Product Description

Underground Core Drilling Rig

Product Description

RCH-3A hydraulic underground drill rig is mainly suitable for coal, geological, metallurgical, engineering, and other industries. Used in mines, tunnels, the coal mine gas drainage by large-diameter gas holes, water injection hole and surface engineering of large diameter horizontal drilling construction.,It is also used to the large-diameter horizontal drilling of the surface engineering. The full hydraulic underground drilling rig can accomplish large-diameter cone drilling, large-diameter hard-metal drilling, and percussive-rotary drilling.
 

Our Advantages

1. The full hydraulic underground core drilling rig is a split-type layout. This, along with its lightweight, makes its transportation effortless, its operation flexible.

2. The feeding and rotation function of the unit head is accomplished like this: the explosion-proof motor and control system of the power unit puts the hydraulic pump in motion. Thus, the hydraulic fluid comes into being. By means of the hydraulic fluid, the motor makes the spindle rotate, and the multi-speed mechanism of the hydro-cylinder chain work.

3. The hydraulic chuck can accomplish the clamp and break out of the drilling rod as well as the function of block-out prevention.

4. The mast slide itself. The underground diamond core rig can also stretch out and drawback. This maintains a close touch between the mast and the foundation. As a result, the underground core drilling rig will have enhanced stability.

5. The up-and-down swing of both the mast and the swing frame ensures the drilling from multi-angles.

6. The spindle of the unit head has a wide range of rotary speed, thus a large rotary torque.
