Product Description
Engineered with a robust 300kW power plant delivering peak torque at 1800 rpm, this 2021 Sany SY550H excavator represents advanced heavy-duty performance for large-scale earthmoving operations. Operating at 55 tons with a 51,000 kg working weight, the machine combines substantial digging force with precise hydraulic control across a 12,841 mm maximum reach and 8,077 mm digging depth. The 3.1-3.5 m³ backhoe bucket capacity ensures high-volume material handling in mining, quarrying, and major construction projects.
Built on Sany's proven SY-H series platform, this model features:
- 8 rpm rotation speed with 3,765 mm rear turning radius for confined site maneuverability
- 87.1 kPa ground pressure distribution minimizing surface impact on sensitive terrain
- 70% gradeability and dual travel speeds (5.4/3.1 km/h) for versatile jobsite mobility
- 4,415 mm track ground contact length ensuring stability during maximum 12,279 mm reach operations
- 600 mm track plates across 2,740 mm gauge providing optimal weight distribution
Currently located in Linyi, Shandong, this China-manufactured excavator offers proven hydraulic architecture and structural integrity for demanding productio
