Our long-term and consistent strategy is based on the interaction between a number of strength factors. This includes advanced and customer focused research and development activities, highly value-added products, integrated manufacturing, direct sales to customers, effective logistics systems, financial strength and a strong corporate culture. Additionally, the significance of Rock mine as an advanced knowledge company is becoming increasingly apparent. Information technology is concentrated upon areas that enhance customer benefits, improve productivity and strengthen profitability.
Special properties have special design to improve its toughness and wear resistance.Basic and classic shape optimization, achieve the most obvious increase in toughness/wear resistance, increase the longer life.

These were our main considerations during the design and developmentprocess：
- Decrease air consumption, to reduce fuel costs.
- Increase the power level, for higher productivity.
- Optimize lubrication capabilities, to increase piston and hammer life.
- Improve the piston-bearing design, to reduce failures due to galling.
