Product Description
Built for demanding operations, this 2016 Sany SY700C delivers 70-ton performance with operator-centric engineering. Powered by a 298kW turbocharged engine, this excavator combines robust digging force with refined handling characteristics. The 68,000 kg working weight provides exceptional stability across varied terrain, while the 3.5 m³ backhoe bucket tackles high-volume earthmoving with efficiency.
Operator comfort drives productivity on extended shifts. Standard cab design from this era prioritizes visibility across the 11,460 mm working radius, with strategically positioned glazing for monitoring bucket positioning and site surroundings. Hydraulic responsiveness benefits from dual 450 l/min pumps operating at 31.4 MPa, delivering smooth control during precision work. The 6.7 rpm rotation speed enables fluid positioning without compromising stability on the 600 mm track plates.
- Maximum digging depth: 7,210 mm for deep excavation work
- Bucket digging force: 350 kN with 300 kN rod force
- Ground pressure: 100 kPa minimizes surface disruption
- 70% climbing ability handles challenging gradients
- Currently located in Luzhou, Sichuan
