JGM757KN

  • Features

    Equipped with Weichai WP10 National III electronic-control high pressure common rail engine, it features low speed torque, energy saving and environmental protection.

    Highly efficient big capacity torque converter and highly reliable self-developed low revs transmission for outstanding comprehensive energy-saving effect.

    Double pump conflux, steering priority hydraulic system features high efficiency and low energy consumption.

    Full hydraulic coaxial flow steering amplification system enables light and flexible  steering, and reliable work.

    The hydraulic fuel tank uses high-precision paper filter element in the oil suction and oil return pipeline, which ensures the cleanliness of the hydraulic system.

    It improves the reliability of the hydraulic system by using hydraulic accessories of high standards and new technologies in the industry.

    The cooling system for the whole machine is optimized and the heat dissipation effect is good, ensuring the stability and reliability of the machine under harsh working conditions.

    The structural parts are subject to finite element analysis, and the key hinge joints adopt dustproof design, which ensures good lubrication of the pin shaft.

    The hinge joints are centrally arranged and the front and rear wheel tracks overlap, which improves the tire life.

    The working device can be automatically leveled, which contributes to reduced work cycle time and high efficiency.

    Heavy duty drive axle features high structural strength, great load bearing capacity, long life and high stability.

    The service brake adopts air-over-hydraulic caliper disc brake, and the parking brake adopts flexible shaft controlled caliper brake.

    Easy grease filling through using the lubrication hose at where it is difficult to access, which makes the service and maintenance more convenient.

    The large space panoramic cab features dustproof, shock absorption and noise reduction, which improves comfort and safety.

    Intelligent instruments system offers real time monitoring of the overall working conditions.

    Three power modes: “heavy load”, “medium load” and “light load” can be selected according to different working conditions to achieve fuel economy and consumption reduction.
