How much horsepower does the road roller have? This is a question that many people ask, but not many people know the answer to. A road roller is a construction vehicle used to compact soil and gravel, and it is also used to create a smooth surface for paving roads and highways. In this blog post, we’ll discuss the horsepower of a road roller and how it’s used in construction, so stay tuned!
What is a road roller and what can it be used for?
A road roller, also known as a steam roller or road roller, is a machine used to press asphalt or concrete. Road rollers are an important part of the paving process, they require a lot of horsepower to operate effectively, the horsepower required depends on the size and weight of the roller, and the type of material being compressed, they are often used on roads, high-speed During the laying of roads and other types of infrastructure.
How much horsepower does the roller have?
How much horsepower does the road roller have? The answer depends on the specific type of roller you are using, tire rollers usually have between 40 and 400 horsepower, while drum rollers usually have around 100 horsepower.
What are the different types of rollers on the market now?
The road roller belongs to the category of road equipment in the construction machinery. It is suitable for various compaction operations by the gravity of the machine itself, so that the rolled layer is deformed and compacted. It is widely used in high-grade highways, railways, airport runways, dams, Filling and compaction of large-scale engineering projects such as stadiums. There are different types of road rollers seen in life. There are two common ones, drum rollers and tire rollers. Many friends are puzzled by this. They are not all road rollers. Why are there so many differences? Today, I will explain the difference between steel wheel rollers and tire rollers in detail.
The difference in type
The roller structure of the drum roller includes smooth roller, groove roller and sheep foot roller. It is especially suitable for the compaction of asphalt pavements because of its concentrated force for compacting the protruding parts of the pavement. Smooth rolling is widely used, mainly for pavement surface layer compaction. According to the axle arrangement, there are single-axle single-wheel, double-axle double-wheel, double-axle three-wheel and three-axle three-wheel and so on. Generally speaking, it is mainly powered by an internal combustion engine and adopts mechanical transmission or hydraulic transmission. In order to improve steering and rolling performance, articulated steering structure and all-wheel drive should be adopted. In addition, its front and rear rollers are equipped with scrapers to remove the sticky substances on the rollers, and a water spray system is also installed to spray water on the rollers to prevent the asphalt mixture from adhering to the asphalt pavement.
The tire roller can adjust the ground contact pressure by increasing or decreasing the counterweight and tire air pressure, so as to adapt to the compaction of different materials. Pneumatic tires are used for the rollers, generally 3 to 5 front wheels and 4 to 6 rear wheels. This type of roller adopts hydraulic, hydraulic or mechanical transmission system, single-shaft or all-shaft drive. The compaction process has a kneading effect, is uniform and dense, has good maneuverability and fast running speed. It is because of this that it is often used for the compaction of engineering cushions such as roads and airports.
The difference in performance
Adopt articulated frame, hydraulic walking, hydraulic vibration, full hydraulic steering system. With two vibration frequencies and two levels of amplitude, it can be adapted to different thicknesses and compaction of various materials. The imported hydraulic pump, hydraulic motor and vibration bearing are used to ensure the reliability of the whole machine. The frame and hood are optimized for easy maintenance and repair. It has three-stage vibration reduction, and the cab adopts sealing and sound insulation measures to make driving more comfortable.
The ground contact pressure can be adjusted by increasing or decreasing the counterweight and tire pressure to adapt to the compaction of different materials. In addition to the vertical compaction force, the tire roller also has the horizontal compaction force. These horizontal compaction forces not only act on the direction of travel, but also act on the lateral direction of the machine. The achievable compactness is due to the ability of the compaction force to move the material particles in all directions. The action of these forces, combined with a “kneading action” created by the rubber tire, produces excellent compaction. .
The above is an introduction to the difference between a steel wheel roller and a tire roller. To sum up, in addition to the obvious differences in structure and configuration, tire rollers and drum rollers also have great differences in application fields and functional characteristics. The feet are long and short. Experienced construction The unit can configure reasonable roller equipment according to the needs of the project.
How to buy a road roller?
Road rollers are important equipment for asphalt driveways or parking lots. They are used to compact the asphalt, removing any bumps, which makes the surface smooth and level. If you’re in the market for a road roller, there are a few things you need to keep in mind. So we’ll discuss some of the things to look out for when shopping for a road roller and some tips on how to choose the one that’s right for your needs.
One of the most important things to consider when buying a road roller is weight, the heavier the machine, the more pressure it can put on the asphalt, which is important for getting a smooth, flat surface. However, you do not want to choose a machine that is too heavy, as this may damage the asphalt.
Another thing to keep in mind when choosing a roller is the size of the drum. The larger the roller, the more area it can cover in one pass. This is important for efficiency when rolling over large driveways or parking lots.
Finally, when buying a roller, you should also consider the price. Rollers can cost anywhere from a few hundred dollars to several thousand dollars, and it’s important to choose a machine that’s within your budget.

How to make sure the roller can work normally?
(1) The gearbox should be cleaned at least once a quarter. When cleaning, firstly in a hot state, stop and unscrew the oil drain plug on the side of the gearbox, release the lubricating oil in the box, then screw on the oil plug and pour the oil into the box. Kerosene, start the diesel engine, run the gearbox at low speed for 2-3 minutes, stop to drain the kerosene, clean the oil plug and screw it to the gearbox, then add new lubricating oil to the oil level to the mark line of the oil dipstick.
(2) The positioning devices of the speed change control mechanism and the reversing mechanism must be checked and adjusted frequently to keep the gears in the proper position to avoid dislocation accidents.
(3) Always pay attention to check the leakage of each seal of the gearbox, if the seal is damaged, replace it in time.
(4) Regularly check the connecting bolts between the gearbox and the frame, and tighten them if necessary, so as not to loosen and fall off.
Vibration wheel maintenance
The vibrating wheel is replaced with lubricating oil every 1000 hours. Check whether the vibrating wheel lubricating oil is leaking at any time; when checking the oil level, turn the oil filling port to the top, open the oil opening, and let the oil leak out until there is no leakage or less leakage. Replace the vibrating wheel lubricating oil during maintenance, and pay attention to cleaning when changing the oil.
Main clutch maintenance
(1) When the main clutch is engaged and disengaged, it should be smooth and gentle, and no excessive force should be used. When the clutch is engaged, the clutch pedal must be returned to its original position to fully engage the clutch. The clutch is completely disengaged. When operating, the clutch must be prevented from being in a half-clutch and half-engagement state to avoid burning the clutch.
(2) Check the main clutch frequently to avoid oil stains on the surface of the friction plate and pressure plate.
Cleaning, storage and transport of road rollers
(1) Cleaning of the roller
After each operation of the road roller, the dirt and dust on it must be washed off. At this time, special attention should be paid to the cleanliness of the diesel engine, generator, starter motor, fuel injection pump, fuel injector, hydraulic pump, etc., as well as the appearance of the hydraulic pipeline. , these areas must be wiped clean with a dry, soft cloth. If the road roller is parked for a long time, the water in the engine water tank must be released (in the cold weather in winter, it should be released after the work is completed every day). Carefully clean off the dirt and dust on the machine, scrub the outer surface of each part and all the lubrication holes with kerosene and apply grease once, and apply butter or anti-rust glue to the exposed parts that are not painted.
(2) Storage of rollers
The road roller should be stored in a dry warehouse. It is forbidden to store irrelevant items and gasoline. If it is parked in the open air in rainy days, the parking ground should be kept dry and it must be covered with a rain-proof cloth.
