1.Rated torque:90/120/150(N.m), 2.Max output power:1.8/2.4/3.0(kW), 3.Weight:46/51/53(Kg) - details see: https://www.machineto.com/mqt-120-2-4-pneumatic-jumbolter-roof-bolter-coal-mine-drilling-rig-machine-10313119

Application

MQT-120/2.4 pneumatic jumbolter is widely used in roadway where the hardness of rock is less than or equal to f10, especially for rock bolting in roadway. It can not only drill roof rock bolt hole and anchor hole, but also stir and install resin cartridge type rock bolt and anchor without other equipments to install and screw down the rock bolt and nut once which achieve initial anchor pre-stressing force.
