Top-tier industrial components and machinery for longwall operations
Longwall mining remains the most productive underground coal mining method globally, contributing to over 50% of underground production in major markets like China, the United States, and Australia. As the industry faces deeper seams and more complex geological conditions, the demand for robust Longwall Mining Handling Systems has surged. Modern systems are no longer just about moving material; they are integrated, AI-driven environments where safety and efficiency are paramount. Companies worldwide are seeking "cheap" solutions—not in terms of quality, but in Total Cost of Ownership (TCO), prioritizing durability and reduced downtime over low initial price tags.
Automation and remote operation are the core drivers. Integration of IoT sensors in hydraulic seals and hoses allows for real-time monitoring, preventing catastrophic failures in deep-mine environments.
Emerging markets in Southeast Asia and Africa, alongside traditional giants like India and Russia, are driving procurement needs for reliable auxiliary transportation equipment like LWC Chock Carriers.
International safety certifications (ISO, IRIS) are non-negotiable. Handling systems must withstand extreme pressures and corrosive environments while ensuring zero-harm to the operators.
Founded in 1996, Kelong has evolved from a specialized research institute into a global powerhouse in mining technology. As a Top 3 domestic coal machine sealing company, we specialize in R&D, manufacturing, and sales of high-pressure hydraulic sets and auxiliary mining equipment.
Our 28-year journey has been defined by innovation, with over 7% of annual revenue reinvested into R&D. We don't just supply parts; we provide engineered solutions for the world's most demanding mining environments.
Combining European technology with Chinese manufacturing efficiency
Our sealing products are manufactured using state-of-the-art equipment and production logic from DMH Company in Austria, ensuring precision and longevity.
Our high-pressure hydraulic hose production base utilizes a complete set of equipment imported from Italy, meeting the highest international pressure standards.
With R&D personnel accounting for 17.5% of our staff, we are at the forefront of material science, developing NBR, POM, and TPU seals that outlast competitors.
Our solutions in action across diverse industries
In the competitive landscape of Longwall Mining Handling Systems Companies, the differentiator is the ability to provide localized solutions. For instance, in deep Chinese coal mines, the use of WC50Y(B)-50T Hydraulic Longwall Chock Carriers has revolutionized the speed of face transfers, reducing equipment relocation time from weeks to days. This localized success is now being exported globally.
The "China Advantage" in the mining sector has shifted from low cost to High-Value Engineering. Shaanxi Kelong exemplifies this by offering:
Our products are engineered for versatility across several high-stakes environments:
1. Underground Mechanized Mining: Our WC55E Shovel Loaders and Chock Carriers facilitate the auxiliary transportation of heavy supports, ensuring that the main production line never stops.
2. Civil Aviation & High-Speed Rail: The same precision engineering used in our KL58 PTFE Guide Rings is applied to hydraulic systems in transport infrastructure, proving our cross-industry reliability.
3. Heavy Engineering Machinery: Our wear-resistant seals and guide rings are the silent heroes in TBM (Tunnel Boring Machines) and large-scale excavators.
