 The advantages of XZ450 HDD Drill Rig

1. Using closed loop circuit and load sensitive control and electro-hydraulic proportional control and a number of advanced control technology. The imported components is reliable in quality;
2. The rack pinion push and pull, which ensures the stability and the reliability of the transmission of power head operation. Power head floating can greatly protect the drill pipe thread and improve the service life of the drill pipe;
3. Selection of main components of international and domestic first-class form a complete set of hydraulic components manufacturer and improve the reliability of the product;
4. You can choose the optional power power head which can double head back to the drag force. We can meet customer’s special requirements;
5. The work station adopts the man-machine engineering design, more comfortable and convenient;
6. Wire-control walking ensure the safety of the walking process;
7. Narrow fuselage design and the container transportation can be realized.
