FEATURES
The YO29 is an newly-developed heavy-duty Pneumatic rock drill. It has optimized the cylinder diameter and the stroke, thus achieving high impact power and fast drilling. It is enhancing the percussion frequency and reducing the vibration to make the drilling work more stable. With good lubrication, the drilling work is high efficient and economical. It is an updated Jack-leg perforator ( Pusher-leg drifter ), ideal for drilling blasthole in the underground mining.
APPLICATIONS
YO29 Feeder-leg rock drill is suitable for making Horizontal / Slant blasting hole on the Hard / Medium-hard rock ( f=8~18 ). It has wide application in various industrial fields, e.g. Railway, Roadway, Water & Electricity construction, Civil engineering, Metallurgy, Coal & Metal mining, Tunnelling, Quarrying, etc.
