Features 1. truly become rigs drilling machine, and achieve four machine swap on the same track 2. Our transformation does not affect the digging machine digging machine function, do not go to the 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. 4. import of automated hydraulic system, so that the speed of the case of drilling in hard rock is slow, then fast in case of soft, to achieve a soft landing for 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 principles dispensing valve, allowing quick and easy change digging machine transformation, fast access Push achieve on-site reconstruction, without the manufacturers.
