Firepower gasoline-efficient internal combustion rammer rammer rammer YCH80 YCH80 piston rammer YCH80 small multi-angle rammer China coal chemical industry met with US Daping coal gas project similar problems. YCH80 rammer as international oil prices plummeted, the downward trend in natural gas prices increased, the company's cash flow by the impact, while the cash flow is the key factor in determining whether the survival of the enterprise. High emission YCH80 rammer piston compared to the parties has been questioned before the high water and high coal consumption of the three issues, the drop in oil prices for coal chemical industry cash flow impact is more violent and direct, small-scale multi-angle rammer Meanwhile, high investment of coal chemical projects more heavy burden on corporate cash flow. I. Introduction: gasoline rammer, also known as fire ram, ram firepower blasting force in the combustible gas mixture with asphalt and gravel, concrete and compacted clay formation, especially for buildings, floors, courtyard, roadbed, bridges Pile, groove, wild, narrow space, such as the environment, to overcome the trouble to find the power cable electric rammer and no power can not work, especially to overcome the insecurity of personal electric rammer live working, capable and medium-sized mechanical construction tasks can not be completed. Second, the introduction parameters: motor gasoline, combustion air-cooled, single-cylinder, four-stroke power 4 / 5.5 HP tamping force 10KN jump height 40-65mm forward speed 10-13m / min tamping frequency 450-650 beats / min ram board size 300x310mm Weight 78kg
