Product introduction
Top hammer DTH drilling rig is designed according to the working conditions of small and medium-sized quarry and small open-pit mine, mainly used for hard and medium hard (F10 and above) rock drilling, can be used in quarry, civil engineering, road engineering open-pit mine and hydro-power station construction and other rock blasting drilling. The product is equipped with a high-efficiency hydraulic rock drill with fast drilling speed, low energy consumption, flexible mobility, strong climbing ability, and can be drilled on complex terrain.
Low operating costs
1. The high-power hydraulic rock drill with reverse drilling function minimizes the probability of sticking；
2. The intelligent identification of rock stratum attributes prevents sticking and idle drilling, extending the service life of drilling tools；
3. The reasonable power matching of rock dill-air compressor-engine further reduces fuel consumption；
4. Constant power control；
5. Self-adaptation of operation status.
