional growth. During my years at Liyuan Hydraulics, the company was experiencing a period of rapid expansion, and I was fortunate enough to gain exposure to cutting-edge technologies used in the defense industry—as well as to the critical heart components of hydraulic systems. —— Hydraulic pump. Liyuan Hydraulics is like a window—through it, I’ve been able to see the wider, more expansive world beyond.
    After working at Liyuan Hydraulics for a few years, I was transferred to the Sichuan Aviation Gas Turbine Research Institute (now the China Aviation Engine Corporation Sichuan Gas Turbine Research Institute), which happened to coincide with the institute’s exceptionally prosperous period. To address challenges in aviation engines, the country launched a series of international cooperation projects, and thanks to my role, I had the opportunity to contribute to several key collaborative initiatives. It was during this time that I developed a keen sensitivity to policy-related information and honed my ability to analyze complex situational dynamics.
    1989 Years later, many of the institute's international collaboration projects could no longer continue. 1994 This year, I decided to make the leap from the aviation industry into the business world. After leaving my previous role, I joined an alumni company to help expand their international operations. It was during this work that I met someone from the U.S. FEC The company, by a happy coincidence, 1998 This past year, the American company proposed collaborating with an alumni firm to establish a China-U.S. joint venture, aimed at helping the American company expand its hydraulic components business into the Chinese market. As part of this partnership, they offered me the opportunity to serve as the general manager of the new company. Several years later, due to unforeseen circumstances, the alumni partner transferred their Chinese stake in the joint venture to HHH Electromechanical, a company I had founded. Consequently, HHH Electromechanical became the controlling shareholder of the joint venture, giving rise to the newly formed HHH Hydraulic Co., Ltd. (hereinafter referred to as HHH Hydraulic).
    2001 , HHH Cooperation MACH. ELEC.CO., LTD. was established against the backdrop of China’s booming equipment manufacturing industry. Our core business focuses on the comprehensive system integration of electro-hydraulic transmission and control solutions. Positioning ourselves as a system integrator was something I determined by aligning my professional expertise with national policies and the evolving global and domestic landscape.
    The 15th National Congress of the Communist Party of China laid out a comprehensive plan for the century-spanning development of socialism with Chinese characteristics, sparking a second wave of reform and opening-up across the country. Thanks to this momentum, China’s infrastructure projects—including railways, highways, airports, and construction—experienced unprecedented growth, driving the rapid advancement of China’s equipment manufacturing sector. By integrating cutting-edge foreign technologies and products from the aviation industry into civilian applications, we can address the critical demand within the electromechanical industry for advanced electro-hydraulic power transmission and control technologies. Particularly in sectors like construction machinery, petroleum equipment, coal mining machinery, and specialized vehicles, hydraulic transmission and control systems are indispensable components. To ensure these systems deliver optimal performance and reliability, high-quality individual parts must be seamlessly integrated into cohesive systems—much like how traditional Chinese medicine emphasizes holistic, interconnected approaches to health and wellness. Only through such a coordinated, systems-oriented mindset can we effectively meet the complex demands of whole-machine transmission and control.
    To live up to the mission of our era and embrace its great responsibilities, HHH Electromechanical clearly defined—right from its inception— “ Focus on high-end equipment, advance its transmission systems, and infuse intelligence into the machinery—empowering China's high-end manufacturing industry. ” The company's business philosophy.

In its early days, which application area was HHH Mechatronics primarily focused on? How did the company earn the trust of international companies and secure product distribution rights? And what brands does it currently represent, along with the strategic partnerships it has established?

Zhang Shu: Being from a technical background, I often refer to the "Hydraulic Transmission Design Manual," which outlines the application areas of hydraulic systems. I noticed that one particular sector—construction machinery—relies heavily on hydraulic systems. At the time, I learned through an alumnus from XCMG Group that the company has been struggling to fully understand and optimize imported foreign hydraulic systems due to a shortage of specialized hydraulic talent. As a result, XCMG is actively recruiting graduates in this field from leading universities. After gathering insights from various sources, I concluded that construction machinery companies will continue to rely heavily on hydraulic systems, making the hydraulic system integration business incredibly promising.
    We noticed that the schematics and related documentation for these imported construction machinery hydraulic systems did not specify the manufacturers of the individual hydraulic components. Drawing on my years of experience collaborating with U.S. companies—and with their invaluable support—we managed to uncover some leads about the manufacturers. As a result, we proactively reached out to these hydraulic component makers, approaching their local branches or offices in China to discuss potential agency partnerships. Through technical discussions, they were thoroughly impressed by our professionalism, as well as our strong operational capabilities, keen market insights, and proven ability to tap into new opportunities. Even though we had no prior market achievements at the time, these multinational corporations still entrusted us with the agency rights for their hydraulic products. This marked HHH Machinery & Electronics as the very first agent of these companies in China.
    HHH Mechatronics was the first to secure the U.S. contract. Sauer (Later captured by Denmark) Danfoss Product agency rights through acquisition. Sauer Starting out by manufacturing aviation hydraulic pumps, the company later expanded into producing civilian hydraulic pumps—its business development closely mirrors that of Liyuan Hydraulics.
    20 Over the years, HHH Electromechanical has been dedicated to serving construction machinery and agriculture. / We provide power transmission systems, intelligent electro-hydraulic transmission and control complete sets for industries such as forestry machinery, petroleum equipment, coal mining machinery, metallurgical machinery, marine and auxiliary equipment, as well as airport and firefighting special vehicles. Additionally, we offer related technical consulting, maintenance services, and comprehensive parts support. Today, we have established a fully integrated product structure chain for transmission systems, with each component in the system backed by a dedicated partner—currently collaborating closely with nearly 20 A multinational corporation forms strategic partnerships, including Denmark. Danfoss Denmark Bukh Finland Sampo Finland Dynaset Italy Safim , Norway Siderpower Sweden MD , United States Dana , Germany Voss , Germany Class , United Kingdom Webtec Etc.
