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.
