Advantages: 1. truly become rigs drilling machine and machine to achieve four interchangeable on the same track, peeling drill, DTH drilling, Y28 rock drill, Y45 rock drill 2. Our excavator digging machine transformation does not affect the function, do not go Second arm, easy to replace. 3. Increase the arm cylinder design, so that when digging machine stops at different slopes, can keep drilling vertical, the real effective blasting. 4. Use of imported automated hydraulic system, making drilling speed in the case of hard rock is slow, then fast in case of soft, soft landing of hydraulic drilling, drilling implement intelligent, reduce the failure rate of mechanical transmission. 5. We are digging machine without having to change the oil system, the use of hydraulic distribution the principle of the valve, so that the digging machine transformation quick and easy to change, fast access push to achieve the transformation scene, without the manufacturers. hole speed 20-25 m / h, punching range 80-160mm.
