The
roof bolter has light weight, simple operation and convenient maintenance. It is a commonly used pneumatic tool for injecting anchor cables and top anchor rods in coal mines. The gear-type pneumatic motor of the bolting machine has stable operation and high reliability. New FRP air leg design, safe explosion-proof and longer service life.
Roof bolter are also called anchoring rigs in some places, and they are drilling tools in coal mine roadway bolt support work. It has outstanding advantages in improving the supporting effect, reducing supporting costs, accelerating the speed of roadway formation, reducing auxiliary transportation volume, reducing labor intensity, and increasing the utilization rate of roadway section. The bolting rig is the key equipment for bolt support. It affects the quality of bolt support-the orientation, depth, and hole diameter accuracy of the bolt hole, as well as the bolt installation quality, as well as the personal safety and labor of the operator. Strength and working conditions, etc.
The roof bolter is mainly used for supporting and drilling of coal roads, rock road bolts and anchor cables with rock hardness ≤ f10, and can mix and install resin anchor rods and anchor cables. For anchor rods with damping nuts, it can be used for Tighten the nut directly at the time to realize the stirring and installation of the anchor rod at one time, and meet the requirements of the initial anchor pre-tightening force.
