Product Description
Designed for heavy-duty excavation projects, this 2020 Sany SY550H delivers 55-ton performance with exceptional operator control and jobsite stability. Powered by a robust 300 kW engine at 1800 rpm, this backhoe excavator tackles demanding terrain with a 70% climbing ability while maintaining precise handling through its 8 rpm rotation speed and dual travel speeds of 5.4/3.1 km/h.
Operators benefit from superior visibility in the spacious cabin positioned at 3470 mm, providing commanding sightlines across the 12,841 mm maximum digging radius. Ground-specific pressure of just 87.1 kPa ensures excellent stability on soft surfaces, while the 600 mm track plates and 4415 mm ground contact length distribute the 51,000 kg working weight efficiently. The 3765 mm rear turning radius enables confident maneuvering in confined spaces.
- Bucket capacity: 3.1-3.5 m³ for high-volume material handling
- Maximum digging depth: 8077 mm for deep excavation work
- 560 mm ground clearance for obstacle navigation
- Currently located in Hunan, China—ready for global shipment
