We have searched the manufacturing and production technology of key components. The important technical index of main product is equipped with good safety performance, are easy to operate and maintain. They are energy efficient equipments which are suitable for the mine work condition. The mountain jumbo which design for petroleum exploration we have produced, used by the customers, it is proved that the weight is light, the power is large, the drilling speed is one or double time higher and the energy consumption is 30% less than the dame series products both home and aborad. At present, the company is producing series of products with high-quality and perfect function such as hydraulic rock drill, fully hydraulic tunneling jumbo, fully hydraulic open-air drilling jumbo, anchor bolt jumbo, down hole hydraulic drilling jumbo, light-duty hydraulic engineering drilling rig. They are used for drilling blast holes in the rock, pile drivinghighwall grappling, geologic hazard governing, driving fire hole (glory hole) for steel making blast furnace, underground cable laying without excavating, petroleum exploration and so on. The hydraulic drilling equipment is mainly used for the earth advance and excavation engineering of access tunnel, intake tunnel, mining, underground cavity and so on. This type of equipment has the advantages that the control system is perfect, the automation degree is high, the technology is reliable, the whole machine is adaptable, it can serve energy source validly, it brings down the labor intensity, the rock penetration performance is high, and it is technology-intensive product. The equipment is used widely for such engineering construction as vehicular traffic energy source, mine, urban construction and so on.
