◆YT28型气腿式凿岩机,是一种新型高效率的凿岩机械。它广泛应用于矿山巷道掘进及各种凿岩作业中钻凿爆破孔，是冶金、煤炭、铁路、交通、水利建设及国防石方工程不可缺少的重要机具。

◆YT28型凿岩机的使用范围较广，适用于在中硬或坚硬（f=8~18）岩石上钻凿水平和倾斜炮孔，也可垂直向上钻凿顶板上的锚杆孔。炮孔直径一般为34~42毫米，有效经济的钻孔深度可达5米。本机既可以根据巷道断面大小与FT160BD型短气腿、FT160BC型长气腿或FT160S型双级气腿配套使用，也可以装在钻车或钻架上工作。

◆本机配有透明壳体的FY200B型注油器，便于观察油面、调节油量，以保证良好的润滑。

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.
