Main Advantages:

1. Fully closed hammer housing(patent technology).

2. The ram can be superposed to obtain different energy pile hammer(patent technology).

3. The patent technology of superimposable ram can prolong the action time of striking energy.

4. High integrated hydraulic driving system.

5. Automatic plugging technology for high pressure pipeline pressure lose.   

6. Oil draining technology for pipeline, avoiding oil leakage and pollution when shifting to construction site.

7. Program control, striking energy can be set arbitrarily in nominal range.

8. Sensor technology, remote technology and man-machine
