The MQT-130/2.8 series pneumatic anchor rod drilling rig is suitable for tunnels with rock hardness ≤ f10, especially for anchor rod support operations in coal tunnels. It can drill both roof anchor rod holes and anchor cable holes, as well as mix and install resin coated anchor rods and anchor cables. Without other equipment, the anchor rod nut can be installed and tightened in one go, meeting the requirements of initial anchor pre tightening force.

Small size, light weight, simple operation, and convenient maintenance.

Gear type pneumatic motor, stable operation and high reliability.

The fiberglass air leg design has high reliability and longer service life.
