Used DYNAPAC CA602 road roller

The Dynapac CA602 (including the CA602D smooth version and CA602PD bumped version) is a 19-ton heavy-duty single-drum vibratory roller, primarily designed for compacting ultra-thick rock/fill layers. It features strong vibration, high reliability, and versatility across various working conditions, making it a mainstay model for large-scale infrastructure projects.

I. Ultra-Thick Layer Compaction: Industry-Leading Capabilities

Rock Filling King: Capable of compacting 1.8-meter-thick layers, allowing for stones up to 1 meter in diameter, far exceeding ordinary 18-ton models.

Heavy-duty Steel Drum: Smooth steel drum with a 50mm thickened shell, impact-resistant and wear-resistant, significantly extending service life in rock conditions.

Maximum Vibration Force: 317kN (high amplitude) / 231kN (low amplitude), dual-frequency (29/31Hz) and dual-amplitude (1.8/1.1mm), ensuring stable deep compaction.

Static line load: 59.6 kg/cm², dual compaction by self-weight and vibration, one-time molding, reducing the number of passes.

II. Power and Hydraulics: Powerful, Efficient, and Fuel-Saving
Cummins QSB6.7 T3: 142kW (190hp) @ 2200rpm, turbocharged and intercooled, maintaining power even at high altitudes and under heavy loads.

Hydraulic Drive: Variable pump + variable motor, continuously variable transmission, strong traction, and no slippage.

Climbing Ability: Theoretically 49%, making mountain/steep slope construction easier.

Large Fuel Tank: 320L, continuous operation for 10–12 hours, reducing refueling time.

Fuel Consumption Control: Optimized power and hydraulic matching, overall fuel consumption is 10%–15% lower than competing products of the same tonnage.
