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;

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 floatable of the main axle can protect the rod thread and reduce the stress;

9,Comparing to the traditional hydraulic system, 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.
