590(D) crawler-type down-hole drill is an upgraded product of CM358A crawler-type down-hole drill,with more improved function and more reliable performance.
590 (D)internal combustion(JK590D electric)crawler-type hydraulic down-hole drill adopts diesel engine(electric motor)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 locating of hydraulic oil cylinder .Only when the JK590 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% to 50%,and the consumption of energy (fuel or electricity) is saved by 40% to 50% during operation.
The JK590 internal combustion(JK590 Electric)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.
