BasculerWhat Are the Main Types of Graders?
Motor graders come in two basic types: wheeled motor graders and tracked motor graders. Though both types essentially serve the same purpose, they differ in design and capabilities, making each suitable for different conditions while building and maintaining roads.
Wheeled Graders
Wheeled graders are the most common type of grader and are typically used in relatively flat areas. They have rubber tires, which make them highly mobile and fast. This type of grader is best on smooth, paved roads, urban roads, or highways where you need to level and grade quickly and efficiently.
Advantages of Wheeled Graders:
High mobility: Easy to move between projects and haul from one location to another, especially when traveling over paved roads.
Cost-effective: Typically less expensive to purchase and maintain compared to tracked graders.
Perform best on dry, firm ground: Works well in stable, dry conditions where you need precise grading.btnExit.
Best for:
- Building highways, extensive urban road networks.
- Regular maintenance of flat, well-maintained roads
Feature | Wheeled Grader |
Best Terrain | Flat, paved roads |
Speed | Fast, efficient |
Mobility | High |
Cost | Relatively low |
Tracked Graders
Tracked graders are used in road construction work instead of wheeled graders and are often used in areas that are less trafficked. These machines employ the same rear-engine, machine as a wheeled grader but have heavy-duty tracks that provide better traction and a larger footprint for weight distribution. These machines are used where traffic and terrain make the tracked machines more productive.
Advantages of Tracked Graders:
- Superior stability: The tracks keep the grader balanced easier than a wheeled machine on uneven or soft terrain.
- Heavy-duty performance: Tracks are usually associated with a heavier, more long-term piece of construction equipment.
- Better traction on rough surfaces: The tracks are wider and less likely to sink, making them perfect for maintaining a road in an area with poor soil or where erosion is prone to happen
Best for:
- Road maintenance in hilly, rocky, or unstable regions.
- Construction and grading of roads in harsh or remote environments.
Feature | Tracked Grader |
Best Terrain | Rough, uneven, hilly |
Speed | Moderate, slower |
Mobility | Low, less flexible |
Cost | Higher |
Key Factors to Consider When Choosing the Right Grader for Roadwork
Selecting the best grader for your road project requires a clear understanding of the terrain, the size of the project, and the specific demands of the job. Below are key factors that will guide your decision-making process.
Terrain Type
The type of terrain is the most significant factor in determining which type de niveleuse you need. Wheeled graders are designed for flat and stable surfaces, while tracked graders are built for rough, uneven terrain. Consider the following breakdown:
Terrain Type | Recommended Grader | Reason |
Flat, paved roads | Wheeled Grader | Faster and more efficient on solid ground. |
Hilly, rocky terrain | Tracked Grader | Tracks provide better traction and stability. |
Soft, muddy ground | Tracked Grader | Tracks spread weight evenly, preventing sinking. |
Project Size and Scope
For large-scale road construction projects, such as highways or expressways, a wheeled grader is often the preferred choice due to its speed and ability to cover large distances. Smaller, more localized road maintenance tasks in rugged terrain may require a tracked grader, which provides greater precision and stability in confined or challenging areas.
Project Size | Recommended Grader | Reason |
Large-scale roadwork | Wheeled Grader | Efficient for large, fast-moving projects. |
Maintenance of smaller, rough roads | Tracked Grader | Greater control and stability in tough environments. |
Precision and Speed
The grader tasks performed in the project will certainly influence your decision. If you’re doing high-speed grading over a large area, a wheeled grader is better. If you need more precise, detail grading in uneven or diverse terrain areas, the track grader is better.
Task Type | Recommended Grader | Reason |
High-speed road grading | Wheeled Grader | Speed is crucial for large-scale roadworks. |
Precise, fine grading | Tracked Grader | Better for precise leveling and drainage work. |
Why Choose a Wheeled Grader for Road Construction?
Wheeled graders are especially effective for building roadways, especially in big projects like highways or urban roadways that are generally flat and smooth. They provide the best speed, maneuverability, and efficiency for building roads when time is critical. Because they can cover vast areas very quickly, they help get work done before it’s needed, which is important if you must finish the job ahead of a big event where you can’t miss your time slot.
Extended Benefits of Wheeled Graders:
- Fast: They cover lots of ground quickly on smooth surfaces to help you get done in less time, which is super important for those times you have high-priority work that must be finished before a specific date.
