Main Performance Characteristics:

1.The rotary and push and pull adopts closed-circuit, which can low down the temperature and reduce the near. Other assistant mechanical adopts open circuit driven by high pressure gear pump.

2.The Girder adopts four-connecting rod to increasing the range of the entry angle. Meanwhile, it makes sure of

the caterpillar landed on the ground when rig in big angle, which improves the safety;

3.Balance of the clamp makes sure of the concentricity and protection of the rod thread;

4.Cabin can automatically move up and rotate, which improves the view, with warm and cold air conditioner;

5.Transfer case made in German improves the Rotary and Push & Pull Speed;

6.The arrangements of oil pipes are reasonable and clear, the structure of the chassis is enhanced;

7.Safe wire -controlled walking system;

8.The floating of power head can effectively protect drilling pipe and screw thread for the convenience of moving drilling pipe up and down;

9.The advanced hydraulic system improve15-20% of the work efficiency, reduces 50% heat lost and saves 15-20% energy.;

10.Cooling system is equipped on the power head, which can protect the speed reducers and motors.

11.Unique design of the mechanical hand reduce the workforce and improve the work efficiency.
