A number of patented technology makes our products have many outstanding features: small original driving force, fast speed, stability control, low noise, simple, reliable, easy maintenance, flexible and mobile etc.
Our pneumatic rock drills could be divided into two parts, one is hand-held rock drill, the other is air-leg rock drill. Both of them have excellent drilling performance.
For hand-held rock drills, we have Y6, Y20, Y19A Y24 and Y26. Among them, the Y6, Y20 and Y24 are widely used in quarrying or construction industry.
A.Pneumatic rock drilling machine includes: Y6, Y20, Y24, and Y26(hand held), YT24 and YT28 (air leg).
This type rock drills use compressed air as power, mainly used in construction sites, various types of mines, tunnel, railways, water conservancy construction and national defense construction areas for drilling operations.
YT24 YT28 pusher leg rock drills always works with support air leg, can be used for any angle drilling.
Y6, Y20, Y24, and Y26 hand held rock drills works without air leg, mainly use for downwards drilling.
B. Gasoline rock drilling machine includes: YN27, YN27C and YN27J.
These types of rock drills adapt to outside situations where there is no water, no electronic power and no air compressor. It's a kind of hand held rock drill with gasoline engine, air pump and rotation plumbum equipment for running or stop. It can be used for breaking, drilling, blasting, tamping splitting and ramming.
YT28 Pusher Leg Rock Drill is a kind of high efficiency air leg rock drill machinery. It is mainly used for diging into mine laneway and blasting holes in all drilling works. It is indispensably importance machine tool in metallurgy, coal, railway, traffic, water conservancy construction and national defence stone project.
It is suitable for drilling and blasting under various of rocks at any direction angles. Blast hole dia is 34-42mm, drill hole depth is 5 m This machine may match with Model FT160BD short air leg or Model FT160BC long air leg.
