Manufacturers supply dimensional hole drilled WJ-QK80 change hydraulic digging hole drilling

Features 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 transformation does not affect the digging machine digging machine function, do not go second arm, easy to replace. 3. Increase the arm cylinder design, so that the digging machine stopping at different slopes, can keep drilling vertical, the real effective blasting Automation 4. Using imported hydraulic system, making drilling speed on 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. digging machine without having to change our oil system, the use of hydraulic distribution valve principle, so that the digging machine transformation quick and easy to change, fast access push to achieve the transformation scene, no to the factory.
