Masters YT28 Air-leg rock drill give you one hundred assured ugly in downtown nobody asked the US in the mountains chasing someone. Masters YN28 internal combustion rock drill, although far in Jining, you can still find! For more information, please call ①⑤ zero ⑨②⑥⑥ ②⑨①①. YT28-type air-leg rock drill is a kind of high efficiency drilling machines. It is widely used in a variety of rock heading and blast hole drilling drilling operations are mining, railways, transportation, water conservancy project construction and other stonework important machine. YT28-type air-leg rock drill using a wider scope, applicable in hard or hard (f = 8 ~ 18) on a rock drilling horizontal and inclined blast holes, but also vertically upward to drill bolt holes in the roof. Blasthole diameter is generally 32-42 mm, drilling depth of up to 5 meters effective economy. The machine that can be based on the size of the roadway and gas FT160BD Short legs or FT160BC Long legs supporting the use of gas, the car can also be installed in the drill or drill frame work. YT28-type air-leg rock drill is equipped with a transparent shell FY200B type oiler, easy to observe the oil surface, regulate oil to ensure good lubrication.
