Braking systems used in small and medium-sized rollers under 10 tons

【文章概要】After all, small rollers weighing under 10 tons are classified as construction machinery, and they place stringent demands on braking performance; otherwise, during relocation or compaction on sloped surfaces, accidents can easily occur. Conventional braking systems can no longer meet the current needs of the small‑roller industry, making the adoption of automotive‑grade technologies with higher safety margins an emerging trend.

After all, small rollers weighing under 10 tons are classified as construction machinery, and they place stringent demands on braking systems; otherwise, during relocation or compaction on sloped surfaces, accidents can easily occur. Conventional braking systems can no longer meet the current needs of the small‑roller industry, making the adoption of automotive‑grade technologies with higher safety margins an emerging trend.

Depending on the compact roller’s weight and design, Luoyang roller manufacturers primarily employ air brakes, which offer responsive and practical braking, low maintenance costs, and a long service life.

The steady improvement in the technological sophistication of small and medium-sized road rollers is conducive to the healthy development of the domestic road‑roller industry, ensuring more reliable infrastructure projects in Southeast Asian and African countries. With the same budget, buyers can now access higher‑specification, more stable compaction equipment. Road roller manufacturers in Luoyang, together with their peers, have been working tirelessly to achieve this goal. As for the braking systems of small and medium‑sized road rollers…
The overall tuning is merely a microcosm of the current level of engineering machinery manufacturing; over the next 5 to 10 years, a series of technologically advanced road rollers will be launched one after another.

Small road rollers are pavement-compaction machines; to ensure their service life, regular maintenance of their components is essential. Below, the roller manufacturer outlines the maintenance procedures for the walk-behind roller’s transmission and hydraulic system.

I. Transmission Protection

The gearbox of a small road roller should be cleaned at least once every quarter. First, remove the oil plug on the rear of the gearbox, drain the internal lubricant, tighten the oil plug, and inject kerosene. Start the diesel engine, then engage the gearbox at low speed. After 3 minutes, stop the kerosene flow, remove the engine oil plug, and add fresh oil to the gearbox, topping up the engine oil level to the mark indicated on the dipstick.

Inspect and adjust the transmission and reverse‑positioning mechanisms to keep the gears securely in place and prevent unintended shutdowns. Regularly check the gearbox seals for leaks, and replace them if damaged. Ensure that the transmission and frame linkage bolts are always properly tightened.

II. Maintenance of the Hydraulic System

1. Inspect the filter, valves, pump, motor, cylinders, and other components for loose mounting bolts, and check each joint for oil leaks.

2. Check the oil level at the rear of the fuel tank. If the hydraulic oil is too low, add the same type of hydraulic oil.

3. Clean the hydraulic tank and change the hydraulic oil every six months. When refilling or changing the oil, be sure to avoid introducing contaminants into the tank. New oil or any other type of oil must be properly filtered beforehand.

Road Roller Manufacturer: The Lesser-Known Advantages of Small Road Rollers

1. It can access relatively narrow structures that are inaccessible to large road rollers.

2. Simple structure, compact footprint, and highly efficient in both use and storage.

3. Affordable small road rollers are inexpensive, practical, and cost-effective; their compact size makes them very popular with many users.

4. Exquisitely crafted, with a standard spray coating on the surface, it resists rust and boasts a long service life.

5. Easy maintenance: The overall compact design of the roller is relatively simple, making troubleshooting and routine maintenance straightforward.

6. Small road rollers are easy to operate. Being relatively lightweight, they can be operated conveniently by operators with the necessary knowledge.

Roller manufacturer’s recommendation: Operating guidelines for small rollers

1. In accordance with the product manual, routine maintenance requires frequent inspection of the connections and secure fastening of all components on the Luoyang road roller. Carefully verify that the vibration‑isolating pads are in their normal compressed state and check that the bearing bases are not loose. Replace any damaged parts promptly. During the hot summer months, temperatures can be extremely high; therefore, take precautions to prevent excessive heat from entering the machine’s interior. In addition to high ambient temperatures, summer weather often brings heavy rainfall and high humidity, so it is essential to maintain an appropriate operating temperature to avoid engine overheating.

2. Gradually transition from low-speed no-load operation to high-speed full-load operation. Regularly clean the handheld roller, removing mud and sand from its exterior, and wipe away dirt and grime from the engine and other components. Take care to prevent dust from entering the air filter. In addition, promptly check the engine’s oil, fuel, and other fluids, and replenish them to the specified levels as required.

3. The diesel engine of the small road roller should maintain a coolant temperature of 75–95°C. When the coolant temperature drops, open the radiator cap to release the coolant and open the drain valve on the cylinder block.
