As core equipment in China's "infrastructure powerhouse," the development level of excavators directly reflects the hard power of China's equipment manufacturing industry. Today, Chinese excavators firmly hold the top spot in both global sales and exports, with exports increasing by 26.3% year-on-year in 2025 and a global market share exceeding 75%. However, the pain point of "strong overall machine capabilities but weak core components" has long been a thorn in the side. Engines, as the "heart" of excavators, were long monopolized by Japanese brands, not only devouring most of the companies' profits but also exposing the supply chain to external risks.
The construction machinery supply chain is long, and the independent control of core components is the "ballast" for the security of the supply chain. The long-term monopoly of Japanese engines once put China's excavator industry in a passive situation where "a single change affects the whole system." In the early years, Chinese excavator manufacturers not only had to purchase Japanese engines at high prices but also faced difficulties in freely adapting them to the overall machine design due to technology licensing restrictions. They also faced multiple risks such as exchange rate fluctuations, import tariffs, and supply chain disruptions. This predicament of "lifeline in the hands of others" made the self-sufficiency of core components an inevitable choice for the industry's survival and development. China's leading core component manufacturers have proactively shouldered strategic responsibility, relentlessly overcoming critical bottlenecks through a decade of dedicated effort. Today, even amidst external supply chain fluctuations, Chinese excavators can maintain stable production thanks to domestically developed core components, significantly enhancing the resilience of the industrial chain and solidifying the safety net for China's construction machinery industry.
The self-sufficiency of China's core components is not simply about "import substitution," but rather about technological innovation leading the industry to a qualitative leap, reshaping the industrial development landscape. In terms of technological breakthroughs, Chinese engines have precisely addressed the weaknesses of Japanese counterparts, achieving superior performance in several areas: through combustion chamber structure optimization and intelligent power matching technology, fuel consumption is lower than Japanese competitors; breakthroughs in micron-level precision manufacturing processes have resulted in service life exceeding industry standards; product reliability has improved, overhaul cycles have been extended, and failure rates have been significantly reduced.
This innovative commitment is further reflected in its impact on the industry ecosystem. Chinese core component manufacturers, using technology export as a link, are driving the iterative upgrading of upstream and downstream industries, propelling the entire industry towards digitalization and intelligent transformation, and gradually breaking the technological dominance of Japanese brands.
In the global construction machinery market competition, the power to influence core technologies directly determines an industry's position. Previously, while Chinese excavators seized overseas markets thanks to their cost-effectiveness, the use of Japanese engines significantly squeezed profits and created technological barriers and import restrictions in the high-end market, making it difficult to compete with international giants. Breakthroughs in the self-sufficiency of core components have injected core confidence into the global competitiveness of Chinese excavators and shouldered the responsibility of enhancing the voice of China's construction machinery industry.
Self-developed core components have enabled Chinese excavators to achieve a leap "from exporting complete machines to exporting technology." On the one hand, Chinese engines are cheaper than their Japanese counterparts, and combined with the cost advantages of a self-developed supporting system, Chinese excavators have achieved high cost-effectiveness competitiveness in overseas markets, extending their export reach from developing countries to high-end markets in Europe and America. On the other hand, the reliability of Chinese core components has been verified under extreme working conditions, with a stable overhaul cycle of 20,000 hours, roughly on par with mainstream Japanese models. In large-scale mining projects worldwide, excavators equipped with Chinese engines have operated for over 24,000 hours without major malfunctions, winning international market recognition with their strength.
More importantly, self-sufficiency has given Chinese construction machinery the initiative in global competition. Chinese companies can independently conduct customized R&D of core components based on overseas market demands, significantly reducing the technological limitations imposed by Japanese companies and adapting to the emission standards and construction conditions of different countries. Simultaneously, supported by core technologies, they can participate in the formulation of global construction machinery technical standards, gradually breaking the standard monopoly of Japanese and European/American brands, and allowing the technological concept of "Made in China" to profoundly influence the global industrial landscape.
