Features

New gas circuit, powerful efficient pneumatic motor and transmission motor cavity, more exquisite double gas circuit sliencer, these elaborate design make MQT - 130 reinforced pneumatic jumbolter have stronger torque and power than MQT – 120 and MQT-130. At the same time, it maintains the high speed as the former products. This type’s efficiency increased by 15% - 20% than other types under the same condition.
