Diesel Mining Excavator
1. Diesel engine power, no need for external power supply.
2. Strong hydraulic system, with great digging force.
3. Specifically designed for underground use, with a compact and low-profile body.
4. Explosion-proof, in compliance with underground mining safety standards.
Applications and Features
The Diesel Mining Excavator is a multi-functional tunnel repair equipment that can perform tasks such as excavation, side digging, flipping, and loading. It features a compact body design and is capable of fulfilling functions like clearing and leveling the tunnel inside the mine. As a diesel-powered hydraulic excavator, it has low energy consumption. All the power is concentrated in a power module, and the hydraulic system is advanced, controlled by a pilot valve. The operation is easy and simple, with smooth and impact-free operation. The mechanized tunnel excavation process can significantly enhance the efficiency of tunnel repair work.
