In the high-stakes world of underground mining and heavy civil engineering, Heavy-Duty Hydraulic Support Trucks (often referred to as shield haulers or frame-type handling vehicles) represent the backbone of logistics. As global demand for raw materials surges, the requirement for vehicles that can transport 50-100 ton hydraulic roof supports safely through narrow, unstable corridors has never been more critical.
Shaanxi Kelong New Materials Technology Co., Ltd. has stood at the intersection of material science and hydraulic engineering since 1996. Our expertise in high-pressure sealing and hose technology is what keeps these gargantuan trucks operational in the most hostile environments on Earth.
Modern procurement is shifting toward autonomous and semi-autonomous support trucks. This requires hydraulic systems with integrated sensors (Smart Seals) that can provide real-time feedback on pressure drops and wear levels.
To reduce carbon footprints in underground mines, "E-Hydraulics" are emerging. Kelong is leading the way with low-friction PTFE seals and high-efficiency hoses designed for the precise control required by electric-hydraulic actuators.
Whether it's the high-salinity of offshore rigs or the abrasive dust of coal mines, components must last longer. Our use of DMH Austria technology ensures our seals withstand pressures that would cause standard PU to fail.
Shaanxi Kelong New Materials Technology Co., Ltd. grew from the Xianyang Kelong Rubber Products Institute. Today, we are a top-three player in the domestic coal machine sealing industry. Our focus extends beyond just parts; we provide macro-industrial solutions for Coal mining, Civil Aviation, High-speed railway, and Wind Power.
With production equipment imported from Italy and sealing technology from DMH Austria, we bridge the gap between "Cheap" pricing and "High-End" performance. We understand that in heavy-duty transport, a single hose failure can cost thousands in downtime.
Ultra-tough hoses for rock-solid performance in deep-vein coal extraction.
Stabilizing heavy-lift support trucks under extreme incline conditions.
Corrosion-resistant hydraulic solutions for maritime support logistics.
Precision seals for pitch and yaw systems in mega-scale wind turbines.
We invest 7% of revenue annually to develop next-gen PU and PTFE composites that offer 30% higher abrasion resistance than standard industrial seals.
Our hydraulic hose production base utilizes a complete set of equipment imported from Italy, ensuring precision braid angles and superior bonding strength.
Adhering to International Railway Industry Standard (IRIS) and ISO certifications, we provide localized support that meets the legal and safety requirements of EU, US, and AU markets.
