Crawler Anchor Rod Drilling Machine is ideal for breaking through rock layers with a certain hardness coefficient, especially in the drilling of medium-hard and hard rocks. It uses a layered combination of drill bits for rotary drilling instead of impact drilling. The benefit of this approach is the standardization of borehole sizes, reducing wear on drill bits, and lowering the long-term maintenance costs of the drilling machine.
Product Features:
1. The design of the drilling machine is based on reliability, practicality, and portability.
2. The overall performance of the machine is stable, reliable, and has a long service life.
3. Most components of this machine are made of alloy steel materials to reduce weight while maintaining drilling capacity.
4. The machine has a modular structure that is easy to disassemble, facilitating quick and convenient relocation and installation, allowing for multi-hole construction in a single move.
5. Operators can work at a distance from the borehole, providing a good working environment and reducing labor intensity.
6. It is suitable for various construction techniques, including pneumatic down-the-hole hammer drilling, casing and core barrel drilling, and long spiral drill rod drilling.
7. Applications include construction in hydropower projects, railways, slopes for pre-stressed anchor holes, drainage holes, as well as landslide and rockfall disaster control projects.
