9.5 m Digging Depth Mine Excavator
Company: Jinan Tui Wa Import and Export Trading Co., Ltd. (TUIWA)
For large-scale open-pit mining, underground ore extraction, overburden stripping, and deep foundation excavation in mining projects, high-performance, deep-digging machinery is essential. TUIWA is proud to introduce our 9.5 m digging depth mine excavator, a specialized heavy-duty machine designed for deep excavation, high-volume ore handling, and continuous heavy-duty operation in harsh mine environments, including open-pit coal mines, metal ore mines, and quarrying sites. With a 9.5-meter maximum digging depth, reinforced structural design, and efficient power system, this model delivers reliable deep excavation performance, strong load-bearing capacity, and excellent durability to meet the rigorous demands of mining operations.
Why 9.5 m Digging Depth Mine Excavators Stand Out
Standard excavators with shallow digging depths (less than 8 meters) cannot meet the deep excavation needs of modern mining projects, such as deep ore layer extraction, large-scale foundation digging for mine infrastructure, and overburden stripping in deep open-pit mines. The 9.5-meter digging depth is specifically optimized for mining scenarios, striking an ideal balance between deep-digging capability, operational stability, and work efficiency—filling the gap between shallow-duty excavators and ultra-large mining machinery.
Compared with larger mine excavators (with digging depths over 12 meters), this 9.5 m model offers more flexible operation, easier transportation, and lower fuel consumption, while still delivering sufficient deep-digging performance for most medium-to-large mining projects. Compared with standard construction excavators, it features reinforced structural components, wear-resistant materials, and a high-power system, enabling continuous heavy-duty operation in harsh mine environments with dust, rock impacts, and extreme temperature variations. The 9.5-meter digging depth ensures efficient extraction of deep ore layers and completion of deep excavation tasks in a single operation, eliminating the need for repeated repositioning and significantly improving work efficiency.
TUIWA 9.5 m Digging Depth Mine Excavator – Built for Deep Mining Efficiency
TUIWA’s 9.5 m digging depth mine excavator features a reinforced heavy-duty undercarriage, high-strength boom and arm, large-capacity rock bucket, and powerful power system. Engineered for continuous heavy-duty mining operations, this machine combines deep-digging capability, stable operation, and efficient material handling, tailored to the unique challenges of mine excavation and ore processing.
Key Features and Benefits
9.5-Meter Digging Depth for Deep Mining Needs
The optimized boom and arm design (boom length 6.8-7.2m, arm length 3.5-3.8m) enables a maximum digging depth of 9.5 meters, perfectly adapting to deep ore layer extraction, overburden stripping, and deep foundation excavation in mining projects. This deep-digging capability eliminates the need for multi-machine coordination or repeated excavation, reducing operation cycles and improving overall mining efficiency. The precise depth control system ensures accurate excavation, avoiding over-digging or under-digging and reducing ore loss and engineering waste.
Heavy-Duty Power System for Continuous Operation
Equipped with a high-power diesel engine (220-260 kW, 295-354 HP) from internationally renowned brands (Isuzu, Cummins, or Weichai), the excavator delivers strong torque and stable power output, ensuring continuous operation even in high-load, long-duration mining tasks. The engine adopts advanced fuel injection technology and turbocharging system, achieving full combustion of fuel, reducing fuel consumption by 8-12% compared with similar models, and meeting Euro IV/Stage III emission standards to comply with global environmental requirements for mining operations. For large-scale mining sites, an optional electric drive system (315 kW) is available, realizing zero emissions, low noise, and lower long-term operational costs.
Reinforced Structural Design for Mine Durability
Targeting the harsh mine environment, the excavator adopts a reinforced structural design to resist wear, impact, and corrosion. The boom and arm are made of high-strength Q355B steel with thickened plates and reinforced welding, enhancing resistance to bending and impact during heavy-load digging and rock breaking. The rock bucket is equipped with wear-resistant alloy teeth and a thickened bucket bottom, extending service life by 50% compared with standard buckets and adapting to the abrasive nature of ore and rock materials. The heavy-duty undercarriage features reinforced track frames, large-diameter rollers, and wear-resistant track shoes (600mm width), ensuring stable operation on uneven, rocky mine terrain and resisting damage from sharp rocks and debris.
Efficient Ore Handling and Loading Performance
The excavator is equipped with a large-capacity rock bucket (1.8-2.2 m³), enabling high-volume ore loading and transfer with each cycle. The advanced load-sensitive hydraulic system delivers fast, smooth operation, reducing the time per excavation cycle and improving hourly output. The hydraulic system adopts high-pressure hoses and imported valves (Eaton, Kawasaki), ensuring reliable operation under high pressure and reducing hydraulic failure rates. In practical applications, the machine can complete 80-100 excavation cycles per hour, with an hourly ore handling capacity of 150-200 cubic meters, significantly improving mining production efficiency.
Stable Operation and Safety Protection
The 9.5 m digging depth mine excavator features a low center of gravity design and a wide track gauge (2.8-3.0m), ensuring exceptional stability during deep digging and heavy-load operation, preventing tipping on uneven or sloped mine terrain. The ROPS/FOPS-certified cab provides comprehensive safety protection for operators, with impact-resistant glass and a reinforced frame to withstand falling rocks and debris. Safety features also include emergency stop systems, overload protection, anti-slip track design, and a rearview monitoring system, ensuring safe operation in complex mine environments.
Precise Control and Intelligent Operation
Advanced electronic control and hydraulic systems deliver precise control over digging depth, bucket speed, boom positioning, and travel functions. The intelligent operation system allows operators to set excavation parameters (depth, angle) in advance, realizing semi-automatic excavation and reducing operational errors. The cab is equipped with a high-resolution color display, real-time monitoring of engine speed, hydraulic pressure, fuel consumption, and fault information, enabling operators to grasp the machine’s working status at any time. Optional remote monitoring and remote control functions allow for remote operation in dangerous mining areas, reducing safety risks to operators.
Operator Comfort and Easy Maintenance
The ergonomic cab is designed for long-duration operation, with a low-vibration seat, adjustable steering wheel, air conditioning, and noise reduction design (noise level ≤75dB), reducing operator fatigue. The cab features large-view windows and a 360° viewing system, ensuring excellent visibility for safe operation. All key maintenance points (engine oil, hydraulic oil, filter elements) are easily accessible, with a modular design that simplifies maintenance procedures and reduces maintenance time. The machine is equipped with a centralized lubrication system, automatically lubricating key components and extending service life.
