KG series semi-hydraulic open-air crawler rig
KG920B semi-hydraulic medium wind pressure open-air crawler drilling rig

KG920B type open-air drill rig on the basis of KY125 drilling rig, optimize and upgrade the hydraulic system, drill arm parts, walking components, Increase power (YC4D80) climbing ability is stronger, more reasonable drilling angle,faster rotation speed and advancing speed,longer motor service life,better reliability.

Improvement comparison
KG920B 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 330 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) improve50%
Fltting speed 450mm/s 336mm/s improve33%
