YT29A is a heavy air leg rock drill .It is high efficient and low consumption.It’s widely used in railway,highway,hydropower construction and so on. It’s also the ideal substitute of the machines used in all kinds of drilling operations.
This drilling machine is suitable for working with the hard and solid rock to do the drilling level , inclined hole or the up drilling. The drilling diameter is commonly between 34 and 45 mm.The depth of drilling is 5m.According to the size of tunnel fracture surface and the operating condition ,it could be matched with the air leg,FT160A ,FT160C ,FT160 and FT170.To do the dry or wet drilling with the drill carriage and drilling rig is also feasible for YT29A .
The YT29A rock drill is the most strongest, powerful and highly efficient rock drill in the range.It gives improved productivity and drill steel economs and can be used on all rock formation and in all kinds of applications.
