MQTB-70/1.7 Pneumatic Prop Rib Bolter

MQTB-70/1.7 Pneumatic Prop Rib Bolter
Product Detailed

MQTB-70/1.7 Pneumatic Prop Rib Bolter is desighed for rig roof bolting, it is easy to operate and maintain.

In order to reduce labor intensity and improve working efficiency, we designed MQTB pneumatic prop rib bolter on the base of our original portable pneumatic drilling machine. 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.
