1.It has many (8 grade) rotary speed series and reasonable speed range.Not only apply to engineering geological exploration,but also apply to diamond core drilling.

2.Low rotary speed,big torque,wide usage range,it can drill with high speed,also low speed with big hole diameter.

3.Two reverse speed, labour intensity is not big for hole accident,also safe.

4.The structure is advanced,well laid-out,flexible and reliable operation,it is covenient to  maintenance and repair.

5.Hydraulic pressure with strong lifting capacity,tabour saving and safe.

6.Double hoists design,main hoist is  flexible and reliable operation;Vice hoist with big capacity of drum.

7.The power head can move automatically to save labor,extend the performance life.

8.The four ground jack and tower is hydraulic operation,convenient and reliable.

Application:

1. geological prospecting and mineral well 

2.with the liquid and the borehole of earthquake prospecting.

3.The drilling hole for building blaster.

4.  geological exploration or water well.

5.Fit for wire-line core drilling engineering require.

6.Farmland water well, geological prospecting,  Ground Source Heat Pump,roadway,bridge etc.
