Description
DTH drilling is a percussion system driving a piston inside hammer
body with up and down motion by compressed air and transmitting an
intensive percussion energy to the bit to enable the drilling by
crushing the rock. Drilling method by DTH hammer exerts high
drilling performance especially for drilling hard rock and
contributes for shortening work schedule. Hence, this method is
widely utilized for foundation work, landslide prevention work,
quarrying services, marine civil work, etc.
Advantages:
- Advanced hammer designs with high power and air efficiency
increases productivity
- Tailored product offering covers all your applications and
conditions
- Easy service and maintenance designs reduces machine downtime
- Generic and proprietary shank options give you flexibility and
reliability
