1.Introduction of YT28 air leg rock drill
YT28 air leg rock drill is a high efficiency rock drilling machine. It is widely used in rock tunneling and drilling blastholes in various rock drilling operations. It is an important machine in stone works such as mining, railway, transportation and water conservancy construction.
YT28 air leg rock drill is used in a wide range of applications. It is suitable for drilling horizontal and inclined blastholes on medium-hard or hard (f=8~18) rocks, and can also drill the boltholes of the top plate vertically upwards. The diameter of the blast hole is generally 32-42 mm, and the effective economic drilling depth can reach 5 meters. This machine can be used with the FT160BD short air leg or FT160BC long air leg according to the section size of the roadway. It can also be installed on the drill or drill stand.
YT28 air leg rock drill is equipped with FY200B oiler with transparent casing, which is convenient for observing oil surface and adjusting oil quantity to ensure good lubrication.
