Product Description 

The DHT drilling rig is widely used in small and medium sized mining and national defense, water conservancy, road construction, stonework project blasting hole drilling operations. Is the ideal tool for achieving stratification in deep mining and blasting.

The drilling rig is also an essential rock drilling equipment for the early exploitation of surface mining.

The drilling rig is especially useful for rugged terrain where other drilling rigs can not work.

Main features:

simple structure ,easy operation,low cost.

low center of gravity detachable good,easy relocation of transport,especially for the rugged        terrain irregularities or original landscape.

impactor low air consumption,supporiting the necessary small compressordisplacement,energy economy.

rotary gear torque ,under strong vibration ,high-load operating conditions and reliability.

electrical system with overload protection and phase protection ,so that the rig is stable and reliable.

a propulsion system configured valve ,propulsion force can be adjusted according to different rock conditions,to obtain the best drilling results.

A. Feature of the drill:  

1) Easy operation and high efficiency as the hydraulic feeding be taken.

2) As the ball type chuck and the driving rod, it can complete no-stopping rotating while the spindle relift.  

3) The pressure indicator of bottom hole can observe and control the well conditions easily.  

4) Close levers, convenient to operate.       

5) Compact size and light in weight are easy to set up and transport on working plains and mountain area.

B. Advantage

1----Forward,turn,and the impact of all the compressed air as power,structure simple,

power,relocation facilities.

2----In the single-top,double top,bearing-type three supporting structures to choose fom,can adapt to any geological features.

3----Centralized control mechanism,easy to operate.

4----Unique dual muffler,muffler effect, reducing environmental pollution
