*Cutting drilling or cone drilling can be operated in the unconsolidated layer,mud and slag can be discharged.The machine is suitable for drilling in complicated geological conditions.
The rotation machine can rotate,the rising height can be large than 6m ,hence,it is suitable for lowering well pipe.
High hydraulic supporting leg can perform loading and unloading in different sites without the help of crane drill.
