Yuneng Chuangli Achieves New Breakthrough in Product Development —High Working Resistance, Large Mining Height Hydraulic Support Passes Type Test at National Testing Center in One Attempt

On December 4, 2025, exciting news arrived from Beijing. The ZY15000/29/63D hydraulic support, independently developed and manufactured by Shaanxi Yuneng Chuangli Intelligent Equipment Co., Ltd., a subsidiary of Shanghai Chuangli Group, successfully passed the type test conducted by the National Quality Supervision and Inspection Center for Coal Mine Support Equipment. Passing this test signifies that Yuneng Chuangli has ascended to a new level in both technological R&D and product quality within the coal mining equipment sector. This achievement lays a solid foundation for the company to further expand its market presence and enhance its core competitiveness, while also injecting powerful momentum into the Group's development path towards intelligent and integrated coal machinery.

As a key piece of equipment in the fully mechanized coal mining face, the performance of hydraulic supports is directly related to the safety and efficiency of coal mine production. The hydraulic support that passed this test boasts significant features including a high working resistance of 15,000 kN and a large mining height of 6.3 meters. It also incorporates automated control, enabling it to better adapt to complex geological conditions and high-intensity mining requirements. The high working resistance design ensures greater stability and reliability when the support faces roof pressure, effectively guaranteeing safe production on the working face. The large mining height increases the extraction efficiency of coal resources, creating greater economic benefits for coal mining enterprises.

During the product development process, the R&D team overcame numerous technical challenges and passed various manufacturability tests. Adhering strictly to process discipline during manufacturing, and through continuous optimization and repeated trials, they successfully developed this high-end hydraulic support product that meets national standards and coal mine requirements. The National Testing Center conducted comprehensive inspections and verification on this product, with the ZY15000/29/63D support passing the type test in one attempt. Its safety, reliability, and stability have reached domestically advanced levels.

The successful one-time passage of the ZY15000/29/63D hydraulic support type test marks a significant milestone in Yuneng Chuangli's development. It is not only high recognition of the company's technical strength and product quality but also a concrete manifestation of the company's active response to national coal mine safety production policies. Seizing this opportunity, the company will continue to make breakthroughs in product R&D, constantly enrich and improve its product portfolio, and simultaneously strengthen cooperation with coal mining enterprises. Together, they will promote the advancement and development of coal mining equipment technology, making greater contributions to ensuring national energy security and fostering local economic development。
