Both bulldozers and motor graders are extremely adaptable construction machines. They can be used in the construction industry a lot of the time interchangeably. They are, however, built to do specific jobs better than the others. That’s why there’s a motor grader vs. dozer drama in the construction industry. If you must select between the two, you must first determine the most efficient for your project.
The first item to examine is the job requirements and equipment function. You should also be aware of the distinctions between the two types of equipment and their respective pros and disadvantages. We’ll compare motor graders and bulldozers in this post to help you make the best decision.
EQUIPMENT FOR BULLDOZER CONSTRUCTION
Bulldozers are massive machines that can move rocks, soil, demolition waste, and other materials. You can find them in quarries, farms, building sites, etc.
1. BULLDOZER COMPONENTS
Usually, the tractor is a track or crawler type mounted on metal treads in a bulldozer. Bulldozers can go across rough terrain like muddy or sandy areas without becoming trapped because they frequently employ tracks instead of wheels. In addition, the machine’s weight is distributed equally by the massive tracks, which allows it to go through a range of terrains. Finally, operators use the large, wide steel blade at the front of the machine for pushing, grading, or lifting. Here’s a quick rundown of the main components:
You can locate most of the controls in the operator’s cab, enclosed by a rollover protection structure (ROPS). The wide, side-mounted tracks provide plenty of room for operators to enter and exit the cab.
Track rollers, track assembly, and track frame: The track rollers, track assembly, and other mechanisms are all supported by the track frame. A continuous chain surrounds the track frame in the track assembly. The track rollers move on a flat surface created by the chains.
The bulldozer’s principal working tool is the blade.
It has a bottom cutting edge and corner bits to drift and cast material. The operators may manually or hydraulically position the blade depending on the mechanism. In various operations, the blade can be tilted, lifted, slanted, and pushed forward or backward.
The ripper is a claw-like device that attaches to the back of the machine. Operators hydraulically raise and lower the ripper to break up or loosen diverse materials like shale or asphalt. Use rippers to remove stones, stumps, and roots easily.
Push arms are mounted to the bottom of the blade, outside of the track frame, in most cases.
Pitch arms are diagonal units that run between the blade and the push arms and manage blade tilt and pitch and support the push arms.
2. BULLDOZER ATTACHMENTS OF VARIOUS TYPES
The ability to use a variety of attachments is one of the advantages of a bulldozer. Attachments give flexibility with only one machine and eliminate renting or buying additional equipment. Instead, rent the appropriate attachment for the job to save time and money. You can use the following attachments with a bulldozer:
- Straight blades are ideal for drifting materials across short or medium distances or for fine grading. There are no curves or side wings on this style of blade.
- Angle blade: An angle blade is a versatile instrument that can be used to side cast materials.
- U-blade: A U-blade is a type of blade that is used to transport big loads over great distances. It is taller than a straight blade and has a curved form.
- A box blade is used for grading and leveling large properties, parking lots, and highways. For best leveling performance, it may feature side cutters as well as front and rear moldboards.
- A winch is a cable or chain that is used to lift or move things, as well as uproot trees or stumps. It is attached to the back of a bulldozer.
3. BULLDOZER APPLICATIONS
Despite its large size, operating a bulldozer is relatively simple and suitable for novices. If a typical track dozer isn’t ideal for you or your staff, wheeled or micro dozers provide more agility in tighter locations.
A smaller bulldozer could be ideal for residential construction. Bulldozers are common in fulfilling these following tasks:
- Brush, trees, stones, and anything else that is embedded in the ground and in the path of a building project can be removed with bulldozers. They can also be used to remove wet topsoil in preparation for road building. When it comes to removing boulders and rocks, a tilted blade is a powerful tool.
- Drifting is when materials are pushed directly ahead of the dozer blade. You can dtermine the maximum operating distance by the capacity of the blade. The maximum drifting distance for a medium-sized bulldozer is normally 200 to 500 feet. Operators also use Bulldozers in transporting demolition waste.
