Ⅱ.Main equipment:

1. Equipped with Dongfeng Cummins engine(179KW), dedicated for engineering machinery.

2. Push&pull and rotation system adopts open-circuit system: American Sauer load-sensitive variable plunger pump and American Sauer load-sensitive proportional multi-way valve.

3. Push&pull, clamp and walking mechanism are controlled by proportional multi-way valve imported from American Sauer Corp.

4. Push&pull adopts German reducer and radial plunger hydraulic motor from Sayi Corp.

5. Rotation system adopts Sauer close-circuit variable plunger pump and Huade electro-control dual speed variable plunger motor.

6. Main girder adopts four bar linkage luffing structure, which highly increases incidence angle range, insures the large angle and rig tracks not being off ground, having improved the safety performance.

7. Steel track plated with rubber can be loaded heavily and walk on all kinds of roads as well.

8. Wire-control walking system.

9. Load and unload drill pipe mechanism by overturning manipulator.

Ⅲ. Main Performance Characteristics 

1. Rotation adopts close-circuit system.

2. Rack and pinion for push&pull, with high efficiency, working stability..

3. Push&pull and clamp adopt auto-variable system, load-sensitive control.

4. Large torsion motor drives rotary mechanical manipulator for loading and unloading drill pipes, with adjustable overturning angle up to 220°. Rapid and convenient loading and unloading drill pipes largely reduces labor intensity and increases productivity.

5. Simple electric circuit, low failure rate. 

6. Wire-control walking system ensures safety during travelling.

7. Advanced hydraulic system raises 15-20% productivity than traditional one, reduces 50% heat and saves 15-20% energy.

8. Main parts are chosen from international first class producers, highly increasing products performance reliability.

9. Fit to two kinds of drill rod: Φ76×3000mm /φ89×4500mm.
