Product Description
Built for operators who demand precision and endurance, the 2021 Sany SY375H is a 37-ton hydraulic excavator engineered to perform across demanding excavation and earthmoving applications. Powered by a 7.79L, 6-cylinder turbocharged water-cooled engine delivering 212 kW at 2,000 RPM and a peak torque of 1,080 N·m, this machine maintains consistent output through extended shifts. A reinforced cab structure with wide-angle visibility lines ensures operators maintain clear sightlines across the working envelope — critical when managing a maximum digging radius of 10,750 mm and digging depth of 7,155 mm.
- Working weight: 37,500 kg with a ground pressure of just 68.8 kPa for stable footing on varied terrain
- Bucket digging force: 235 kN; rod digging force: 210 kN for aggressive material penetration
- Bucket capacity: 1.7–2.4 m³ (standard 1.9 m³) to maximize cycle efficiency
- Climbing ability: 70% gradient capability for steep or uneven job sites
- Travel speed: 5.5 / 3.5 km/h dual-mode for flexible site repositioning
- Fuel tank: 540 L capacity supporting long operational intervals between refueling
- Currently located in Zhejiang, China — available for international export
