SD9 Specifications

SD9 dozer is elevated sprocket track typebulldozer with semi-rigid suspended, torque divider& power shift andhydraulic controlled. It boasts efficient torque divider, single lever operatedplanetary gear shift transmission and pilot boosted implement control system.The elevated sprocket and modular design promote the power system life andconvenience to maintenance and repair. The man-machine engineering controlsystem makes the dozer perform more easy, convenience and accurately. Theelectric monitored advanced ROPS is up to the international manufacturedstandard. SD9 dozer is applicable for earth-handling specialize in roadconstruction, desert, oil field, farmland, electrical power building, portsbuilding, mining and other engineering conditions.

    It can be equipped with Cummineselectrical monitored engine from USA. Integrated the electricalcontrolled fuel injection system and the air-air media cooling element, whichensures the exhaustion up to the Tier3 standard, and makes the fuel consumptionmore lower and power output more stronger.
