Product Description
Engineered with a Mitsubishi 6D34TL-20 engine delivering 114 kW at 2050 rpm, this 20-ton excavator represents Sany's commitment to hydraulic precision and operational reliability. The SY205C-8 operates with dual main pumps producing 2 × 210 l/min combined flow, supported by a 34.3 Mpa main overflow system that ensures consistent performance under demanding load conditions. With 138 kN bucket digging force and a maximum digging depth of 6,630 mm, this machine handles excavation tasks with measurable efficiency.
Core Technical Specifications:
- Operating weight: 20,300 kg with 0.83 m³ bucket capacity
- Maximum digging radius: 9,885 mm; maximum reach height: 9,305 mm
- Water-cooled engine with 70% (35°) climbing capability
- Ground pressure: 44.8 kPa across 600 mm track plates
- Travel speeds: 3.2/5.5 km/h for versatile job site mobility
