Introduction
It is a kind of valveless high air pressure DTH hammer with foot valve.
The rock hammer has the fellow advantages
1: Valveless air distribution. more reliable.
2. The rock impacter are simple design of the piston, long life.
3. More efficient energy transfter,faster drilling speed, lower air consumption and lower oil consumption.
4. Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat
treated.
5. Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected multi-step
thread.
