The 3Y183J articulated three-drum static roller is a heavy-duty roller with a large unit linear load. It is mainly used for the compaction of pavement and foundation of gravel, crushed stone, asphalt concrete, coal slag, stone and other materials, which is the ideal compaction equipment for railway, highway, airport, port, dam and industrial construction site. Remarkable compacting performance Dual frequency and dual amplitude vibrating system and scientific and reasonable static linear load and excitation force ensure the effective compaction of different materials and layers with different thicknesses. Outstanding powertrain Hydraulic drive system Adopt the closed anti-slip hydraulic drive system composed by imported heavy-load variable pump and motor, ensuring the good driving performance and high gradeability. Reliable Electrical System The electrical system adopts imported water-proof, dust-proof, vibration-resistant electric connectors for increased reliability. Imported maintenance-free battery has high start-up current and good adaptability. Static linear load: 792(N/cm)
