Main characters:
- The maximum speed is up to 170r/min; and comparing to SD-135, the speed has increased by 20%.When construct on soil, using twist drill can make the drilling efficiency more impressive.
- Energy-saving, high efficiency: Although the power remains the same, the work efficiency is highly improved.
- Compared to SD-135, the speed increases, and the torque has increased by 10% while the maximum rotary torque can achieve 7500NM.
- With the new hydraulic system, the structure is simpler, the layout is more reasonable and the operation is more humanized
- Compared to SD-135 drilling rig, the drilling efficiency enhances by 20% or more.
Based on different stratum, we can adjust torque and rotary speed of drilling rig to increase drilling rig’s adaptability.At the same time, we can adjust torque and rotary speed according client’s request.
With the crawler, it has the following technical features: fast mobility, accurate location, time saving, good reliability and stability. It can also reduce labor intensity and increase efficiency after equipping the clamping and breaking device .
Our R&D department also develops relative drilling tools to meet the following construction technology:
1. Anchor;
2. Jet-grouting;
3. Mud Positive circulating Drill;
4. DTH hammer impact Drill by Air;
5. DTH hammer Impact Drill by Water;
6. Multi-liquid Reverse Circulating Drill.
