YN27C drills

YN27C YN27C rock drill internal combustion rock drill internal combustion rock drill YN27C single-cylinder internal combustion rock drill features 1, do not replace the head of the internal parts required simply moving the handle, it can work. 2. The machine is easy to use, more time, effort, with fast cutting speed, high efficiency. 3, it now stands at first-class level of similar products and similar products can and completely interchangeable parts. 4, perforated on the rock, vertically downward, horizontal up less than 45 ° vertically down the deepest drilling up to six meters. 85, the host weighing only 27 kg, easy to carry, suitable for mountains, no power, no air pressure device regions and greater mobility of temporary works particularly suitable. 6, both in the mountains, the plains, both in the heat of 40 ° or 40 ° below zero cold areas of work can be carried out, the machine has a wide range of adaptability. Uses YN27C type internal combustion rock mining machine with a punctured, cracked cement of various pops pavement, asphalt surfaces, broken, tamping, spade chisel and other functions, widely used in mining, road construction, quarrying, national defense projects and other technical parameters Weight : 27 kg Engine type: single cylinder air-cooled two-stroke gasoline engine carburetor type: No float Ignition: SCR non-contact system Engine displacement: 185 cm3 engine load speed (measured at the time of cutting the five-hole): ≥ 2450 r / min Rod idling speed: ≥200 r / min solder tail shank drill rod size: 22x108 mm hexagonal bore the deepest depth: ≥6 m Fuel tank capacity: ≥1.14 L Drilling speed: ≥250mm / min petrol and lubricants The mixing ratio (by volume) 9: 1 spark plug electrode gap: 0.5 ~ 0.7 mm fuel consumption (measured at the time of cutting the five-hole): ≤0.12L / M Impact energy: ≥20J
