The global mining industry is undergoing a paradigm shift towards mechanization and safety-first logistics. Hydraulic underground support handling equipment, particularly longwall chock carriers and hydraulic support trucks (like our WC60Y and WC50Y series), are the backbone of modern coal mining. In deep-shaft mines across Australia, Russia, South Africa, and the USA, the demand for high-tonnage (40T to 80T) handling equipment is surging.
These machines are not just vehicles; they are specialized logistical tools designed to operate in low-clearance, explosive-prone environments. The integration of high-pressure spiral hydraulic hoses (SAE 100 R12) ensures these carriers maintain peak lifting power even under extreme geothermal heat and abrasive dust conditions found 1,000 meters below the surface.
Global mining firms in methane-rich environments prioritize equipment with certified diesel-engine flameproof systems. Our WC series loaders meet these rigorous safety standards for coal-gas outburst mines.
Procurement teams are shifting focus to multi-purpose vehicles. The ability to switch between a shovel loader and a support carrier (30T-80T) offers immense flexibility for auxiliary transportation.
In humid local mines, hydraulic piston failure is common. Demand for Austrian DMH-tech KDAS seals is at an all-time high to prevent downtime in critical hydraulic support circuits.
Founded in 1996, we have grown from a rubber research institute into a global powerhouse in hydraulic seals, high-pressure hoses, and underground transportation equipment.
Our hydraulic hose production base utilizes full sets of equipment imported from Italy, ensuring precision and reliability.
ISO and IRIS certified operations. Our sealing products utilize Austrian DMH Company's technology for zero-leakage performance.
With an annual output of 300 million RMB, we have the scale to provide cheap factory-direct quotes while maintaining premium engineering standards.
17.5% of our staff are R&D personnel, focusing on the next generation of autonomous underground handling vehicles.
Ultra-tough, high-pressure hydraulic hose for rock-solid machinery performance in deep-level extraction.
Rigorously tested hose stability under extreme conditions for heavy lifting in coal face relocation.
Innovative designs combining flexibility and strength, proving our seals' capability in saline offshore environments.
Applying high-pressure hydraulic efficiency to renewable energy equipment's pitch and yaw systems.
The industry is moving toward Industry 4.0 integration. Future hydraulic support trucks will feature real-time sensor feedback through IoT-connected hydraulic hoses, alerting operators to pressure drops or seal wear before a breakdown occurs. Kelong is currently developing "Smart Handling" prototypes that will enter the market within the next two years, aiming to secure our position in the global top three for frame-type handling vehicles.
We are also focusing on eco-friendly diesel technologies and electric-drive shovel loaders to meet the growing demand for green mining operations. By reducing emissions in confined underground spaces, we not only protect the environment but also lower the ventilation costs for mine operators.
With over 25 years of experience, Shaanxi Kelong New Materials Technology Co., Ltd. is not just a supplier but a strategic partner. We share 8% of the domestic market and are rapidly expanding internationally. Our mission is to combine Italian precision equipment, Austrian sealing technology, and Chinese manufacturing efficiency to provide you with the most competitive Hydraulic Underground Support Handling Equipment quotes in the industry.
Whether you require a WC80Y-80T heavy-duty truck or high-pressure wire spiral hoses for petroleum-based oils, our team of 180 engineers is ready to customize solutions for your specific mine conditions. We sincerely welcome you to visit our facility and cooperate with us to create a brilliant, safer, and more efficient future for global mining.
