The modernization of global underground mining operations is highly dependent on auxiliary transportation and support handling equipment. As global mining companies delve into deeper subterranean levels, the challenges associated with structural roof support, wall maintenance, and high-pressure fluid conveyance increase exponentially. Handling shield supports, hydraulic props, and massive mechanical structural assemblies requires not only extreme mechanical power but also unparalleled sealing and hose integrity.
Across key mining hubs in North America, Australia, South Africa, and Northern Europe, heavy-duty material handling machinery must function reliably in abrasive environments contaminated by fine coal dust, quartz particles, moisture, and corrosive atmospheric gases. The failure of a single hydraulic cylinder seal or a high-pressure transmission line can cause catastrophic operational downtime, costing operators hundreds of thousands of dollars per hour. This risk has transformed how global EPCs and mining groups evaluate potential manufacturing partners and exporters.
Information Gain Insight: Modern mining operations prioritize "zero-leakage" hydraulic components. The integration of high-precision seals (using Austrian DMH technology) and high-pressure rubber hoses (produced on Italian imported lines) provides a robust defense against pressure loss and mechanical failure in heavy-duty longwall shield movers and support transporters.
Founded in 1996, Shaanxi Kelong New Materials Technology Co., Ltd. grew from the prestigious Xianyang Kelong Rubber Products Institute. Today, it stands as a leading technological innovation enterprise integrating R&D, production, sales, and on-site engineering services. Kelong concentrates on high-performance hydraulic seal sets, high-pressure rubber hoses, coal mine auxiliary transportation equipment (including frame-type handling vehicles), and customized technical repair programs.
Kelong's products are widely implemented in demanding industries worldwide, including coal mining, civil aviation, high-speed rail, heavy engineering machinery, and wind power generation. With deep domain expertise, the company is ranked among the top three in the Chinese domestic coal machine sealing industry. Kelong is also poised to place its high-pressure rubber hoses and frame-type handling vehicles in the national top three within the next two years. Currently, Kelong maintains an 8% market share in the Chinese domestic market.

Shaanxi Kelong New Materials Technology Co., Ltd. has prioritized advanced manufacturing infrastructure. The company’s total assets are currently valued at 600 million RMB, with a robust annual output of 300 million RMB. Over 40% of our 400+ employees are college graduates, and technical R&D personnel account for 17.5% of the total workforce.
To maintain our leadership position, Kelong allocates more than 7% of its annual revenue to R&D. We continuously invest in advanced global technologies. Our sealing products utilize specialized equipment and engineering designs from DMH Company in Austria. Furthermore, our hydraulic hose production base is equipped with a complete production line imported from Italy, ensuring our products match the highest international standards.
Over 500 total employees, nearly 180 engineers and technicians, and a dedicated R&D center backed by 7%+ annual R&D investment. We provide robust, custom production capabilities.
We hold ISO 9001 and IRIS (International Railway Industry Standard) certifications. Our professional team performs checks at every manufacturing stage to guarantee product reliability.
Powered by a large workforce and extensive mechanical automation, we manufacture a wide range of custom polymer seals and fluid components to meet diverse industrial demands.
Our sealing products utilize production processes from Austria's DMH. Our hydraulic hose production base uses a complete line of equipment imported from Italy.
The term "cheap" in the context of modern industrial machinery does not mean a compromise on quality. Instead, it refers to structural cost efficiency achieved through supply chain integration, regional raw material availability, and highly optimized manufacturing processes.
In Shaanxi Province—a major hub for China's energy sector—Kelong benefits from a highly integrated supply network. We source raw polymers, high-tensile metal braids, and specialty chemicals at competitive costs. Our high automation levels and integrated R&D processes lower overall production costs.
By combining domestic supply chain advantages with European machinery (such as our Italian hose lines and Austrian DMH sealing systems), Kelong offers globally competitive pricing while maintaining reliable performance under heavy loads.
Different global mining environments present distinct challenges for equipment performance:
When procuring coal mine support handling equipment and high-pressure fluid connectors, purchasing officers should focus on Total Cost of Ownership (TCO) rather than just initial purchase prices. Key evaluation factors include:
