Scope of application：

Reverse Circulation Drilling Machine is suitable for large diameter,  ultra-deep or rock-socked pile and other complex geological conditions of  drilling construction. It is widely used in drilling pile foundation of land large  buildings, harbor, wharf, embankment protection, bridge, offshore wind power  station and so on. It is an alternative product of other pile equipment.

Performance characteristics：

1.Full hydraulic power head, large torque, suitable for various  stratigraphic environments, especially for hard rock and other strata  construction.   

2.Full hydraulic stepless speed regulation, according to the working  conditions to adjust the pump and motor displacement, match the constant  power hydraulic pump and diesel engine output power, make full use of the  diesel engine performance, save fuel.  

3.Using high-power diesel engine, suitable for field and offshore  no-power-supply construction. 

4.Tiltable gantry frame and power head, compact structure,  easy-disassemble drilling pipe and bit, safe and reliable. 

5.Color LED controller, monitor the working status of diesel engine and  whole system, safe and intuitive.

6.Modular structure, convenient disassembly and transportation. 

7.High strength operation room, protect the safety of operator. 

8.Various working modes, such as automatic drilling, constant pressure  drilling and manual drilling. Suitable for construction under various  complicated geological conditions.
