High Quality Dra Series Dual Power Drilling Rig - DRA 13/5 Dual Power Drilling – Engineering Machinery Detail:
Product Detail
DRA Series Dual Power Drilling Rig is composed by double rotary heads, advanced electrical control system and tools set including casing tube, drilling auger and DTH hammer. SEMW rig is designed for multi-functional construction, especially for high efficient drilling in complex stratum condition with gravel and hard rock. The drilling rig provides high pile quality, high vertical precision and less mud contamination. SEMW rig solved the technical problems in large diameter pile foundation drilling in rock, overcame the environmental pollution of the bentonite. It is one kind of environment-friendly piling machinery with new technology, which not only complies with the national policy for the energy saving and emission reduction, but also has good economic and international market promotion prospects.

FEATURES
1.Frequency conversion motor, speed adjustment is convenient, performance is stable
The upper and lower power units adopts variable frequency motor to meet the requirement of speed regulation of drill pipe during construction. The motor is special designed for drilling machines. It has high starting torque, high overload capacity, high mechanical strength, stable performance, and can withstand vibration and impact that may be encountered in construction. It is suitable for working under various geological conditions to ensure smooth construction.
2. The upper and lower power units operate independently, the force is balanced and the construction efficiency is high.
The upper and lower power units respectively drive the inner drill pipe and outer casing pipe. The casing will follow the drilling of the drill pipe in the reverse direction to achieve the purpose of wall protection, avoid the collapse of the drill hole, and ensure the perpendicularity of the drill hole. The upper and lower power units drive both drilling tools to be constructed at the same time, and the rate of soil transportation is fast, greatly improving the efficiency of the drill rig.
3. Multi-purpose, meet the requirements of a variety of construction methods
The drill pipe of the upper power unit head can be connected with a variety of actuators to meet the selection requirements of various construction methods, and can be used as a piling drill to realize multi-use, meeting the personalized and diversified development needs of the drill in the future.
