Firepower rammer petrol, diesel-efficient rammer, YCH80 rammer, YCH80 piston rammer, YCH80 small multi-angle rammer from corporate speaking, the coal industry, which is currently difficult to fire rammer coal companies themselves have their own sober thinking. First, the original pursuit of production speed, and now want to change the kind of thinking in the past. In the past are to benefit amount, efficient internal combustion type rammer now have to follow the market demand to organize production, restore market order to achieve a balance between supply and demand, curb rapid price decline, this may be the problem of the current coal companies should face together.

To market ability to sell a given operation, with the market able to contact some of the more closely, with some large customers to establish some long-term relationship. 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
