YT29A is a heavy air leg rock drill. It is high efficient and low in consumption. It’s widely used in railway, highway, hydropower construction and so on. It’s also the ideal substitute for 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 up drilling. The drilling diameter is commonly between 34 and 45 mm. The depth of drilling is 5m. According to the size of the 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.
Surface and underground rock drills, for light and heavy drilling jobs. From blast hole drilling to quarrying, anchor and wedge hole drilling, raise driving and bolting, these rock drills offer an excellent power-to-weight ratio and performance.
Features:
*Has the power-weight ratio.
*The shock absorber handle can reduce the recoil to the operator.
*Low noise, suitable for construction of urban road surface and pipeline network under the road surface.
*A variety of drill rods can be matched to adapt to breaking different materials.
