PRODUCT FEATURES
1.The equipment is small in size and flexible in movement, facilitating tramming in narrow tunnels and site transfer.
2. It is specially designed for driling in narrow drift stopes, capable of operating in heights around 3 meters, supporting drilling and rod extension with depths up to approximately 20 meters;
3. Features of automatic drilling and retraction, anti-jamming, high drilling efficiency, drilling speed greater than 2 m/mnin;
4. The crawler track is used for tramming, with low center of gravity and high stability;
5. The tramming and all actions of the whole machine can be remotely controlled;
6. Electro-proportional hydraulic control ensures stable equipment perfornance, low failure rate, high efficiency and energy saving；
7. The hydraulic system consists of hydraulic pumps (piston and gear types), water-cooled radiators and other key components.
8. The safety protection system function of the electrical system can effectively prevent electrical faults suchas voltage loss, overload,phase loss, short circuit and electric leakage.
