    KG series semi-hydraulic open-air crawler rig
    KG920A semi-hydraulic medium wind pressure open-air crawler drilling rig
    KG920A type open-air drill rig on the basis of KY125 drilling rig, optimize and upgrade the gas circuit system, hydraulic system, drill arm parts, walking components, climbing ability is stronger, more reasonable drilling Angle,faster rotation speed and advancing speed,longer motor service life,better reliability.

    Ground clearance 290mm Capacity 9-16m3/min 
    Improvement comparison 
      KG920A  KY125 Notes 
    Walking components motor+gear reducer structure Steel motor direct Reduce the motor pressure, improve motor lifetime 
    Walking  pressure 11MPa 14-16MPa 
    Drill arm components new drill arm   Horizontal, vertical hole at the same time;Horizontal hole height is low 
    Hydraulic system 30 pump; Drift diameter new valve group; New diverter valve, using new type of joint. 19.2pump Increasing traffic,reduce drag,neat appearance 
    Air course system 
    movable valve type shock valve 
    		spherical valve  well operation  
    Rotating speed 83r/min(diesel 1700r/min)
     107r/min(diesel 2200r/min)     		55r/min(1700r/min) improve 50% 
    Fltting speed 450mm/s  336mm/s  improve 33%
