Product Advantages:
Designed specifically for underground mining operations, this hydraulic excavator excels in roadway maintenance, drainage trench excavation, coal slag clearance, debris removal, and surface leveling tasks.
The upper frame enables unrestricted 360° rotation for excavation and crushing operations beneath conveyor systems. Its articulated working arm facilitates obstruction-free crushing and digging across full operational ranges at variable heights within mine roadways.
The unit features an air-start ignition system for rapid cold-weather activation, complemented by an advanced water scrubber exhaust treatment system. This emissions control technology converts hazardous engine exhaust into non-toxic gases, significantly improving air quality in underground workspaces.
Product Introduction:
Our High Efficiency Diesel Excavator For Mining which is specifically designed for roadway maintenance, drainage trench excavation, coal slag clearance, debris removal, and roadway leveling in underground environments.
Engineered with materials and components resistant to harsh underground conditions, this compact machine features exceptional maneuverability in tight spaces. It achieves full rotation within minimal cross-sections while performing diverse operations, including excavation, floor leveling, side digging, rock breaking, and material loading. Capable of handling rough drainage trenching, coal slag clearance, debris removal, and roadway grading.
The upper frame supports 360° rotation for under-conveyor crushing and excavation. The working arm enables obstruction-free, full-range crushing and digging at varying heights in roadways. A front-mounted adjustable dozer blade stabilizes the machine and assists in roadway leveling. Hydraulic lines on both sides of the working arm are protected by spring-reinforced sleeves to prevent hose damage.
Equipped with an advanced load-sensing hydraulic system, this technology automatically matches pump pressure to operational demands while precisely controlling load speed. Recognized as the state-of-the-art hydraulic solution in modern construction machinery.
Features an air-start system for rapid and convenient ignition, paired with an advanced exhaust treatment system (water scrubber) that neutralizes harmful engine emissions into non-toxic gases, ensuring a cleaner working environment.
