6.ISO9001:2008  7.ISO14000   2.Application of pneumatic drilling machine     
KW series water well drilling rig is a light, high efficiency, multifunction hewn hole drilling  equipment, it is widely used in industrial and agricultural water conservancy projects, such as drilling wells, testing wells or geothermal heating.  This drilling rig can work in different strata, the hole diameter can up to 300mm.   3.Advangtages of pneumatic drilling machine  
    
1.Safe and stable traveling system Low gravity, great ground clearance, make cars easily make drill through rugged road. The advanced automatic balance system, not only makes drilling stable, also greatly reduced the  impact of the car, and ensure the safe driving.   2.Centralized operating system of Mobile Drilling Rig   Drill carriage designed with advanced hydraulic system and completely functional gas circuit system.   3.Powerful feeding and rotating system of Mobile Drilling Rig  Promote reducer drives adopt turbine and worm, which have a big push-pull effort and can reliaze  self-locking.   4.Adjustable boom  Adopt adjustable boom, the dip angle of hole and Level hole height can adjust by control the oil  tank stretch out and draw back.   5.
