MQTB-70/1.7 Pneumatic Roof Bolter
MQT Series Pneumatic Roof Bolter always take a leading position in roof supporting industry in China, specially in following asp
In order to reduce the labor intensity and inprove working efficiency,we disigned MQTB penumatic
prop rib bolter on the base of our original protable 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 penumatic drilling machine,it has large torgue and power,and especially used for drilling hole in hard coal tunnel and coal-rock tunnel with strong hardness.
