YT29A Pusher Leg Rock Drill Machine ,
YT27 Pusher Leg Rock Drill Machine ,
YT28 Pusher Leg Rock Drill Machine
YT29A is a kind of heavy air leg rock drilling machinery, which is highly efficient with low consumption.
It is widely used in railway, highway, hydropower construction, etc., which also becomes the ideal substitute of the machines used in all kinds of drilling operations as well.
YT29A 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 34mm and 45 mm, and 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 , FT160B, FT160C and FT170.
Whether to do the dry or wet drilling with the drill carriage, drilling rig is feasible for YT29A.
