Large Diesel Power Core Drilling Rig Mineral Exploration Drilling Rigs

Large Diesel Power Core Drilling Rig Mineral Exploration Drilling Rigs

Description:

Our GY-300A is a shallow/middle-hole core drill. It is applicable to not only the core drilling of small or big diameter with carbide and diamond bits, but also the engineering geological exploration and the construction engineering, hydropower engineering, highway/railway construction, port construction, etc. The outline is shown in Drawing 1.

Features:

1. Rotation speeds of the drill rig are in a wide range (eight gears) and the speed distribution is rational;

2. It is characterized by low rotation speed and big torque and wide applicable range. It can be applicable to the low-speed big-diameter drilling besides the rapid-speed drilling;

3. It is of two-gear reverse speeds, with lower labor intensity and safe operation when dealing with the in-hole accident;

4. It has a large installed power and it is adapted to diesel engine or electric motor;

5. It features in advanced structure, rational layout, flexible and reliable operation, and is easy for repair and maintenance;

6. The drill rig is small in volume, light in weight, and easy to be disassembled and moved;

7. Feeding travel of the vertical shaft is 600mm, which benefits raising the drilling efficiency and reducing the possibility of drill pipe sticking;

8. Stable for moving, simple and reliable for fixing of drill rig, good stability for high-speed drilling, and a big distance between drill and hole;

9. Drillometer uses the oil-filling and anti-shock structure, with simple scale value, accurate indication and long service life.

10. The hydraulic plunger chuck is adopted, with reliable clamping operation and free from damaging the driving drill pipe;
