1. Fir for wet drilling in medium-hard or hard rock
2. Grouped control mechanism, quick to start up. with " air on, water on, air off, water off". mechanism, convenient to handle and essy to maintain and repair.
3. Energy-saving and efficient, long service life of parts which are highly interchangeable and reliable performance.
4. Mining rock drill differ from similar products particularly in its high efficiency strong flushing and powerful torque.
Pneumatic Rock Drill: Pneumatic rock drills are currently the most widely used and most numerous rock drilling equipment for underground rock drilling. Compared with hydraulic, diesel, and electric rock drills, pneumatic rock drills have the advantages of simple structure, lightweight, safety, reliability, sturdiness and durability, strong adaptability, easy processing, and low-cost operation, low maintenance technical requirements, and convenient use.
Hydraulic Rock Drill: The hydraulic rock drill has the advantages of large output power, fast drilling speed, low energy consumption, long life of spare parts, high accuracy of drilling and perfect hydraulic control.
Electric Rock Drill: Electric rock drill is a kind of machinery that relies on the conversion of electric energy into mechanical energy to achieve impact rotary rock drilling.
Diesel Rock Drill: Diesel rock drill is actually a kind of special internal combustion engine. Its biggest feature is that it needs no external energy, flexible and mobile, especially suitable for field operation.
1. Electric rock drill is used for drilling burst mine hole in rock.
2. It is widely used in the mine shaft excavation, road construction, water conservancy construction, metallurgy mining, rock engineering, quarry operation, basic engineering drilling reinforcement construction process.
3. The explosion-proof electric rock drill is used for drilling water injection hole, on coal seam, exploring water holes and discharging gas, also can be used for soft rock tunnel excavation.
4. They can do wet type and dry type work (equipped with twist drill rod). Drills holes horizontally forward or tilt up, only need to control the handwheel, the drill will track forward and backward automatically on the railway.