- Dozers are excellent in spreading fill materials like rock or soil.
- Backfilling: Dozers are also good at backfilling holes or trenches. When using a bulldozer to backfill, the angle blade is the greatest instrument.
- After clearing or spreading debris, bulldozers are capable of fine grading and constructing drainage. When it comes to complete, however, they are not as exact as motor graders, as you will see.
- Bulldozers are handy for shallow digging during ditching.
- With a bulldozer, you may transport a variety of commodities across short distances.
The construction industry employs bulldozers in the following situations:
The following are some of the benefits of using a bulldozer:
- The tracks enable bulldozers to avoid sinking while crossing difficult terrain.
- Manual felling is more expensive than using a bulldozer to clear trees.
- Bulldozers are powerful and versatile machines.
- Bulldozers are less difficult to operate than other heavy machinery.
- They come in a variety of sizes to meet the needs of various projects.
- To improve operator safety and control, they frequently include comfortable cabs.
ADVANTAGES AND DISADVANTAGES OF USING A BULLDOZER
However, bulldozers are not perfect. As a result, if you require a machine that can do fine grading, a motor grader is likely the best option.
Another downside of bulldozers is that they can harm the environment. They may cause soil disturbance and erosion on sloping land, and the destruction of trees. According to one research, bulldozers, for example, damaged 33% of trees on steep terrain during forest road construction.
Bulldozers are also large machinery. Their weight compacts the soil, perhaps causing irrigation problems on shallow soils. Consider the impact and how it will affect your project goals in the long run before choosing a bulldozer.
A motor grader, also known as a grader or a road grader, is a thin multipurpose construction machine used to level a surface during grading projects. A motor grader’s general operating principle uses its moldboard or blade for rough or fine grading. The position and pitch of the moldboard, on the other hand, you can hydraulically adjust to fulfill a range of jobs.
Consider the motor grader when a job necessitates fine grading. Snow removal is also a breeze with motor graders. Many business owners place a high value on their motor graders. According to a poll, over 88 percent of engineers and equipment operations managers said they own the grader as the most critical piece of equipment. In addition, many people in the business choose graders because they keep roads in good shape and are valuable instruments for large projects.
1. MOTOR GRADER COMPONENTS
A motor grader is a massive machine with a distinctive form. Here are some of the essential elements:
You can find a motor grader’s multiple controls, levers, and steering wheel in the operator’s cab. A windshield and expansive windows enclose the cab.
–Moldboard: A grader’s working tool is the moldboard. It has a cutting edge attached to the bottom and end bits on the sides and is usually 12 or 14 feet long. Between the front and rear axles is the moldboard. It may be spun in either direction 360 degrees, allowing the operator to save time by using a process known as reverse grading. Moreover, the machine can also tilt it forward or backward and lower or lift it.
-The rubber-tired tractor positioned at the back serves as the prime mover. Diesel engine propell it.
-The grader’s frame connects to the front axle and runs the length of the machine. Its height gives the moldboard enough room to do its job.
–Scarifier: You can find the scarifier in front of or behind the front wheels. It breaks apart compacted surfaces using its teeth.
2. MOTOR GRADER ATTACHMENTS OF DIFFERENT KINDS
First, equip your motor grader with various blades and work tools, such as angle blades, box blades, and U-blades. Other regularly used accessories include:
- V-plow: A V-plow is a snowplow that attaches to the front of a motor grader’s frame. Its high “V” shape casts snow to both sides, making it perfect for deep snow removal. It’s for digging and carrying snow.
- Tire chains: In the winter, tire chains are frequently necessary to improve traction. You can find them on rear-drive tires and front-drive tires to help with front-end sliding.
- One-way snow plow is ideal for clearing snow and ice off roadways and city streets.
- Ripper attachment, like a bulldozer, is a claw-like unit that the mechanics install to the back of a motor grader and for breaking up asphalt, rocks, and other materials.
