Product Description
Built to endure the demands of large-scale earthmoving, this 2021 Sany SY550H stands as proof that Chinese engineering has matured into a global standard. Three years of field-proven performance back every weld, seal, and hydraulic line on this 55-ton workhorse — a machine designed not just to work, but to keep working.
Powered by a 300 kW engine at 1,800 rpm and carrying a 3.1–3.5 m³ backhoe bucket, the SY550H delivers the digging force and reach that heavy civil, mining, and infrastructure contractors depend on. A maximum digging depth of 8,077 mm and digging radius of 12,841 mm give operators the range to tackle deep foundations and wide excavation faces without repositioning.
