It is a kind of high air pressure DTH hammer without foot valve, and it is newest design. It is also one of the most advanced DTH hammers in the world. Urban high-rise building construction, high-speed rail, highways, bridges, subway construction, hydropower stations, nuclear power plant construction projects will involve the pile foundation project.

Bassed the characteristics of the wells,oil,gas and construction drilling,our company self-designed,developed and manufactured this kind of high pressure DTH hammer.

1.Using the latest rock drilling theory,optimizing the inside structure and the size of the air distrbution,to make the DTH hammer obtain the optimal energy transfer and make it achieve faster drilling speed and lower air consumption.
2.For such projects as the drill bit break,retrieving very difficult,we specially designed a safe and reliable anti-shedding
device for the bit.
3.The check valve can be replaced to replaced to the one with bigger air controlling hole to provide more efficient cutting