- Cost-effective: When compared to a tracked grader, their initial purchase price is often a little less. Moreover, cost-of-ownership over the life of the machine is much less because they don’t get the wear and tear that tracked systems do on the hard surfaces, and they don’t experience the wear associated with a tracked system.
- Hard surface machines: These are perfect for dry, hard (paved), stable ground conditions. They really shine where soil stability is not an issue, and the surface is ready to grade.
- Fuel efficiency: For working on hard surfaces and pavement, they’re more fuel-efficient than a tracked machine. This is great for asphalt or any time you have to perform your work on a hard, dry surface.
Example
If you’re building a new highway or repaving downtown city streets, the wheeled grader wins because of the speed, mobility, and, ultimately, cost efficiency that allows you to finish the job on time and within your budget.
Type de projet | Recommended Grader | Reason |
Highway construction | Wheeled Grader | Speed and efficiency for large-scale projects. |
Urban road construction | Wheeled Grader | Ideal for flat, paved surfaces, and fast deployment. |
Large-scale resurfacing | Wheeled Grader | Greater mobility across vast, well-maintained road areas. |
Why Choose a Tracked Grader for Road Maintenance?
For tough grading jobs that involve controlling the slopes, however, a construction team will need to use a grader. However, for road maintenance, particularly in areas with challenging, uneven terrain or unstable materials like wet clay or soft sand, you want a tracked grader.
Why is that? Because tracked graders have tremendous stability, especially power and traction on tough surfaces. This makes them perfect for things like erosion control, maintaining mountain roads, or maintaining a road with bad foundation, and you need a machine that can maintain good traction on rock. Also, with tracked graders, that big package of all that weight, traction, and strength is supported by tracks instead of wheels.
Extended Benefits of Tracked Graders:
- Improved maneuverability: With the ability to pivot in place and move independently, tracked graders can navigate tight spaces and awkward angles more easily than wheeled graders. This makes them a better choice for road maintenance in urban or confined areas where space is limited.
- Less ground disturbance: The weight of the tracks is distributed over a larger surface area than tires, reducing the overall ground pressure. This means tracked graders are less likely to cause damage to sensitive or soft ground surfaces, making them ideal for work in environmentally sensitive areas.
- More stability on hills and slopes: Tracked graders have better traction and stability when working on steep inclines or uneven terrain. This makes them the preferred choice for road maintenance in hilly or mountainous areas.
Example
If you have to maintain roads in the mountains or fix roads that are washing out in a rural area, the tracked grader is the solution. It won’t slide around or have stability problems that make your situation worse.
Maintenance Task | Recommended Grader | Reason |
Mountain road maintenance | Tracked Grader | Stability and traction in hilly regions. |
Repairing erosion-prone roads | Tracked Grader | Superior control on uneven and shifting soils. |
Working on unpaved, soft roads | Tracked Grader | Tracks distribute weight more evenly on loose terrain. |
Key Features to Look for in a Grader for Road Construction and Maintenance
When choosing a grader, both wheeled and tracked models offer various features that can greatly impact performance. Here are the most important features you should look for to get the best grader for your road construction or maintenance needs.
Blade Design and Adjustability
A good grader blade is adjustable so you can change the attack angle for different tasks, from heavy, rough grading to delicate, fine surface leveling. A wider blade on wheeled graders allows them to cover a lot of ground quickly on large flat areas, like you find on a highway. Tracked graders often have more finely adjustable blades that are easier to control for extra precision when working on uneven ground – like repairing a wash-out on a gravel road that needs to be re-worked.
Horsepower and Engine Capacity
The horsepower of a grader directly impacts its ability to handle heavy-duty tasks. Tracked graders typically have more horsepower because they are built to handle the added weight and need for more traction when working in the rough stuff. Wheeled graders are generally built to have engines designed for smoother operations. These graders are built for faster grading, not for all the power needed to maintain traction when the going gets tough.
Operator Comfort and Safety Features
Because graders are often operated for long periods, operator comfort is essential. Look for things like ergonomic seats, climate control, great visibility, and adjustable steering. Many wheeled graders come with more advanced comfort features due to their use in long-duration, urban road construction projects. Tracked graders, designed to work in the rough stuff, may have comfort features that are less advanced, but are still comfortable, and the operator’s cabin is safe and secure for harsh duty.
