YN27 internal combustion YN hand hammers impact hammers YN27 gasoline YN portable rock drill hammers hammers splitting machines do a good job of ecological management. YN27 combustion type hammers accordance with the "balanced, focused, prevention, process control, comprehensive treatment" principle, the development of coal development and ecological management, impact crusher hand picks environmental standards and practices, establish and improve coal mining ecological compensation mechanism and a special gold, build a coal development "advance prevention, process control, after the disposal" of ecological and environmental protection defense, small gasoline hammers so that "getting old debts, do not owe the new account" to make significant improvement in mine ecological environment . YN27C hammers characteristics? 1, simply move the handle as required to complete the drilling or crushing operations. 2. The machine is easy to use, more saving time, effort, with fast cutting speed, high efficiency. 3, on the rocks perforated, vertically downwards, level up less than 45 ° vertically down the deepest drilling up to six meters. 4. Host weighs just 27 kg, only one person can work, easy to carry, suitable for mountains, no power, no pressure device regions and greater mobility of temporary works particularly suitable. Internal combustion hammers purposes: YN27C type internal combustion rock mining machine with perforated, various splitting construction, geological survey, concrete pavement, asphalt, etc., broken, tamping, spade chisel and other functions, is widely used in mining, road building , quarrying, construction, railway tamping, geological survey, defense works. ?
