Crawler Anchor Drilling Rig performs exceptionally well in rock strata with a certain hardness coefficient. It excels in medium to hard rock drilling by using a layered combination of drill bits for rotary penetration rather than impact penetration. This approach offers the advantage of standardizing borehole sizes, reducing drill bit wear, and lowering the long-term maintenance costs of the drilling rig.
Product Features:
1. The drilling rig is designed with principles of reliability, practicality, and portability.
2. The rig offers stable and reliable performance with a long service life.
3. To reduce weight, most components of this model are made from alloy steel materials while meeting drilling capabilities.
4. Its modular structure allows for easy disassembly, rapid relocation, and convenient installation, making it suitable for multi-hole construction in a single relocation.
5. Operators can work away from the borehole, providing a good working environment with low labor intensity.
6. It is suitable for various construction processes, including pneumatic DTH hammer drilling, casing and pipe drilling, and long spiral drill rod drilling.
7. Applications include construction of anchor holes for hydropower projects, railway and highway slope prestressing, drainage holes, landslide prevention, and rock collapse control projects.
