Mr. xx and Mr. Chen Ming with Japan’s made the acceptance assessment on our YGL-S100 Sonic Wave Drilling Rig on 6 June to 8 June 2012 at our company.

The Japanese experts undertook the no-load test and simulated load test, and

the key data of this sonic wave power head met the same level of their power head data at ex-works and the test result met Japanese company’s requirements. This not only shows the successful research and manufacture of sonic wave drilling rig and entering advanced level in drilling rig manufacture by Jinfan but also means Jinfan has filled in gaps in the drilling rig field in China.
