YT28 Air-leg rock drill is the most modern drilling machine products, it uses the design techniques of the modern rock drill, compared with the same type of product, with high efficiency, low noise, light weight, good economic effect, speed footage. Its superior performance, using the most reliable. The most efficient rock drill. It is most suitable for large-scale mining, medium-sized mining and tunnel drilling operations, the best response to domestic users, in the Korean market share has reached more than 70%. The linkage of gas and water, gas legs quickly returned, pressure regulator and other agencies. Control lever is concentrated with the handle body, the agency is new, easy to operate, equipped with a silencer cover can effectively reduce the noise and free to change the exhaust direction to improve the conditions of field operations. with the same type of rock drill: light weight, low noise, high efficiency, and economic effects. widely used in mining YT28 Air-leg rock drill, roadway excavation, and a variety of drilling operations. metallurgy, coal, railway, transport, water conservancy important equipment, infrastructure and defense in the rock engineering. the machine using the wet and medium hard or hard rock drilling operations, muzzle diameter of 34-42mm drilling depth of up to 5m. FT160A gas leg supporting drilling cutting of the horizontal and inclined blast holes; operations can also be installed with the trolley or stand.
