Shaanxi Kelong New Material Technology Co., Ltd., established in 1996, integrates R&D, production and global sales operations. With cutting-edge sealing technology licensed from Austria's DMH Company and hydraulic hose manufacturing equipment imported from Italy, Kelong is positioned at the forefront of innovation and quality. The company specializes in sealing products, high-pressure hydraulic hoses, and long-wall chock haulers, serving industries such as coal mining, metal mining, and critically, civil aviation ground support and maintenance equipment.
In the civil aviation sector, ground support and maintenance equipment rely heavily on robust and reliable hydraulic systems to ensure safety, efficiency, and timeliness of aircraft operations. High pressure hose fittings are central components in this ecosystem, tasked with securely connecting hoses that transport hydraulic fluids under intense pressure to power systems like aircraft towing vehicles, cargo loaders, de-icing trucks, and maintenance lifts.
The industry has seen a growing focus on high-performance materials that withstand extreme pressures, corrosive fuels and coolants, and fluctuating temperatures typical of airport ground environments. This is coupled with increasing regulatory standards demanding higher reliability, safety factors, and traceability in hose assembly manufacturing. As a result, suppliers such as Shaanxi Kelong New Material have accelerated development of multi-layered, wire-braided hoses with advanced sealing technologies designed specifically for civil aviation equipment.
Commercial trends indicate a robust growth trajectory driven by global expansion of air travel, which necessitates modernization and replacement of aging ground support fleets. Adoption of next-generation electric and hybrid vehicles in airports also requires hose fittings compatible with novel hydraulic fluids and innovative design standards.
Leveraging the sophisticated sealing technologies provided by DMH Company, Kelong enhances hose fitting durability and leakage resistance even under the demanding pressures of civil aviation ground equipment. These innovations include multi-lip seals with low swelling, temperature-resistant composites, and precision manufacturing that ensure longer service life and minimized maintenance intervals.
Kelong’s hydraulic hose production base utilizes state-of-the-art machinery imported from Italy, enabling the manufacture of wire-braided hydraulic hoses meeting SAE and EN standards. This precision production helps meet the critical dimensional tolerances required for civil aviation ground support applications, ensuring error-free interfacing with OEM equipment and compliance with stringent industry certification requirements such as ISO and IRIS.
In addition to ground support equipment such as fuel trucks, hydraulic stair vehicles, and conveyor loaders, high pressure hose fittings have expanding applications in emergency rescue equipment and airport infrastructure maintenance vehicles. Emerging developments targeting hybrid hydraulic-electric GSE require hose systems to integrate with intelligent monitoring technology for predictive maintenance, a sector where companies like Kelong are investing heavily in R&D.
With total assets reaching 600 million RMB and an annual revenue exceeding 300 million RMB, Kelong is a major player in the domestic sealing and hydraulic hose industry. Its workforce of over 400 employees includes 180+ expert engineers and technicians, emphasizing a strong commitment to research and development. The company's R&D investment represents more than 7% of its annual income, reflecting a strategic focus on innovation to maintain industry leadership.
Kelong is recognized as one of the top three enterprises in sealing products for coal machinery and aims to enter the top three for high-pressure rubber hoses and frame-type handling vehicles within two years. Despite its industrial roots, its advanced technologies and product lines increasingly serve civil aviation ground support markets, bringing durable, adaptive solutions essential for modern airport operations nationally and globally.
Kelong New Material proudly operates its independent R&D and technology centers, providing OEM and ODM services tailored to specific client needs. Their expertise spans the design and manufacture of special hydraulic hose assemblies for challenging environments encountered in civil aviation ground support and maintenance equipment.
