Detailed Product Description

 Main Features

1.It is a full hydraulic operated top drive power head drilling machine. Its main hydraulic component (hydraulic motor and pump, hydraulic operating valve etc.) adopted world-famous brand goods, so it has stable performance, reliable product quality and long life.

2.It has a wide range of rotary speed which can be changed from high to low steplessly, and is suitable for various drilling methods such as carbide bit drilling and diamond bit drilling etc.

3.Rig structure is a block structure design. It assures good disassemblies, rapid and convenient mounting and transportation, as well as remote control and operation. So it is suitable used for core drilling in tunnel. The machine in combination with drilling mast can be mounted on heavy-duty wheeled trailer suitable for towing over rough terrace, so it assures rapid and convenient mount and transport.

4.It is full hydraulic drive and operate, stepless shift, longer feed length, drilling stability and reliability, simple operate, convenient maintain and few wearing part.

5.A series of meter is provided for fine drilling control, such as pressure gauges, bit pressure gauges indicating different pressure, rotary speed and feed speed gauges etc.

6.It has great drilling capability, wide range of application, rapid drilling speed and high drilling efficiency when using wire-line core drilling.
