YT24 air-leg rock drill is a high-efficiency rock drill machinery. It is widely applied to rock drivage and drilling of blast hole in various rock drill operations and is an important tool in such stonework as mine, railway, transportation and water conservancy construction.
This rock drill has a wide application range and is mostly applicable to drilling horizontal or inclined blast holes on medium-hard or hard (f=8-18) rocks, with the drilling depth of 5m. This rock drill can be used with FT140BD short-air-leg or FT140B long-air-leg rock drill according to the size of the tunnel section and can be installed on a drill carriage or drill mounting for work.
In order to protect good lubrication, the rock drill is provided with FY200B oil lubricator.
