Introduction:

HC725 series tracked DTH drill is a newly developed DTH drill. The product has excellent performance, flexible operation, complete functions, wider adaptability and higher cost performance.
This product can be widely used in open-pit mining, building foundation excavation, various engineering water conservancy, power plant, transportation and national defense construction.
 
Advantages of crawler diesel drill:
 
1. Low speed and high torque hydraulic motor drive rotary device output torque requires drilling operation.
2. The propulsion of the cylinder makes the propulsion more stable, and the failure rate is significantly lower than that of the motor.
3. Double filters can effectively ensure the intake safety of diesel engine and extend the service life of the engine.
4. Can monitor the hydraulic system pressure of drilling rig at any time, improve the pressure of drilling rig, and ensure the stable and efficient operation of drilling rig.
5. Adopt well-known brand multi-way control valve, superior performance, centralized handle and convenient operation.
6. Reliable tension device of crawler drill ensures reliability.
7. Establish lighting for night operation and maintain necessary conditions.
A rod bank for easy operation and protection of drill pipe.
