    Excellent Performance

    A diesel engine with turbocharger and fuel-feeding system of PT pump is adopted as the power supplier for the machine, with its characteristics of low fuel consumption, high power performance and large torque reserve.

    The diesel engine matches very well with the hydraulic torque converter and the transmission system, making a wide rotational speed range for machine traveling in high efficiency. Output power can be achieved perfectly, with the control of shifting on the transmission gearbox.   

    A hydraulic drive system is adopted for the working device, with its characteristics of simple structure, flexibility and reliability.

    The hydraulic-assisting mode is adopted in the control system, making the machine can be operated easily.

    A mode of hanging balance beam is adopted in the traveling system, making the machine works well in rugged areas.

    Centralized pressure-testing technology is applied for inspecting and debugging failure easily; the highly generalization of wearing parts makes it easier to maintain overall machine.

    The sound-proofing, heat-proofing and vibration-absorbing cab provides efficient operation space and excellent operation vision for the driver. The cab is also equipped with a comfortable adjustable driver’s seat  and  air conditioner , together with an optional  heater.

    Equipped with straight-tilting shovel as standard as well as U-shovel and angle shovel as options, all provided with well durable blade.

    Optionally equipped with the ripper, (3-tooth or 1-tooth available),u-shovel, angle blade, air conditioning , heater, rear ripper, ROPS frame, forest cabetc."
