FEATURES
The YT27 is an advanced heavy-duty Air-leg rock drill (i.e. Perforator). With an enlarged cylinder diameter and corresponding optimized redesign, it works with more output energy, high impact power and fast drilling speed, while at lower air consumption. It can achieve an optimum matching of the impact energy and the percussion frequency, which reduces the vibration to make the operation more stable and comfortable. An improved superior lubrication system ensures a prolonged, endurable and trouble-free drilling work. It is an upgraded Pusher-leg rock drill, obtaining enhanced productivity, a most ideal mining tool for fast drilling blasthole.
APPLICATIONS
As the most robust, powerful and highly-efficient model among the whole range of Pusher-leg rock drill, YT29A is mostly suitable for making Horizontal or Oblique Blasting Bore on the Hard / Medium-hard rock ( f=8~18 ), also fit for drilling the Anchor Bolting Hole upward. Based on the Roadway-section size and operation conditions, it can be equipped with standard longer airleg or adjusted shorter airleg, also can be used with Multi-purpose Drilling Machine or Drilling Rig for dry/wet drilling. The YT29A is thus widely applied to Railway, Roadway, Water & Electricity construction, Civil engineering, Metallurgy, Coal & Metal mining, Tunnelling, Quarrying and other drilling work on various rock formations.
