Product Introduction
MQT series pneumatic roof bolters are applicable to support with cable or bolt in coal laneway,half-coal laneway and rock laneway with rock hardness no more than 100MPa. They are combined with drilling,mixing and assembling. Dual exhaust model and new seals structure ensure the fast and smooth leg expansion and retraction. The unique silencer reduces noise,drilling shaft and leg center are perfect alignment,drilling stably.
Main Characteristics
1. Small volume, light weight, simple operation, convenient maintenance of gear type pneumatic motor, running stability, high reliability of new glass fiber reinforced plastic pneumatic design, safety explosion-proof longer service life. 2. Rock hardness f10 is mainly used in coal mine coal lane, rock bolt and anchor cable supporting drilling, and stirring and install the resin anchor rod, anchor rope, for with damping nut bolt, anchor drilling machine can be directly to tighten the nut when mixing, realize the bolt mixing, a complete installation, and meet the requirements of initial prestressing force anchor.
