Product Advantages:
The machine is suitable for rock loading, bottom cleaning and excavation of frozen soil in coal mines, metal mines, non - metallic mines, shafts, inclined shafts and flat tunnels. Compared with the traditional manual bottom cleaning, the use of the machine greatly saves labor costs while improving the operation efficiency and improving the working environment.
The operator works under the protection of the cab, which is conducive to safe production. Compared with the traditional diesel - powered mini excavator, due to the use of electro - hydraulic system, this machine has the characteristics of energy saving, low noise, no exhaust gas pollution and high efficiency, and is more suitable for underground use.
The machine has compact structure, small size and small sub - assembly parts, which is convenient for vertical use. This machine adopts the minimum swing structure, and its tail will not exceed the width of the car when the body is rotated, so it is more suitable for the narrow space underground.
Product Introduction:
Our Explosion Proof Diesel Excavator For Mining which is engineered for subterranean mining operations, this hydraulic excavator is optimized for roadway maintenance, drainage trenching, coal slag removal, debris clearance, and terrain leveling. Constructed with reinforced, corrosion-resistant components to withstand extreme underground conditions, its compact architecture ensures unparalleled maneuverability in confined workspaces. The unit achieves unrestricted 360-degree swivel within limited cross-sectional zones, enabling simultaneous execution of excavation, grading, lateral digging, rock fracturing, and material transport. It is purpose-built for rigorous applications such as high-resistance trenching, coal byproduct management, waste removal, and roadway conditioning.
The rotating upper frame delivers 360° continuous rotation for uninterrupted excavation and material processing beneath conveyor lines. Equipped with a multi-axis articulated boom, the machine performs obstruction-free digging and crushing operations across adjustable vertical ranges in narrow mine passages. A front-mounted modular blade provides operational stability and assists in fine-grade surface finishing. Dual-side hydraulic circuits along the boom are armored with spring-buffered protective sleeves, ensuring durability in abrasive environments.
Integrated with a smart adaptive hydraulic system, the excavator automatically calibrates pump output to real-time workload demands while ensuring millimeter-level control over load movement and speed. This system sets a benchmark in hydraulic innovation for modern industrial machinery.
The excavator employs a compressed-air ignition system for instant cold-start capability, paired with a high-efficiency aqueous scrubber exhaust treatment unit. This dual-phase emission control technology chemically converts toxic combustion byproducts into inert gases, minimizing particulate emissions and ensuring compliance with underground air quality standards.
