Product detail

Motor grader

Introduction

Motor grader is one kind of earthmoving machine that uses a scraper to level the ground. The scraper is installed between the front and rear axle of the machine, and can rise and fall, tilt, turn and extend. The operation is flexible and accurate, easy to operate, and the site leveling has a high precision. It is suitable for building roadbed and road surface, building slope, excavating edge ditch, mixing road surface mixture, cleaning snow, pushing bulk material and maintenance of earth road and gravel road.

Motor grader

1. Sing-handle electro-hydraulic controlled power-shift T/M, 6 forward&3 reverse shifts makes operation easy and convenient

2. Hydraulic lock, auto lock/unlock NO-SPIN differential ensures stability

3. Powerful traction deal axle load allocation provides excellent stability while cutting hard surface

4. Serviceable, efficient hydraulic system enables every part to be fully used

5. Box-typed frame and advanced T/M enable it to complete heavy-duty work

6. A wide working range is accomplished through flexible blade suspension system and articulated frame

Features

  • Motor grader
    High Performance, Low Emission Engine

    The use of Cummins turbocharged engine enables the motor grader to achieve excellent productivity and low fuel consumption. The greater work speeds with high horsepower are provided thanks to the precise throttle control offered by the durable mechanical inline fuel injection system.

  • Motor grader
    Reliable Transmission with Proven Performance

    The operation is simple and convenient thanks to the single-handle electro-hydraulic controlled power-shift transmission with 6 forward and 3 reverse gears. Paired with ZF-technology power-shift transmission, the Cummins engine makes the motor grader more dependable and simple to use, and suitable for all kinds of working environments.

  • Motor grader
    Robust Chassis Frame

    Box-type chassis frame and advanced transmission allows it to execute heavy-duty tasks.

  • Motor grader
    Superior Stability

    Hydraulic lock and auto lock/unlock NO-SPIN differential ensure outstanding stability and powerful traction.

  • Motor grader
    Flexible Blade Mobility

    This motor grader has an extensive working range due to its flexible blade suspension system and articulated frame.

  • Motor grader
    High Durability, Precise Control

    The drawbar is constructed with A-shaped and U-shaped frame for high durability and precise blade control.

  • Motor grader
    Smooth Operation

    A turntable of four-inner gear guide type is included in the heat-treated rotating ring structure, which allows for smooth 360° rotation. The optimal curvature of the moldboard enables all types of soil to be moved freely and efficiently.

  • Motor grader
    Ideal Axle Load Allocation

    Axle loads are optimally allocated for superior stability and high work efficiency even when cutting hard surfaces.

  • Motor grader
    Reliable Hydraulics

    Every component can be fully leveraged because of the deployment of an efficient hydraulic system. Safety is ensured by a dependable hydraulic brake system.

  • Motor grader
    Excellent Visibility

    The spacious cab is designed with a side pillar layout for an excellent visibility that gives operator confidence to maneuver in various working conditions. The moldboard and front tires are clearly visible due to the well-positioned blade linkage.

  • Motor grader
    Work Tools and Attachments Front Dozer Blades

    The front dozer, or front blade, is a piece of motor grader attachments that is mounted in the front of the vehicle for spreading gravel piles, or pushing materials in corners where is difficult to reach with the moldboard.

  • Motor grader
    Work Tools and Attachments Rear Rippers & Mid-mount Scarifiers

    Attachments such as rippers and scarifiers are tools used for digging up asphalt, rocks or other hard materials that cannot be removed by the moldboard. The V-type scarifier can accommodate up to 11 teeth, the ripper also can accommodate 3-9 shanks.

  • Motor grader
    Automatic Leveling Device

    The automatic leveling device as a 2D machine control system enables precise height and slope control, giving a high flexibility in the selection of sensors and application fields.

  • Motor grader
    Rear Axle Drive System

    By using large-size rear drive axle, the reliability of the transmission is significantly improved.

  • Motor grader
    Double Row Roller Chain

    The double row roller chain has a greater tensile strength (26 tons) over peer and national standards.
