Description

Pneumatic roof bolter

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.



MQT series pneumatic roof bolters are working with our hexagonal drill rods of B19 and B22, wrench and various drill bits to carry out the roof supporting work.
