Understanding Motor Grader Basics

A motor grader is a construction equipment used generally for fine grading, leveling, and earthmoving. It comprises a long central blade that can be adjusted to create a flat surface. The machine excels at leveling roads, ditching, or slope creation. The right motor grader specifications can enhance your productivity and project completion.

Key Motor Grader Specifications You Should Know

1.  Engine Power (Horsepower)

• Why it Matters: The engine power is a very important factor that should be considered before buying a motor grader. The engine power is measured in horsepower (HP). The more the horsepower, the more the grader can handle rough surfaces and challenging conditions.
• Engine Power Range: 100 HP to 280+ HP.
• Examples: CAT 140 GC (196 HP), CASE 865B (220 HP), Mahindra G9075 (74 HP).

2.  Motor Grader Weight and Size

• Why it matters: Motor graders are among the heavy machinery. The weight of the machine helps to offer more stability on challenging surfaces. The weight of the machine makes this machine difficult to transport, so stronger transport equipment is required.
• Average operating weight: The weight ranges from 10,000 kg to 20,000+ kg
• Example: BEML BG605A weighs approximately 15,800 kg.

3.  Grader Blade Size

• Why it Matters: The central blade is an important attachment of a motor grader. It is used to grade the open area. The length and width of the blade are crucial because the area it will cover in one round depends on the blade size.
• Standard blade size: The standard blade size ranges from 10 ft to 14 ft.
• Example: Komatsu GD705-5 comes with a 14 ft blade.

4.  Hydraulic System in Motor Grader

• Advanced feature: The modern hydraulic system of the motor grader is equipped with load-sensing hydraulics for efficient operation.

5.  Articulated Motor Grader vs Rigid Frame

• Articulated Motor: Articulated motor has a hinged joint which allows better maneuverability and flexibility in rough and uneven terrain.
• Rigid Motor Grader: Rigid frame trucks are fixed on a single, fixed chassis, which makes them suitable for long-distance hauling but limits maneuverability. It works well on long-distance roads and can carry high-impact loads.

6.  Motor Grader Fuel Efficiency

• Motor graders are heavy machines and require a lot of fuel to operateLook for models with fuel-efficient engines to reduce operational costs
• Brands like LiuGong and CASE offer impressive mileage

7.  Motor Grader with GPS

• Why it matters: Modern motor graders are equipped with global standards technology such as GPS and telematics. These features enable accuracy and also reduce rework. Enhances accuracy and reduces rework
• Example: CAT motor graders come with integrated GPS and telematics systems.

Motor Grader Features and Functions

Different models come with different features. Understanding the features of a motor grader is very important because it will help you to ascertain the best machine for your requirements.

1.  Multi-Position Blade Control

• Allows the moldboard (grading blade) to be set at different angles and pitches.
• Helps carry out different grading tasks like leveling, ditching, or slope cutting with high precision.

2.  Automatic Leveling Systems

• Equipped with sensors and automated hydraulics to maintain a uniform grade across the surface.
• Minimizes manual errors and increases precision in grading, especially in long stretches.

3.  Comfortable Operator Cabin

• Advanced features like air conditioning, adjustable seating, and ergonomic control are present to make the operation comfortable during long working hours.
• It ensures operator comfort during extended hours and reduces fatigue to the operator.

4.  All-Wheel Drive (AWD)

• The all wheel drive of a motor grader enables good traction conntrol in rough and uneven soft grounds.
• It optimizes fuel consumption and also smoothes the way in challenging terrains.

5.  Rear Attachments (Rippers/Scarifiers)

• The rear attachments, like rippers or scarifiers, help loosen hard and compacted surfaces before grading operations.
• Extends the versatility of the grader for applications like road base preparation or demolition.

The above features make the motor grader an invincible machine for all types of grading and leveling operations. These features increase the productivity and operator’s comfort, which makes the motor graders an ideal machine for long-term use.

Choosing the Right Grader for Your Project

When you are looking for the perfect motor grader, it is very important to keep certain factors in mind. The right motor graders will provide you with maximum productivity with less cost.

Motor Grader for First-Time Buyers: Top Tips

When you are deciding on buying the right motor grader, certain factors should be kept in mind. For the new person who has entered the construction business, choosing the right motor grader can be difficult. Here we will discuss all the necessary factors that should be kept in mind if you are a first-time buyer.

1. Begin Small with Compact Models: If you are an entry-level business and have limited working capital, or you are working on a minor project, then a compact motor grader or an entry-level motor grader will be the best choice for you. They are easier to operate, less maintainable, and also cost-effective. They are great for lighter work and also pocket-friendly. Desi Machines is a trusted provider for top models from all popular brands.
2. Considering the Engine Specifications: The engine is the very heart of a grader; look for horsepower, fuel efficiency, and compliance with emissions. Check that the power rating is according to your working requirements. An overpowered machine may have run-down costs, while an underpowered machine may not perform the tasks assigned. Trustworthy brands, such as CAT,CASE, or Mahindra, usually provide a well-balanced engine specification for Indian conditions.
3. Warranties and Service Contracts: Check for models that have third-party assurance and service support that is easy to come by. With a good service contract, you would save a lot on time, money, and minimize hassle. Spare parts and service support in your area should always be assured.
4. Consider Rental Options: If the operation period is less, then you should consider renting instead of buying. Rental alternatives enable you to evaluate different models in real situations before purchase.
5. Always Test The Motor Grader: It is very much necessary to test the machine on the ground rather than looking at the brochure. Testing guarantees the comfort, safety, and productivity criteria of your own choice.

Cost Factors to Consider

When you are buying a motor grader, the cost of the motor grader exceeds the initial cost. There is a lot of cost that is incurred post-buying. We will discuss different cost factors which should kept in mind before buying.

1. Base Cost of the Machine: It is the one-time price of the machine. This one-time price depends on the brand, models, engine power, features, attachments, etc. Premium brands like CAT motor grader or CASE motor grader are costly but give better outputs.
2. Transport and Logistics: As these are heavy machines and require added transportation to carry these machines from one place to another, the transportation costs can sometimes be high. More heavier the machines, more the transportation cost of the motor grader.
3. Maintenance and Servicing: Periodic lubrication and servicing like oil change, replacement of parts, etc., as well as inspections, are important for operational efficacy and the longevity of the machine. Spare parts availability and prices, service stations, and technicians should be taken into account.
4. Operator’s Training: Proper training will ensure safe and efficient operations with less wear and tear. Some suppliers provide basic training, while sometimes you have to invest in the operator’s training.
5. Fuel efficiency: Fuel is the most important cost factor. Some models are fuel-efficient and give high productivity. You have to go through different models and identify the fuel-efficient models. If that is a challenging decision for you, then Desi Machines has experts who will help you to identify the best machine for your project.
