Shaanxi Kelong New Material Technology Co., Ltd. was established in 1996 as a leading high-tech enterprise integrating research & development, precision manufacturing, and global sales services. The company specializes in advanced combined sealing products, high-pressure hydraulic hoses, and durable longwall chock haulers primarily serving the coal mining industry. Its products are robust and reliable, designed to meet the extreme demands of underground coal mining and longwall face operations. Beyond mining, Kelong’s technologies are applied to metal mining, civil aviation, high-speed railway, wind power, and other critical infrastructure sectors.
Leveraging German DMH company’s cutting-edge sealing technology and production equipment from Austria, as well as high-performance hydraulic hose manufacturing lines imported from Italy, Kelong boasts an annual output exceeding 15 million meters of hydraulic hoses. The firm generates over 58 million USD in annual revenue and employs more than 500 skilled personnel, including an independent R&D center which dedicates over 5.6% of total yearly revenue towards innovative product development. This commitment enables Kelong to provide tailored OEM and ODM services to meet the evolving needs of global customers, including coal mining enterprises across Asia, Oceania, and Eastern Europe, holding ISO and IRIS certifications.
Presently, Kelong’s total assets value approximately 600 million RMB with annual output value reaching 300 million RMB. The workforce comprises more than 400 employees, including nearly 180 engineers and technical experts. Over 40% of employees hold college degrees, with research and development staff accounting for 17.5% of personnel. The company has increased its R&D investment to over 7% of annual income within the past three years, strengthening its technological leadership.
Kelong ranks among the top three manufacturers in China’s coal machine sealing sector. Its high-pressure rubber hoses and frame-type handling vehicles are on a rapid trajectory to enter the top three rankings within two years. The company’s main product line commands approximately an 8% share of the domestic market. With sustained focus on technological innovation, the company aims to continually enhance product performance and maintain a cutting-edge position within the industry. Visitors and business partners are warmly welcomed to explore collaboration opportunities for mutual development.
Kelong New Material is a dynamic manufacturer and distributor specializing in sealing and hydraulic hose systems tailored to industrial requirements. Possessing an independent R&D and technology center, the company supports OEM and ODM projects with customized product development aligning with customers’ operational environments and technical demands.
The sealing products integrate the precision equipment and production technologies from DMH Company in Austria, ensuring industry-leading performance and durability in challenging underground mining environments.
Kelong’s hydraulic hose production base uses a complete set of cutting-edge equipment imported from Italy, enabling the manufacture of high-quality, reliable hoses with consistent quality and performance.
Underground coal mining is one of the most demanding environments for hydraulic equipment due to extreme conditions including high pressure, abrasive dust, moisture, and vibration. Custom hydraulic hoses tailored specifically for this industry provide the backbone for safe and efficient operation of mining machinery such as hydraulic supports, longwall shearers, and chock haulers operating on the coal face.
The mining industry continues to demand increasingly rugged hydraulic hoses capable of withstanding high working pressures exceeding 40 MPa, extreme flexibility for confined spaces, and chemical resistance against hydraulic fluids and environmental contaminants. Recent industry trends focus on:
Commercially, the emphasis is increasingly on lifecycle cost savings, where investing in premium custom hoses brings longer intervals between maintenance and replacements, ultimately delivering substantial operational cost efficiencies and enhanced safety.
Custom hydraulic hoses are critical in multiple specialized mining equipment:
Looking forward, the development of hydraulic hoses embedded with smart materials and IoT-enabled sensors will revolutionize underground coal mining operations by enabling predictive maintenance and improving system uptime.
