HCDF-6 Hydraulic Core Drilling Rig
Description
HCDF-6 type machine has a drilling capacity of 3000 m. The quadrangle derrick and the full hydraulic main machine are separately arranged. This hydraulic core drilling machine is composed of diesel engine, feeding system, hydraulic system, control system, main winch, wire line winch, unit head and wellhead clamp. This machine mainly applied to the exploration in the fields of mining geology, environmental geology and engineering geology. It is widely used in the exploration projects of geological minerals, coalfield, nonferrous metals, nuclear industry, gold and other fields.
Features
- 1. This drilling rig has the characters of long stroke feeding and stable pressure. Drilling accidents has been reduced and drilling efficiency has been improved.
- 2. Infinitely variable speed is available. This hydraulic core drilling machine has a wide range of speeds. It can change the speeds smoothly.
- 3. This drilling rig has overload protection. It can realize large torque at low speeds.
- 4. This machine has large normal diameter chuck. It is suitable for PQ, HQ, NQ and BQ drilling construction.
- 5. With the independent operation platform, the operations are very convenient. Monitoring instrument is used for monitoring the whole operation and working condition inside the holes.
- 6. Key parts of the machine are reliable. Hydraulic pump, valves and motor are from famous suppliers.
- 7. Accessories like gripper, mud pump and stirrer are all hydraulic controlled.
- 8. This hydraulic drilling machine has reserve the advantages of hydraulic drilling rig and absorbed the advantages of high drill tower used in deep-hole drilling rig.
- 9. The feeding cylinder of the machine has great pulling force. Its feeding stroke reaches 4.8 m. It is suitable for 3m rope and 4.5 m rope.
- 10. The coring drill rod can achieve a whole pipe core just in one roundtrip. This character helps improving the coring efficiency.
- 11. With the combination of mechanical gear shift and hydraulic speed governing and function of electric digital display, speed of this machine can be varied accurately and infinitely between 0 and 1200 rpm.
- 12. The hydraulic chuck is safe and reliable. It has five hard alloy clips inside. Its maximum clamping force reaches 360 KN. It is very convenient to disassemble and change different clips units.
- 13. This machine also has a standby upper section of the mast. One machine can achieve two purposes.
