GD2600

1.Hydraulic system: Closed-circuit system is adopted for push-pull rotation walking, with electro-hydraulic proportional control.
2. The machine is equipped with two diesel engines, so one or two engines working is realized to meet different conditions, and it can save energy. If one set hydraulic system or one of the two engines breaks down, the other one can still be operated normally (with the same force and lower speed), which can greatly improve construction safety.
3. Front and back clamping can be separated, and the clamping floats in the whole process.
4. It is equipped with φ127 or φ140 ×9600mm drill pipe. The floating spindle is in favor of protecting drill pipe thread.
5. Floating girder is good for loading, unloading, climbing and transportation, and it is convenient for adjusting entry angle, which can effectively protect clamps.
6. Proportional wire control walking system ensures man and rig safety in the process of walking, loading and unloading.
7. It is equipped with electrical control handle, with simple electric circuit, safe, reliable, and sensitive.
8. The spacious operation cab is equipped with adjustable seat, which is more humanized and more comfortable.
9. To enhance the executing mechanism ability, hydraulic system is designed in conformity to large flow and high pressure. Our self-designed inserting control valve group reacts fast and reduces 50% pressure loss in hydraulic system.
10. Self-designed and developed, combined electronic controlling system realizes its adaptive control to different working condition and different geologic strata，improving the 30% efficiency of construction. The system is configured with both auto-operation and man-operation. Auto-operation could timely adjust the running parameter according to the strata situation and automatically adjust the rig for rig protection.
11. Liquid crystal man and rig exchange system can monitor rig condition at any time, which can adjust rig work and alarm parameter, making operation simpler and more comfortable.
12. Rational and effective washing and cooling system ensures safety, reliability and efficiency of system, extends motor using lifespan, and avoids motor damages.
