    Cummins Engine
    The original Cummins high power, high torque and turbo-charging 4-cylinder direct injection engine guarantees the high reliability and durability. The air-air inter cooler system over the compressed air can enhance the oxygen content upon combustion markedly. The center fuel injection under high injection pressure allows the uniform atomizing of fuel, guarantees the normal combustion and reduces the exhaust emission. And the engine conforming to Euro ⅢA emission standard is optional.

    Filtering System
    The high efficiency dual element air filter ensures the quality of engine air intake. In addition, the air pre-filter can carry out the rough filtration over the air intake to enable the operation under the high dust concentration working conditions and prolong the maintenance interval of the air filter. The oil-water separator and two-stage fuel filter will filtrate the fuel many times to ensure the quality of fuel fed to the engine.

    Cooling System
    The parallel radiator makes cooling effect better and service easier.

    Maintenance and Service
    The easy maintenance of direct injection engine reduces the cost of maintenance. The global after service of engine enables the sharing of global resources. This will enhance the service efficiency, relieve the customers’ worry and ensure the attendance rate of excavator.

    Specialist of Engine Management

    Components Layout
    The special design of hydraulic system and components location can enhance the system efficiency of the machine. The hydraulic oil tank, main pump and main valve are arranged closely to shorten the connecting lines and consequently reduce the line friction and pressure drop. The radiator is arranged at the right side behind the cab to effectively reduce the noise, hot air and exhaust received by the operator.

    Pilot System
    The pilot pump is independent from main pump and supply oil to the pilot system which guarantee the stable and independent of pilot control and facilitate the maintenance.

    Monitor
    The multi-purpose true color monitor allows the real-time monitoring and display of machine state, engine speed, coolant temperature, oil pressure and fuel level etc.

    Power Control Mode
    3 power modes of heavy-duty power mode (H mode), saving power mode (S mode) and light-duty power mode (L mode) can switch at will to reduce the power loss. The combination of 3 modes can reduce the fuel consumption and better meet the different working conditions.

    Fault Auto Warning
    It allows the fault self-diagnosis auto warning display and fault message save up to 99,000 pieces approximately to facilitate the fault call and inquiry during the maintenance of equipment. There are 3 levels of warning display according to the fault severity.

    Engine Overheating Auto Protection
    The overheating protection will be active if the coolant temperature exceeds 102℃. Then the engine will not flameout while the system will reduce the engine speed. However, if the coolant temperature is too high, the operator should shut down the machine as required and find out the fault causes.

    Low Oil Pressure Protection
    When oil pressure below the standard value, the oil pressure switch will be closed, the text warning will display for 3s and then the engine will slow down to low idle speed. In such a case, the operator should shut down the machine as required to protect the machine.

    Maintenance Auto Remind
    The monitor will periodically remind the operator of changing the engine oil, grease and filter element at the set interval to support the routine service.

    Main frame
    The reasonable layout of robust main frame optimizes the utilization of steels.

    Undercarriage
    The X-shaped undercarriage with heavy-duty box structure is subjected to the repeated finite element analytical calculation and enhance the overall rigidity, strength and torsional resistance. Undercarriage is welded from the low alloy structural steel plates with overall process quality control. The critical welds are fully subjected to fault detection and stress test to ensure the product quality.

    Track
    There are ribs and crawler cradle in the middle of the track links. Using m-type seals to ensure the lubricating effect of the pin roll and pin bush.Extending the track working life effectively.

    Track rollers
    The reasonable arrangement of track rollers better distributes the stress applied to the track shoes.

    Carrier rollers
    Carrier rollers with reliable overall sealing property enables the long service life.

    Travel Device
    The drive unit employs the imported motors of high quality and the drive wheel adopts high frequency heating overall hardening process to enable the excellent wear resistance of the external gear rim.

    Idler Cushion
    The idler cushion with high quality sealing elements effectively guarantee the high pressure sealing inside the cylinder block, the springs are subjected to the special heat treatment to allow the excellent fatigue resistance.

    Cab Shock Absorption System
    The cab shell is installed to the platform through the cushioning materials consisting of the silicon oil and rubber to relieve the vibration, reduce the noise and guarantee the operation comfort.

    Cab External Structure
    The roof and both sides of cab are reinforced by the steel pipes to enhance the fatigue resistance and damping capacity. The falling object protection structure is bolted to the cab front directly to facilitate removal and consequently enable the machine to adapt to the working conditions and meet the specified safety requirements.

    Windows
    The glass is clung to the cab directly without frame to enlarge the visual field. The windows allow free adjustment to open/close the front and upper window and windshield,besides, the front glass can be set to the roof above the operator.

    Front Wiper
    The wiper located in front of cab pillar enlarges the operator’s field of view, it allows the continuous and intermittent operation modes.
