    Detailed

    XR280C is equipped with CAT336D chassis, featuring extra stability. The chassis structure is highly intensified, and it adopts heavy duty telescopic hydraulic track, which is convenient for transportation and has superior travel performance.
    It adopts C9 HHP 261KW@1800 RPM under EPA Tier III emission standards, which meets the emission requirements of European and North America countries.

    ·The oil cooler and radiator is collocated at the rear of inter-cooler with good cooling effect. The fan is powered by hydraulic motor, and the fan speed is controlled by the piston pump. It is more quiet and the noise level meets the requirements.

    ·The main winch adopts single layer steel rope for convenient operation, which prolongs the service life of steel rope.

    ·The hydraulic system adopt negative flow control in addition to the overall power control and the utmost power control, which improves the system efficiency, and makes full use of the engine power. The auxiliary system adopts load sensing control system, which achieves the optimum match between the output power and the work load and achieves the flow supply according to the demand and improves the drive efficiency to the maximum.

    ·The power head is operated by a pressurized hydraulic cylinder system, equipped with hydraulic motor for drilling, spring vibration absorption device on the top. It is equipped with drive bushings suitable for friction type of internal locked drill shaft, and also the guided bracket with bearing for the drill shaft. 

    ·Advanced intelligent control technologies like CANBUS and virtual instrument; high reliability control device and the color LCD display for convenient operation and easy inspection, which can directly display the verticality of mast and the bore depth and real time check the display record automatically; automatically record the troubles occurred during the operation; online adjustment and diagnosis on the input/output signals, as well as various kinds of alarming information on the limit position of drill mast, changing breadth, main/auxiliary winch, filters, and warnings on service and maintenance.
