The global mining and heavy engineering sectors are currently undergoing a paradigm shift towards automation and higher safety standards. Hydraulic support handling systems, which include heavy-duty carriers like the WC50Y and WC60Y series, are at the heart of underground coal mine operations. These systems ensure the efficient transport and installation of hydraulic shields, which protect workers and machinery from roof collapses.
Modern trends focus on "Smart Mining." We are seeing an increased demand for handling systems integrated with IoT sensors that monitor oil pressure, temperature, and structural integrity in real-time. Electrification is another major trend, as mining companies look to reduce underground emissions. As a result, exporters are now providing hybrid or fully electric hydraulic support hauler solutions to meet carbon-neutral goals.
Global procurement officers from regions like Australia, Russia, and South Africa are increasingly seeking high-durability seals and hoses. They prioritize components that comply with SAE 100 and EN 856 standards to ensure longevity in extreme environments. Cost-effectiveness is no longer just about the initial price but the Total Cost of Ownership (TCO), making high-quality Chinese manufacturing more attractive than ever.
Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, growing from the Xianyang Kelong Rubber Products Institute. We are a technological innovation company integrating R&D, production, and sales. We concentrate on hydraulic seal sets, high-pressure hoses, coal mine auxiliary transportation equipment, and technical services.
Our products are widely applied in coal mining, civil aviation, high-speed railways, engineering machinery, and wind power. As one of the top three in the domestic coal machine sealing industry, we are projected to lead the high-pressure rubber hose and frame-type handling vehicle market within two years.

Our sealing products adopt high-end equipment and production technology from DMH Company in Austria, ensuring precision that meets international heavy-industry requirements.
Our hydraulic hose production base utilizes a complete set of equipment imported from Italy, allowing us to produce ultra-high pressure spiral hoses with zero leakage and extreme wear resistance.
With over 7% of annual income reinvested into R&D, we stay at the forefront of material science, specifically in low-swelling guide rings and oil-resistant rubber compounds.
Choosing a Chinese exporter like Kelong means accessing a robust supply chain that bridges the gap between affordable pricing and premium European technology. Our localization efforts include designing equipment specifically for the deep-well conditions of the Russian Kuzbass region and the open-cut mines of Australia. Whether it is a WC55Y(A)-55T support truck or custom KDAS seal kits, we provide tailored solutions that Western competitors often cannot match in agility or price.
Over 500 employees and nearly 180 engineers ensure that our production capacity meets the heavy demands of global mining hubs.
With ISO and IRIS certifications, our professional team conducts strict checks, guaranteeing top-notch quality for every hydraulic seal kit.
Substantial R&D input allows us to manufacture various specialized products like the KL56 guide ring and oil-resistant KE5611 hoses.
The term "Cheap Hydraulic Support Handling Systems" often gets misinterpreted as low quality. However, in the context of Chinese exporters like Shaanxi Kelong, "cheap" refers to a strategic cost advantage derived from massive scale and vertically integrated manufacturing. Handling systems for coal mine hydraulic supports are the backbone of longwall mining. Without these robust haulers, moving 50-ton shields through narrow, muddy, and steep underground corridors would be impossible.
In the current industrial landscape, companies in the USA and Germany are moving toward autonomous driving for these support carriers. While the technology is impressive, the purchase price remains prohibitive for many mines in developing nations. This is where Chinese companies excel. We offer WC55Y and WC60Y series haulers that integrate essential safety features—such as multi-disk wet brakes and flameproof diesel engines—at a fraction of the cost of European brands.
Localized application is another area where we provide immense value. For instance, in the South African mining belt, high humidity and corrosive water are major issues. Our response was to develop the KDAS combination PU seal and textile-reinforced hoses like the SAE 100 R6, which utilize specific polymers designed to resist hydrolysis. Similarly, in the Australian Outback, thermal stability is key. Our spiral hydraulic hoses are tested to maintain flexibility at high ambient temperatures while carrying high-pressure petroleum-based oils.
Furthermore, the metallurgical industry relies on our PSZ Metallurgy Mechanical Seal Kits. These are used in blast furnace hydraulics where standard seals would fail due to the intense heat and airborne particulates. By utilizing Italian-imported production lines, we ensure that every seal has the exact geometric precision required to maintain a perfect hydraulic lock, preventing costly downtime in steel mills.
The global procurement trend is also shifting towards OEM Seal Kits. Instead of buying individual components, mining companies prefer complete assemblies that are "ready to install." Kelong's OEM services allow companies to brand our high-performance components as their own, backed by our 25+ years of R&D. Our asset base of 600 million RMB and our team of 180+ engineers stand as a testament to our reliability as a long-term partner in the global hydraulic market.
