YT28 type pneumatic rock drill, is a new type of high efficient drilling machinery. It is widely used in mine roadway drivage and various blasting hole drilling in the drilling operation, is metallurgy, coal, railway, traffic, water conservancy construction and national defense project of regarding the indispensable important equipment.
YT28 type drill wide use range, the most suitable for the hard or hard (f = 8 to 18) rock to drill horizontal and inclined hole, also can be vertical drilling on the roof bolt holes. Hole is 34 to 42 mm in diameter, and effective economic drilling depth of up to 5 m. Native roadway cross section can be according to the size and type FT160BD dispirited legs, long FT160BC type gas or gas FT160S type double leg supporting the use, also can work in a car or on the bench.
This machine is equipped with a transparent shell FY200B type oiler, easy to observe the oil level, adjust the volume of oil, to ensure good lubrication.
