In modern engineering construction, pneumatic DTH drilling machine is widely used in a variety of construction scenarios with its advantages of lightweight structure, flexible operation and low cost. Compared with the traditional crawler type drilling rig, the small pneumatic DTH drilling machine shows stronger adaptability and cost-effectiveness in specific environments.
Comparison with Crawler Drilling Rig
Item | Pneumatic DTH Drilling Machine (Small) | Crawler DTH Drilling Rig |
Power Type | Motor + Pneumatic (Hybrid) | Diesel + Hydraulic System |
Structure | Compact, Portable, Easy to Carry | Large, Strong Stability |
Application Scenarios | Narrow spaces, slopes, remote areas | Open fields, continuous operations |
Mobility | Manual transport or small pushcart | Self-propelled crawler movement |
Maintenance Cost | Low cost, universal parts | High cost, complex structure |
Price Range | Economical, ideal for SMEs | High cost, for large-scale projects |
Application areas of Pneumatic DTH Drilling Machine
This type of small DTH drilling machine is mainly used in the following projects:
- Slope support construction: Anchor drilling operations in mountainous areas, on both sides of highways or along railroads, the lightweight equipment can be more conveniently carried and positioned.
- Foundation pit reinforcement and support: urban underground construction site space is limited, small drilling rigs can flexibly enter the narrow area of operation.
- Mining and quarry blasting hole drilling: portable pneumatic submersible drilling rigs can quickly complete the deep hole blasting operations and improve blasting efficiency.
- Water conservancy projects and slope management: for complex terrain areas, such as riverbanks, mountain slopes, etc., small drilling rigs can be manually transported to the operating point.
- Geological exploration or farmland water drilling: lightweight, economical, able to drill deeper holes, is the ideal choice for agricultural well drilling.
It can be seen that small down the hole drilling rig is more suitable for small and medium-sized construction teams, complex terrain or limited budget construction needs. And although the crawler type down hole drilling rig is more powerful, it has higher requirements for terrain and budget.


Summarize the Advantages
- Easy transportation and handling: lightweight design, suitable for human operation;
- Economical and practical: low equipment cost and running cost;
- Simple structure and easy maintenance: suitable for long-term field operation;
- Flexible and versatile: the drill bit can be replaced and different lengths of drill pipes can be added according to different drilling needs.
Portable DTH drilling machine is a cost-effective choice for users who need to carry out drilling operations in complex terrain, remote mountainous areas or with limited funds.
