The integral hydraulic down-the-hole drill is widely used for blast hole drilling in open-air projects, such as metallurgy, mins, construction materials, railway, hydropower constructions, national defense constructions and earthworks. As one of most advanced integral hydraulic down-the-hole drill in domestic market, it is equipped with an efficient high pressure down-the-hole drilling system to facilitate the blast hole drilling with high precision and efficiency. Internationalized sourcing,  optimizing design of computer, power matching, development and application of load bearing system help to realize a full power matching of the power system from power to pump, and then to load bearing, which enables to reduce the energy consumption for the machine and ensure a best performance and a high reliability can be achieved
