Tamping rammer road light engineering machinery hydraulic rammer rammer YCH85 four-stroke air-cooled gasoline rammer rammer YCH85 Walk-in terms of product categories or from the point of view of production capacity, YCH85 rammer China has become the world scale coal chemical industry largest country. But the size of the scale is not the same degree of industrial development, air-cooled four-stroke gasoline rammer on the whole, China's coal chemical industry is still in its infancy, there are still many problems to be solved. With the recent fall in international oil prices, China's coal chemical industry experienced a real shock. Gasoline rammer, also known as the fire ram, two-stroke internal combustion engine is made by principle, there is the inner cylinder, the next two pistons, piston internal combustion piston, the piston is under buffer piston. The lower part of the bottom of the cylinder kit tilt hammer, the cylinder axis vertical deflection forward. From the middle of the cylinder piston rod through hole extending cover under the rod protruding from the lower end of the cylinder, and one, between the cylinder and the hammer to hammer spring tension and linked into, and a handrail to control the ram forward direction earth machines.
