    Description of KG940A Crawler DTH DRILLING RIG :

     

    Powerful and reliable engine of KG940A Crawler DTH DRILLING RIG


    1. Adopt famous 4-cylinder
    diesel engine as driving force which has advantages of large power, small volume, small vibration and reliable operation.


    2. 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.


    New Drilling boom of KG940A Crawler DTH DRILLING RIG

     

    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.

     

    Powerful feed mechanism and rotating system of KG940A Crawler DTH DRILLING RIG

     

    1. The new rotating system is composed of orbit hydraulic motor and planetary gearbox. That provides the crawler rock drill with strong torque reserve and reduce the sticking drilling rate.
    2. 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.
