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.

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%
