YN27 internal combustion YN hand hammers impact hammers hammers YN27 small gasoline this year, China Coal Industry Association requested the United YN27 combustion type hammers. I will, in full play the role of market allocation of resources under the premise of promoting coal supply and demand relationship adjustment, which is the most important task of turning around the policy. Coordination of coal supply and demand relationship YN27 gasoline hammers, 2015 around four main areas of work to do. First, strictly control the illegal coal mine construction production impact hammers love road conditions, two are strictly control the production of coal mine unsafe behavior, three super-powers are strictly govern coal production, four are strictly control the production and consumption of low quality coal. 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 ° vertical 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. ?
