Product Description
Engineered with a robust 300kW diesel engine delivering peak torque at 1800 rpm, this 2021 Sany SY550H excavator represents precision-grade heavy machinery for demanding mining and infrastructure projects. Operating at 55 tons with a working weight of 51,000 kg, the unit combines power with exceptional stability through its optimized ground pressure of 87.1 kPa across 600mm track plates.
Hydraulic performance defines this model's capability. Maximum digging reach extends to 12,841mm with breaker attachment, while excavation depth reaches 8,077mm—specifications that translate to measurable productivity gains on large-scale earthmoving operations. The 3.1-3.5 m³ backhoe bucket handles substantial material volumes per cycle.
