Engineering Advantage Analysis

1. Golden Power Combination

• Changchai 390 Diesel Engine: Delivers a high power output of 29kW, boosting efficiency in municipal projects by 40%.
• 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

• 1100mm extra-wide steel drum increases single-pass compaction efficiency by 50%.
• 40kN vibration force ensures a compaction degree of ≥95% for gravel layers.
• Hydraulic stepless speed regulation enables continuous operation from 0 – 10km/h.

3. Ergonomic Design

• Yellow-Black body (RAL 1023 yellow + RAL 9005 black).
• Visual hydraulic monitoring with pressure fluctuation error ≤3%.
• 180° rotatable control console allows for flexible steering in narrow areas.

Global Application Scenarios

Municipal Roads

• Layered compaction of asphalt surfaces: Achieves efficient operation at 10km/h.
• Precise rolling of sidewalks and bike lanes with 1100mm accurate control.

Agricultural Infrastructure

• Hardening of farmland tractor roads: The 2500kg self-weight prevents vehicle sinking.
• Embankment slope reinforcement: The 40kN vibration force prevents seepage.

Post-Disaster Reconstruction

• Foundation repair of collapsed road sections: Quickly compacts gravel layers.
• Emergency construction of temporary access roads: Zero-speed braking provides safety protection.
