Description


1. according to China's mining conditions, to absorb the advanced technology of domestic and foreign impactor and design and manufacture of the latest products.


2. reasonable selection of materials, advanced manufacturing technology, quality assurance perfect.


3. has higher drilling speed.


4. can provide hardening treatment in order to prolong the service life and reduce the cost of use.


5. single impact power is large, and the power consumption of broken rock is low.


6. piston and bit weight to have the best momentum transfer.


7. the modern theory is adopted in the structural design, which makes the stress wave duration longer, the stress amplitude is lower, and the piston life is long.

 

Applications


Widely used in mines, quarries, earthworks and other engineering drilling blasting hole, guardrail hole,mountain reinforcement, anchorage and other engineering holes, geothermal exploration hole, Well bore and other fields.
