Crawler anchor drilling rigs are particularly well-suited for breaking through rock formations with a certain hardness coefficient. This is especially evident in their ability to penetrate moderately hard and hard rocks. The approach involves using a layered combination of drill bits for rotary penetration instead of employing impact drilling. The benefits of this approach include standardizing borehole sizes, reducing drill bit wear, and lowering long-term maintenance costs for the drilling rig.
Product Features:
1. The drilling rig is designed with reliability, practicality, and lightweight construction as its guiding principles.
2. The entire machine offers stable, reliable performance and has a long service life.
3. For the most part, this machine model uses alloy steel materials for components to minimize weight while meeting drilling capacity requirements.
4. Its modular structure allows for easy disassembly, rapid and convenient relocation and installation, making it possible to complete multi-hole construction in one move.
5. Operators can work at a distance from the borehole, providing a favorable working environment with reduced labor intensity.
6. It is suitable for various construction processes, including pneumatic down-the-hole hammer drilling, casing and rod follow-up drilling, and long spiral drill rod drilling.
7. It is applicable in projects such as hydropower station construction, railways, road slope prestressing anchor holes, drainage holes, landslide prevention, and rock collapse hazard mitigation projects.
