telescopic double cylinder diesel drill rig open - pit crawler type / downhole drills 10 - 17 bar
KG920B Geotechnical Drilling Rig Featurers:
1. Powerful and reliable engine
adopts double cylinder diesel as a driving force, traction power, climbing ability; The machine small vibration, work smoothly.To use the patent of diesel, intake adjusting device (patent Number : 200820087606.3) plus desert air filter level 3 filtering the combination of enhanced drill car to bad environment adaptability and prolong the service life of the diesel engine.
2. Adjustable boom
Adopt activity boom, through control the telescopic cylinders to adjust the angle and horizontal drilling holes height, expanding the drilling range, improved product flexibility.
3. Reliable hydraulic pump set
Using two separate gear pump oil, reliable, adaptable, and easy maintenance.· This machine adopt the gear transmission and soft features for connection ,so compact structure, smooth operation.
4. Reliable hydraulic system
Adopt special hydraulic components. That improves the system’s stability and reliability. Install oil liquid cooling device, to eliminate the exothermic hydraulic oil’s influence to the system

KG920B Geotechnical Drilling Rig in Factory
Powerful and Reliable Deisel Engine
1. The drilling rig machine adopt famous 2-cylinder diesel engine as driving force which has advantages
of large power, powerful grade-ability, small vibration and reliable operation.
2. The portable drilling rig adopt patent diesel engine air inlet regulating device (Patent No. : 200820087606.3) and desert air filter two-stage filter. That strengthens the crawler rock drill’s adaptability to severe environment and lengthened
the diesel engine’s service life.
Boom of the drilling rig is adjustable. The angle of drilling hole and height of horizontal hole can be
adjusted by controlling the stretch-out and draw-back of the hydro-cylinder. That enlarges the drilling
hole’s range and improve the machine’s adaptability.
Reliable Hydraulic Pump Set
1. Oil supplied by two independent gear pumps, reliable operation, strong adaptability, easy maintenance.
2. The drilling rig machine adopt gear transmission and soft connection, possessing compact structure and stable operation.
Reliable Hydraulic System
1. The mobile drilling rig adopt special hydraulic components. That improves the system’s stability and reliability.
2. Install oil liquid cooling device eliminatting the exothermic hydraulic oil’s influence on the system
