Engineering Advantage Analysis

1. Golden Power Combination

• Changchai 390 Diesel Engine: Delivers a high power output of 29kW under 2600rpm high-speed operation.
• Italian Fomuu Hydraulic Pump: Flow rate error ≤2% (complies with ISO 4401 standard).
• American Parker Motor: Zero-speed braking torque ≥150N·m (ASTM D1557 certified).

2. High-Efficiency Compaction Performance

• 1200mm extra-wide steel drum increases single-pass compaction efficiency by 55%.
• 45kN vibration force ensures a compaction degree of ≥96% for gravel layers.
• Stepless speed regulation from 0 – 10km/h enables continuous operation on asphalt surfaces.

3. Ergonomic Design

• Yellow-Black body (RAL 1023 yellow + RAL 9005 black).
• Visual hydraulic monitoring with pressure fluctuation error ≤3%.
• Anti-slip steel pedal (meets ISO 286-2 safety standard).

Global Application Scenarios

Municipal Roads

• Final compaction of asphalt surfaces: The 45kN vibration force eliminates wheel marks.
• Precise rolling of sidewalks with 1200mm accurate coverage.

Agricultural Infrastructure

• Hardening of farmland tractor roads: The 3000kg self-weight prevents vehicle sinking.
• Embankment slope reinforcement: Hydraulic drive enables a 25° climbing ability.

Post-Disaster Reconstruction

• Foundation repair of collapsed road sections: 20 – 25cm layered compaction.
• Rapid construction of temporary runways: Stepless speed regulation from 0 – 10km/h.
