Product introduction
The MQTB-70/1.7 Leg Type to Help the Anchor Rod Drilling Machine can be used in drilling in the mining tunnel of half coal whose hardness is under 60MPa and it is a combination of drilling stirring and installing.It is high-rolling-speed, large-torque, easy-operating and convenient-fixing. Its weight is partly laid on the leg, so that the working strength is greatly deduced, it can be used to replace coal drill.
