The tracks are mounted on the frame of the motor grader and are powered by the engine. The tracked motor grader is more suited to soft and uneven terrain than its wheeled counterpart. Tracks have a larger surface area and better weight distribution than wheels, which can reduce ground pressure and prevent soil compaction. The tracked motor grader provides better traction and stability, making it an ideal choice for demanding off-highway projects such as mining, forestry, and landfill construction.
The rear ripper grader (also known as the rear grader attachment) is an additional attachment to the rear of the motor grader. It is equipped with multiple tines or blades that can penetrate the ground and break up compacted soil. The rear ripper grader is often used in conjunction with the main grading blade of the motor grader. It is used to loosen compacted soil and provide additional fine grading and shaping capabilities. The rear ripper grader is commonly used in road construction, site preparation, and land leveling applications.
This type of grader can be used for grading, excavation, and other tasks. It is a versatile grader that can adapt to various working conditions and requirements. The multi-purpose grader is equipped with multiple interchangeable attachments, such as grading blades, rippers, and buckets. The attachments can be easily swapped out to suit different tasks, such as grading, soil loosening, and material handling. The multi-purpose grader offers flexibility and efficiency in various construction and maintenance projects.
Specifications of small motor graders:
Small motor graders usually use diesel engines to provide power. The power of the motor grader is expressed in horsepower (HP). The higher the horsepower, the stronger the grader's ability to cut and fill material.
The working device of the grader is a steel blade. The width of the blade affects the grading area and efficiency. The blade can be lifted, tilted, and rotated to achieve different grading, leveling, and excavation operations.
The transmission system of a grader typically includes a gearbox, a clutch, and a power take-off shaft. It can adjust the speed and direction of the grader to match different working requirements.
The operating system of a grader includes a steering wheel, pedals, joysticks, etc. By operating these components, the driver can control the movement and actions of the grader.
Most small motor graders use rubber tires as the walking mechanism, and some models use tracks. Tires or tracks can provide mobility and stability for the grader to adapt to different terrain.
Maintenance of small motor graders:
Check the motor grader for oil leaks, loose parts, and tire pressure. Ensure that the grader is in safe and good condition.
Regularly lubricate the grader's pivot points, blades, etc., to reduce friction and wear, and ensure smooth operation.
Regularly replace the fuel filter, air filter, and hydraulic oil filter of the grader to ensure the cleanliness of oil and air, and maintain the normal operation of the engine and hydraulic system.
Regularly check the blade for wear and damage, and promptly repair or replace it. Adjust the blade angle and height according to the working conditions to ensure efficient grading.
Regularly change the oil and filters of the engine, inspect the spark plugs, belts, and hoses. Perform regular inspections and maintenance of the engine to ensure its reliable performance.
Regularly check the brake system of the grader, including brake fluid, brake pads, etc. Ensure that the brake system is sensitive and reliable to ensure driving safety.
Check the battery and electrical connections of the grader regularly, ensure the electrical system is well-connected, and repair any damaged wires or connectors in time.
Provide the grader operator with regular training to improve their operation skills. Emphasize safety awareness and operational rules to reduce equipment wear and avoid accidents.
Small motor graders for sale are widely used in various industries and projects that require grading, leveling, and compacting of surfaces. The following are some common application scenarios for small motor graders.
Small motor graders are commonly used in road construction projects. They help to excavate, grade, and compact the roadbed, ensuring a strong and level foundation for asphalt or concrete pavements. The grader is also used to fine-tune the surface of the roads, ensuring proper drainage and a smooth driving surface.
In colder regions, small motor graders are used to clear snow from roads. Their blades can push snow to the sides, widening the road. They can also be used to cut through hard-packed snow and ice to expose the road surface below. In addition, the motor graders can be used to spread de-icing materials to improve traction and safety on the road.
Before the construction of buildings or infrastructure, small motor graders are used to prepare the site. The grader can be used to clear vegetation and debris, roughen the soil, and excavate and fill areas to achieve the desired site elevation and slope.
The motor grader can be used to spread gravel or crushed stone on roads, parking lots, or construction sites. The grader's blade and spreader attachments can evenly distribute the materials, compact them, and improve the surface's stability and traction.
In rural areas and construction sites, small motor graders are used to maintain dirt roads. They can be used to fill in potholes, smooth out washboard surfaces, and reshape the road as needed. Regular grading with a motor grader can help improve the drivability and safety of dirt roads.
Small motor graders can be used to create landscaping features such as grading lawns, sports fields, and golf courses. The grader can help achieve a smooth and even surface, adjust the slope, and improve drainage. In addition, the motor grader can also be used to create terraces and swales that help prevent soil erosion.
When looking for a small motor grader for sale, it is important to consider the main specifications of the machine. These include the engine size, weight, horsepower, dimensions, operating weight, and blade width. The engine size is very important because it determines the power of the grader.
