The low-priced second-hand Shangpu SR2124S double-wheel roller is suitable for road construction operations

About Shangpu SR2124S double-wheel roller

Narrate

This partner, which has undergone nine years of engineering tests, has traveled across roads, municipal and infrastructure sites, always maintaining a solid 24-ton force to efficiently compact the roadbed. The dual steel wheels operate steadily and evenly, the hydraulic system responds sensitively, and the core components are well maintained. After the entire machine was refurbished, its performance became stable and reliable, and it was immediately deployed to the new battlefield, continuing to provide your construction team with solid quality and excellent value for money.

The essence of the refurbishment is respect, not embellishment. When the industry is accustomed to covering rusty frames with brand-new blue paint, we choose to define the refurbishment as a precise surgical operation. Your engineering team pointed out that there was a 0.3-millimeter gap in the steel wheel bearings? We only replaced that group of bearings instead of the entire transmission system; you planned to use this equipment for construction in the tropical rainforest? We strengthened the heat dissipation module while retaining the intact original hydraulic valve blocks. This restrained refurbishment based on the requirements of the working conditions extends the service life of each machine by five years!

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.
