Ⅱ.Main equipment:

1. Power system: Equipped with Dongfeng Cummins C series Engine (110KW/2300rpm), dedicated for engineering machinery.

2, Main hydraulic system: adopts USA Sauer close-circuit pump and load-sensitive pump, cycloid motor from Eaton and hydraulic walking device from Korea Desung.

3. Main working equipment: adopts rack and pinion for push&pull, with efficient and stable transmission and convenient and simple maintenance. 

4. Chassis:  Equipped with high-intensity rubber track from home famous brand, less ground pressure ratio

5. Mud pump system:  Equipped with high quality mud pump(200L/min)

Ⅲ. Main Performance Characteristics 

1.Equipped with Dongfeng cummins C150 engine, large power, stable performance, lower fuel consumption, less   noise, more suitable working in urban area.

2. Driving head adopts cycloid motor from Eaton, which drives rotation directly, with large torsion, stable  performance, and two stall stepless speed regulation.

3.Driving head adopts cycloid motor from Eaton and load-sensitive variable plunger pump from American Sauer for push and pull , which has three stall speed and high construction speed of which leads far ahead in peers.

4.Main beam adopts self-patented technique-Slippage luffing mechanism. Not only with wider range of variable angle, but resolved the conundrum of unstable running of rig with auto-feed drill pipe box.

5.Ergonomic rotatable worktable, forward/backward moveable high quality seat with wide view range, comfortable and convenient operation.

6. Europe-American style surface, streamline sculpt and elegant appearance fully embody humanist designing idea.

7. The cover shell adopts overall backflip and air-spring assisted opening mechanism, with large open space and very convenient maintenance.

8.Advanced load-sensitive control, electro-hydraulic proportional control technics, imported international first-class hydraulic elements, independent radiation system, highly efficient productivity, reliable performance and energy saving.

9. Simple electric circuit design, low failure rate , convenient maintenance.

10.Walking system adopts imported motor and load-sensitive variable plunger pump, with wire-control, convenient and fast loading, unloading as well as construction site transition.

11.Equipped with φ60×3000mm drill rods, moderate machine size adapts to narrow and small working area and  high efficient construction as well.
