CM358A  drilling RIG

The CM358A is a crawler-type hydraulic down-hole drill, mainly used in drilling and blasting task, such as water and electricity project, exploitation of open mine, construction of roads and national defense engineering. CM358A crawler-type hydraulic down-hole drill adopts diesel engine and hydraulic oil pump unit as its drive device. The hydraulic motor is to achieve the supporting movements such  as turn around, propulsion, exaltation, moving and the swing angle location of hydraulic oil cylinder. Only when the CM358A is doing drill works, the down-hole impacter will exhaust compressed air. Compared with whole-pneumatic drills, the air displacement of matched air compressor is reduced by 30% to50%, and the consumption of energy (fuel or electricity) is saved by 40% to 50% during work.
