Title: Digging change DTH drilling Model: WJ-QK80 performance parameters: 1 For rock hardness:. F = 6-20 2. punctured range: 76-90mm 3. Promoting a stroke: 3.5m 4. punctured lowest level height : 250mm Product Description: 1 truly become rigs drilling machine, and achieve four machines are interchangeable on the same track, peeling rock drill drill ,, Y28, Y45 rock drill 2. Our excavator digging machine transformation does not affect the function, do not go to the second arm , easy to replace. 3. increase arm cylinder design, so that the digging machine stops at different slopes, can keep drilling vertical, the real effective blasting. 4. Use automation imported, so drilling on the rocks In case of the slow speed of the hard, soft case of the fast, to achieve a soft landing for hydraulic drilling, drilling implement intelligent, reducing the failure rate of mechanical transmission 5. digging machine without having to change our oil system, using the principle of the dispensing valve, so that digging machine transformation fast and easy to change, fast access push to achieve the transformation scene, no advantage to manufacturers of products and flexibility 1. 2. 3. Punch wide angle variation using a wide range, can play a variety of rock 4. punching speed Tel: 13544187954
