The global coal mining industry is undergoing a significant transformation. As coal reserves in shallow areas diminish, underground mining operations are venturing deeper into the earth, requiring more robust and sophisticated auxiliary transportation equipment. Hydraulic Equipment Carriers, including longwall chock carriers and hydraulic support haulers, have become the backbone of modern fully mechanized mining faces.
From the vast coal basins of Australia and the Kuzbass region in Russia to the emerging mining fields in South Africa and Southeast Asia, the demand for high-capacity carriers (40T to 80T) is surging. Mining corporations are no longer just looking for "cheap" equipment; they are seeking optimized Total Cost of Ownership (TCO), which balances initial procurement costs with long-term reliability and maintenance efficiency.
The industry is moving towards automated and remote-controlled transportation. Modern carriers are being integrated with IoT sensors that monitor hydraulic pressure, engine health, and load stability in real-time. Furthermore, there is a growing interest in hybrid or pure electric drive systems for underground carriers to reduce ventilation costs and improve air quality in the mines.
Global mining companies prioritize equipment that can move massive hydraulic supports (chocks) in a single trip, reducing downtime during longwall face transfers.
Carriers must navigate steep gradients (up to 14 degrees) and narrow tunnels. Our WC series is specifically engineered for these high-stress underground environments.
Safety is paramount. All diesel engines and electrical systems in our coal mine carriers meet stringent explosion-proof standards required for gaseous mines.

Shaanxi Kelong New Materials Technology Co., Ltd. was founded in 1996, growing from the Xianyang Kelong Rubber Products Institute. It is a technological innovation powerhouse integrating R&D, production, and sales.
We concentrate on hydraulic seal sets, high-pressure hoses, and coal mine auxiliary transportation equipment. Our products are widely trusted by customers in coal mining, civil aviation, high-speed railways, and engineering machinery worldwide.
Our sealing products utilize equipment and production technology from DMH Company in Austria, ensuring world-class precision.
Our hydraulic hose production base adopts a complete set of advanced manufacturing equipment imported from Italy.
We invest over 7% of annual income into R&D, keeping our technology at the forefront of the coal machinery industry.
Ultra-tough, high-pressure hydraulic hose for rock-solid machinery performance in deep-shaft mining.
Rigorously tested, this hose stays stable under extreme load conditions and vibration.
Innovative design: combines flexibility and strength, easy to install in corrosive saltwater environments.
Upgrade your equipment's efficiency with our high-pressure hose designed for high-altitude maintenance.
When global procurement teams look for Cheap Hydraulic Equipment Carriers For Coal Mines, they often face a dilemma: lower cost vs. high risk of downtime. Shaanxi Kelong bridges this gap by offering "Factory Direct" pricing without compromising on the technical standards of European equipment. Our production lines, featuring Italian and Austrian technology, allow us to manufacture high-spec haulers (like the WC80Y) that compete directly with Western brands at a fraction of the cost.
A carrier is only as good as its hydraulic heart. Our carriers feature multi-layered spiral hydraulic hoses (SAE 100 R12, EN 856 4SH) and high-performance PU seals (KDAS). These components are critical for maintaining pressure in the braking systems and the lift-and-carry frames of the support haulers. In the harsh conditions of a coal mine, where dust and temperature fluctuations are constant, our proprietary sealing technology ensures that the hydraulic system remains leak-free for extended periods.
Whether it's a "low seam" coal mine in the US or a "deep shaft" operation in China, our engineers can customize the carrier's dimensions and load capacity. For example, our WC55E Shovel Loader is specifically designed for mechanized auxiliary transportation, capable of handling less than 55 tons in tight underground quarters where maneuverability is key. This level of localization makes us a preferred exporter for mining groups globally.
Our commitment to quality is backed by ISO and IRIS certifications. With over 180 engineers and a dedicated R&D center, every vehicle and component undergoes a "Zero Defect" check before leaving our facility. We understand that in coal mining, equipment failure isn't just a financial loss—it's a safety hazard. That's why we maintain a top-three position in the sealing industry and are rapidly becoming a global leader in frame-type handling vehicles.
