Description
1. Reasonable choice of materials, advanced manufacturing technology and perfect quality assurance.
2. Energy efficient, higher drilling speed.
3. Can provide hardening treatment to extend the service life and reduce the cost of use.
4. Single impact, broken stone's low power consumption.
5. The piston and weight have the best power transmission.
6. Structural design using modern theory, the stress wave longer duration, lower stress amplitude, longer piston life.
Applications
It is mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and so on.
