During maintenance, small rollers must be properly cared for, with frequent checks for any abnormalities in various components and meticulous management of the suspension system. So, how should the transmission of a small roller be maintained? Below, the roller manufacturer provides an overview.

Road Roller Manufacturer: How to Maintain the Transmission of a Luoyang Road Roller?

1. The roller manufacturer recommends cleaning the transmission at least once every quarter. During cleaning, first bring the machine to a warm operating state, then stop the engine, loosen the oil plug at one end of the transmission, drain the lubricating oil from the housing, and remove the drain plug. Next, fill the housing with kerosene, start the diesel engine, and run the transmission at low speed for 2–3 minutes. Finally, stop the engine, clean out the drain plug, and reinstall it in the transmission.

2. Gearbox 20 gear oil.

3. Regularly inspect and adjust the positioning devices of the gearshift and shifting mechanisms to ensure that the gears remain properly aligned, thereby preventing gear disengagement accidents.

4. The roller manufacturer recommends regularly inspecting all seals in the transmission for leaks and replacing any damaged seals promptly.

5. Regularly inspect the transmission and frame connection bolts, tightening them as necessary to prevent loosening.

The above outlines the maintenance procedures for small road roller gearboxes. Please save this information for reference in case of a malfunction.

Road roller manufacturer: What is the braking principle of a small road roller?

Brakes are not only capable of stopping bicycles, electric scooters, cars, and even road rollers in Luoyang; they can also handle the critical components of the braking system itself. So, do you understand how the brakes on a small road roller work? Now, let’s take a look at the braking mechanism of a compact road roller, as well as its smaller‑sized counterparts.

In the past, the braking systems of all mechanical drums remained at a very low standard, and malfunctioning brakes were a common problem.

To address this issue and enhance the operating and traveling performance of road rollers, our technical department drew on automotive braking systems and, taking full account of the road roller’s structural characteristics, implemented pneumatic brakes on compact models, thereby improving their overall performance.

The operating principle of the air‑brake system in typical small road rollers is as follows: when the brake pedal is depressed, the master cylinder valve— a one‑way valve that allows air to enter but not to flow back—opens. Compressed air then passes through this one‑way valve into the front‑brake booster and the rear‑brake spring cylinders, pushing the brake arms and rotating the brake cam. This action forces the brake shoes against the brake drums, engaging the brakes. Modern systems employ a dual‑circuit, cross‑linked braking pipeline configuration; if a leak occurs at any point, braking effectiveness is compromised.

Small and heavy-duty road rollers—this series of compact rollers is widely used. Featuring hydraulic drive and hydraulic vibration, along with hydraulic steering, they are ideal compaction equipment offering reliable performance and functionality.

Road Roller Manufacturer: Pros and Cons of Luoyang Road Rollers

First, we can examine the specifications of Luoyang road rollers. We can review their specific system parameters—for example, their vibration characteristics, the type of engine they use, and their compaction and climbing capabilities. Some manufacturers’ rollers encounter significant issues when operating on inclined surfaces; the hydraulic system and the engine are particularly critical.

Secondly, you can opt for small road rollers from reputable manufacturers, as they typically boast a strong technical team and an excellent reputation. Moreover, they offer a well‑established after-sales service that ensures continued support throughout the equipment’s lifecycle. For us, this kind of brand recognition serves as a reliable guarantee of quality.

In addition, when making your selection, you should also take after-sales service and maintenance into account to ensure that equipment malfunctions and other incidents can be resolved promptly.

Road roller manufacturers offer two main types: handheld double‑drum rollers and seat‑type rollers, with engines available in diesel or gasoline versions. Applications include urban and road surface maintenance, trench foundations, and pipe‑trench backfilling. Currently, domestically produced small rollers are categorized into handheld single‑drum models, also known as handheld road rollers, which are used for compaction tasks in construction projects and plaza‑level works, as well as for turf rolling.

Road roller manufacturer: What are the performance characteristics of a road roller?

After providing practical data on actual construction sites, the compaction technology exhibits the following performance characteristics:

1. The moisture requirements for the filler are broader.

Rollers have relatively broad requirements for the moisture content of fill materials, tolerating variations of 3% to 5% in either direction. In practice, these advantages become especially pronounced after compacting and leveling natural soils, particularly in arid or semi-arid regions. In such areas, natural soil moisture levels are very low—often close to 0% to 1%—so that a light surface spray of water is sufficient for impact‑type rollers to achieve compaction, significantly reducing the amount of water needed for compaction and lowering construction costs.

2. Large embankment thickness, large influence depth

The Luoyang road roller can directly compact the existing pavement (old roadway) and then compact the fill material, with each layer of fill measuring 0.6 to 1 meter or more in thickness. This approach can replace traditional excavation and layered compaction methods, thereby enhancing construction efficiency.

3. Fast compression speed and high efficiency

A small roller compactor achieves a compaction area per hour four times that of a conventional roller and a compaction volume eight times greater, enabling it to fully leverage its superior speed during paving operations in large‑scale workshops.

As outlined above, the road roller offers significant practical value. It is highly versatile, featuring easy adjustment and convenient operation. Through continuous improvements, it has become more aesthetically pleasing, with a coated surface that is both attractive and resistant to rust and corrosion.

Road Roller Manufacturer: Common Sense That Road Roller Operators Tend to Overlook

When operating a road roller, be sure to check the work area for debris to avoid unnecessary damage. Below, the road roller manufacturer shares some essential operating guidelines that drivers should know.

1. During operation, the roller’s drum must be started first to initiate vibration, and the internal‑combustion engine should be set to medium speed for adjustment.

2. The vertical grade of the work area shall not exceed the climbing capability of the left-hand-drive roller, and the transverse grade shall not exceed 20%.

3. When the seat‑changing roller is turned forward or backward, it must be done only after the roller has come to a complete stop; the exchange clutch shall not be used for braking.

4. The rolling and vibration frequencies shall be identical. For vibratory rollers with adjustable vibration frequencies, the frequency must be set prior to operation; adjustment of the vibration frequency is prohibited when the machine is not in operation.

5. The Luoyang road roller cannot engage vibration while traveling at high speed.

6. Do not compact the soil when its moisture content exceeds 30%; if the moisture content is below 5%, apply water as needed.

7. When the mobile site for a Luoyang road roller is located far away, it must be transported by truck or flatbed trailer; it shall not be towed by other vehicles.
