KG920B/KG920BH DTH Drilling Rig
Dia. Of Hole:φ90-115mm
Drilling depth:25m
Working pressure:1.0-1.7 Mpa
Air consumption:9-17 m³/min
Quantities can be customized
Advantage:
1.Safe and stable travelling system
With low gravity center and big ground clearance, this drill rig can easily travel on bumpy road.
It is driven by special wheel motor which brings strong grade-ability and low failure rate.
Special anti-lock device greatly improves the crawler drilling rig’s reliability.
Vehicle-mounted diesel engine provides strong power, so the crawler rock drill can freely travel without air compressor.
2. Powerful and reliable engine
Adopt famous 4-cylinder diesel engine as driving force which has advantages of large power, small volume, small vibration and reliable operation.
Adopt patent diesel engine air inlet regulating device (Patent No. : 200820087606.3) and desert air filter three-stage filter.
That strengthens the crawler rock drill’s adaptability to severe environment and lengthened the diesel engine’s service life.
3. Lastest designed Drilling Boom,Multi-angle operation
Optimally designed luffing mechanism and round drilling boom with the advantages of neoteric structure and easy maintenance greatly improves the drilling hole’s coverage area. That also makes low-order horizontal hole drilling available.
4. Powerful feed mechanism and rotating system
This rotating system is composed of orbit hydraulic motor and planetary gearbox. That provides the crawler rock drill, a type of wagon drill, with strong torque reserve and reduce the sticking drilling rate.
The feed mechanism driven by high power hydraulic motor can generate 20 KN lifting power. Adjust the pressure regulating valve on the control valve can get the favorable driving power which is required by the working condition.
Application areas:
Granite,Basalt ,Marble,Quartz or other rocks and stones.
