Product introduction

The MQT serial pneumatic rock drill can be used in mining the tunnel which is half coal and its hardness of f is under 8/9/10 and it is a combination of drilling, stirring and installing. The double exhaust and the latest sealing structure ensure the fast and free lift of the supporting leg which raises the working efficiency and the noise is reduced by the unique silence system. The  principal axis of the drilling machine and the center coincide to ensure the direction of drilling, which is designed to ensure the support.

The MOT-130/3.2 is the pneumatic rock drill of biggest torque and highest working rate in China. That serial of pneumatic rock drill can be used with the 19/22 six square drill pipe wrench and drills made by our company to carry our the supporting task.
