This LIUGONG 620 is a pre-owned unit sourced from domestic construction fleet turnover. It has passed comprehensive inspection covering engine, hydraulic system, undercarriage, and cabin controls. Starts smoothly and operates without unusual noise or excessive smoke. Ready for immediate deployment.
The LIUGONG 620 is a 20 ton single drum vibratory roller that has established a solid reputation for reliable compaction performance in road construction, earthwork subgrade preparation, and site foundation compaction. Powered by the Dongfeng QSB6.7 engine producing 129 kW, this machine features dual amplitude settings (1.9 mm high / 0.95 mm low) allowing the operator to match compaction energy to material type and lift thickness for optimal density achievement with minimum passes.
The robust drum assembly with replaceable wear strips, reliable hydrostatic drive and vibration systems, and articulated frame steering provide consistent performance in demanding compaction applications. The operator station offers good comfort with air conditioning, adjustable seat, and clear visibility to the drum surface and edges. Well-placed service access points facilitate routine maintenance including engine oil, hydraulic filter, and vibration oil changes.
This LIUGONG 620 has been inspected with verified engine performance, hydraulic drive and vibration system operation, drum bearing condition assessment, and scraper mechanism function. The machine is ready for deployment on highway, municipal road, airport, and industrial site compaction projects. Parts availability for LIUGONG rollers is well-established through the manufacturer's global distribution network.
