Hydraulic excavator is an important working tool, which uses the pressure oil provided by the pump station of the excavator or loader to clean up the soil in the floating stones and rock crevice more effectively in the foundation function of the building. It with hydraulic excavator and other dynamic host, can be widely used in metallurgy, mining, railway, highway, construction, and other areas of the building, or process of hard objects such as rocks, reinforced concrete, cement road surface, old buildings such as mining, crushing, demolition operations, can also through the transformation of drill rod, used for riveting, derusting, vibrating, ramming, pile driving, such as specific operations, application is very extensive. With its advantages of safety and high efficiency, crushing hammer has been widely used in the secondary crushing of mining areas and has gradually replaced the secondary blasting to carry out bulk crushing. In mining operations, the application of hydraulic crushing hammer in some special restricted conditions presents unique advantages, especially in selective mining and non-blasting mining operations, which is a new mining method.
