2‐ Structure Features：

1- Diesel engine-driving hydraulic system. Travel, rotate, feed, hoist, land, lift, unload, and so on all are run by Hydraulic components.

2-Working unit consists of feed system, slide guide(mast),top-driving rotary head, slide plate,centering apparatus, unloading system, hoisting system, etc.

3-Axial pressure, feed speed and rotation speed are adjustable.

4-Crawler self-driven structure travel mode, easy to move. Use crawler chassis. Steel track link(Inlaying rubber block is in option which is easy to travel on city streets)

5- During operation, four hydraulic landing legs will adjust the rig body level and stability

6- Four extra high landing legs are available, during long-distance transportation loaded with vehicle,it can be moved onto the vehicle directly and easy for transportation, no need to be loading or lifting.

7-Auxiliary hoist can list items within 1 ton (such as drilling tools, tools, etc), and also help to load or unload drill rod and drill tools.

8-The slide guide can be fixed with the body during operation in order to improve the operating stability of the mast.

9-Level instrument and dedicated centering apparatus ensure the perpendicularity and accuracy of the drilling hole.

10- Compressed-air system provides special oil mist lubricator to lubricate the impactor and longer the serving life of it.
