YX-420A/B/D Hydraulic Crawler Drill hole
    The drilling jumbo is a new improving type based on the original model ZGYX—2600、3500. according to the power it includes dual cylinder diesel engine2115 four cylinders diesel engine YD4D80, electric30w. except that ,it has two Specifications: Φ60 and Φ70.
    The characters of  drilling jumbo YX—410、420、430 is as follow: uses  the moving sub-head,and hydraulic power is provided by the two-pump. The hydraulic system keep stability and reduce the use of cost. uses chains to keep pushing,increaing the lifting force and lower the trouble
3.Increasing Strength of Bent Beams and Both steel guideways, wear-resisting material clips reduce the trouble.
4.electric drilling jumbo adds the Retractable cable device ,decrease the injure of the bad condition.
5.add compressed air system.of diesel engine.and decrease the trouble of diesel engine.
