SY870E

Cable Type

Electric Large Excavator

The system features a high-power permanent magnet synchronous motor that offers strong torque, stable output, and exceptional efficiency. Combined with an advanced electronic control system and independent cooling, it ensures reliable performance under both heavy and extended mining operations. SANY’s independently developed multi-pump hydraulic control system intelligently adjusts hydraulic flow and power distribution to maximize efficiency while reducing energy consumption. The machine’s heavy-duty chassis, reinforced structural components, and “four wheels and one track” layout deliver long-term durability with a design life of 20,000 hours, making it highly suitable for mining environments.
