The crawler type DTH drill rig is designed for uneven and complex working environments.
It provides:
- Strong stability
- Better climbing ability
- Easy movement on rough ground
- High adaptability in mining areas
This makes it ideal for quarry sites, mountain drilling, and remote construction projects.
3.Powerful Drilling Performance
Our down the hole drilling machine can achieve:
- Fast drilling speed
- Deep hole capability
- Stable operation under long working hours
- Reduced maintenance cost
It is widely used in mining blasting holes, tunnel construction, and foundation drilling.
4.Flexible Application Across Industries
The crawler DTH drilling rig is widely used in:
- Mining exploration and blasting drilling
- Quarry stone extraction
- Road and railway construction
