4ton hydraulic road roller
The 4 Tons Full Hydraulic Roller, powered by a Changchai ZN490 diesel engine and backed by CE & ISO certifications, is an all-terrain compaction powerhouse. With a rated power of 29kW, it teams up with a Hansa hydraulic pump (flow error ≤3%) and a Parker motor (zero-speed braking torque ≥180N·m) for reliable performance. Its 1200mm-wide steel drum boosts single-pass compaction efficiency by 50%, while the 60kN vibration force ensures ≥96% gravel compaction. Hydraulic stepless speed regulation enhances complex terrain adaptability by 45%. Featuring an ergonomic yellow-black body, visual hydraulic monitoring, and a safety-certified anti-slip pedal, it excels in municipal road compaction, port foundation work, and post-disaster reconstruction, making it a versatile and efficient choice for various projects.

Engineering Advantage Analysis
1. Tripartite Alliance of Core Components
- CF186 Diesel Engine: Peak power of 6.6kW under 3600rpm high – speed operation
- Danfoss Hydraulic Pump: Flow rate error ≤3% (complies with ISO 4401 standard)
- Eaton Motor: Zero – speed braking torque ≥100N·m (ASTM D1557 certified)
2. Heavy – Duty Compaction Performance
- 900mm extra – wide steel drum (single – pass compaction efficiency increased by 80%)
- 25kN vibration force (compaction degree of gravel layer ≥96%)
- Hydraulic stepless speed regulation (continuous speed adjustment from 0 to 8km/h)
3. Ergonomic Design
- Yellow – black body (RAL 1023 yellow + RAL 9005 black)
- Visual dashboard (real – time monitoring of oil pressure, speed, and fuel level)
- Anti – slip steel pedal (meets ISO 286-2 safety standard)
Global Application Scenarios
Port Infrastructure
- Foundation compaction for container yards (900kg self – weight prevents settlement)
- Embankment slope reinforcement (hydraulic drive enables 25° climbing ability)
Expressways
- Final compaction of asphalt surfaces (25kN vibration force eliminates wheel marks)
- Expansion joint treatment (900mm precise coverage)
Industrial Plants
- Foundation strengthening of heavy – duty logistics passages (15-20cm layered compaction)
- Foundation compaction of loading platforms (rapid response with electric start)
