About ShangTui SR20M

Narrate

The Shangpeng SR20M road roller is centered on an ultra-heavy mechanical vibration system, equipped with a dual vibration system, which provides efficient and uniform compaction capabilities for non-clayey soil and concrete materials. Its power system adopts a highly reliable configuration, with balanced fuel economy and performance, and is suitable for high-intensity working environments. The vibration wheel structure has been optimized, combining excitation force and durability, ensuring stable long-term output in large-scale infrastructure projects. From highways to mines, from dams to industrial sites, it interprets the industrial aesthetics of "functionality and cost-effectiveness" with its solid operational performance.

In the field of second-hand equipment exports, we always engrave "quality" into the genes of every choice and service. Every piece of equipment we select undergoes strict testing and in-depth maintenance to ensure that it remains stable in performance and durability when delivered to you - compared to short-term price fluctuations, what we care more about is your peace of mind when using it: reducing the loss from equipment failures and lowering the cost of subsequent maintenance. These "long-term values" hidden in quality are the most solid foundation for cooperation.

Daily Maintenance Checklist for Road Roller

1. Check Fluid Levels & Fuel

Inspect engine oil, hydraulic oil, transmission oil, and coolant levels (using dipstick or sight glass); fuel tank level. In hot weather (like current summer), coolant inspection is particularly critical to prevent engine overheating and shutdown.

2. Inspect Filters & Air Intake System

Check the cleanliness of air filter, fuel filter, and hydraulic oil filter; inspect air intake system for blockages. Lightly tap the air filter to remove dust (replace if severely dirty); ensure the filter element is undamaged. This step prevents contaminants from entering the engine, reducing 80% of early wear risk. At dusty construction sites (e.g., roadwork), daily air filter cleaning significantly enhances equipment efficiency.

3. Inspect Ground Contact Components & Brakes

Check tire/steel wheel pressure and wear (using tire pressure gauge); brake fluid level and braking performance (test by pedal depression); tightness of steel wheel or tire bolts. Daily inspections identify potential issues (e.g., loose bolts), preventing downtime repair costs.

4. Clean Machine & Check Fasteners

Remove mud, asphalt residue, and water stains from the roller’s surface; inspect critical fasteners (e.g., engine mounts, roller connection bolts). Clean with a soft brush or low-pressure water jet to avoid damaging electrical components. Post-cleaning, a tidy appearance improves heat dissipation. During rainy seasons, cleaning prevents corrosion, extending equipment life by 5+ years.

5. Operational Test

Start the equipment; check dashboard indicators (e.g., oil pressure, battery voltage); listen for abnormal noises/vibrations; test steering and compaction functions. Limit runtime to 2–3 minutes; stop immediately for troubleshooting if warning lights activate. Daily tests enable early fault detection (e.g., hydraulic system noise), reducing 30% of unexpected repair costs.
