Easy ways to get the answers you need.overview
1. New cutting mechanism, truncated cone-shaped small diameter cutting head, strong rock breaking ability.
2. Narrow body modular design, body width 2.1 meters.
3. Spray and airborne fan double dust removal can effectively improve the dust removal effect and reduce dust pollution.
4. It adopts air-cooling and water-cooling for heat dissipation, which has good heat dissipation effect. The host can be moved over long distances without external water source.
5. The electrical system adopts internationally renowned brand components with advanced functions and high stability.
6. The hydraulic system adopts constant power, pressure cut-off, and load-sensitive control technologies to effectively extend the life of hydraulic components and reduce system failures. The main hydraulic components are all from internationally renowned brands.
