47.6kw Anti Jamming Jumbo Rock Drill Automatic Stop Of Impact At The End Point
KD12A-1BCD(L) Rock Drill Equipped With Functions Such As Automatic Stop Of Impact At The End Point, Automatic Anti Jamming Drill
Product Description:
KD12A-1BCD(L) Can meet all terrain working conditions within a slope of 14 °. Equipped with a high-power diesel engine, the transition speed can reach 5Km/h, achieving high-speed transition. The polar coordinate mechanical translation drilling arm structure with independent intellectual property rights accelerates the rapid positioning between each borehole, and there are no blind spots or dead corners on the entire working face. Suitable for alleyway operations in small mines.
Features:
The whole machine adopts full hydraulic drive, and the rock drilling speed can reach 0.8-2 meters per minute. The system is equipped with functions such as automatic stop of impact at the end point, automatic anti jamming drill, and induction of water slag discharge, which are easy to operate, safe and reliable.
The aircraft has a small body, compact structure, low center of gravity, flexible maneuverability, stable operation, and strong climbing ability. Using track walking, rock drilling can be carried out on a 14 ° inclined slope. The flexible hydraulic rock drilling mechanism can perform rock drilling operations on the working face, roof, side walls, and floor of the tunnel. This machine can not only drill and excavate blast holes, but also conveniently drill anchor holes according to the size of the section.
