KG910A Low wind pressure pneumatic crawler drill        Specification of pneumatic crawler drill              1.Powerful rotating system 2.Stable travelling system  3.Cummins engine 4.Blast hole machine 5.Rock hardness : f= 6-20    KG910A Low wind pressure pneumatic crawler drill   Low wind pressoure crawler drilling rig for blast hole drilling ; This machine for blast hole can used for Granite,Basalt ,Marble,Quartz or other rocks and stones.    Advantages of KG910A KG910A low wind pressure  pneumatic crawler drill   1. Safe and Stable Travelling System of KG910A low wind pressure  pneumatic crawler drill   This machine has low gravity center and big ground clearance, and can easily travel on bumpy road. It is driven by special wheel motor. That brings it 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 of KG910A low wind pressure   pneumatic crawler drill
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. New Drilling Boom of KG910A low wind pressure   pneumatic crawler drill   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 of KG910A low wind pressure  pneumatic crawler drill   The new 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 got the favorable driving power which is required by the working condition.                            Technical Details of pneumatic crawler drill
