Pneumatic Prop Rib Bolter


MQTB-80/2.1 pneumatic prop rib bolter is designed for reducing labor intensity and improving working efficiency. This machine has such advantages: easy operation, stable action, and no anti-torque through prop supporting the body weight. Comparing with the portable pneumatic drilling machine, it has larger torque and power, and especially used for drilling hole in hard coal tunnel and coal-rock tunnel with strong hardness.
