borehole Drilling equipment

Our factory have produced rock blast hole crawler drilling rig for mining project over 20years.

Types of crawler DTH mining drilling rig
1,All pneumatic crawler DTH mining drilling rig
2,Hydraulic crawler DTH mining drilling rig

3,Integrated crawler DTH mining drilling rig

4,Truck mounted water well drilling rig
5,Crawler water well crawler DTH mining drilling rig

6,Diesel movable screw air compressor for crawler DTH mining drilling rig
7,Electric movable screw air compressor for crawler DTH mining drilling rig

1.Safe and stable traveling system of crawler DTH mining drilling rig

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 crawler DTH mining drilling rig

Drill carriage designed with advanced hydraulic system and completely functional gas circuit system.

3.Powerful feeding and rotating system of crawler DTH mining drilling rig

Promote reducer drives adopt turbine and worm, which have a big push-pull effort and can reliaze self-locking.

4.Adjustable boom of crawler DTH mining drilling rig

Adopt adjustable boom, the dip angle of hole and Level hole height can adjust by control the oil tank stretch out and draw back.

KG930A is one type machine improved from KY130 . It works in open air.

On KY130 base .KG930A optimize and upgrade the hydraumatic system , the part of drill boom and

part walking so on . It has better function than KY130 , for example : more motor , stronger

gradeability ,more reasonable drilling angle , faster rotation and propulsion speed and so on . Its

horse power life is longer and reliability is better .
