The SANY SY650HB is a 65-ton class heavy-duty crawler excavator manufactured by SANY, a leading Chinese construction machinery producer. This model features a standard bucket capacity of 3.5 cubic meters with an operating weight of 63,200 kg (65,000 kg for SY650HB-S version). Powered by an Isuzu 6WG1 engine delivering 345 kW at 1,800 rpm with National IV emission compliance, it is designed for demanding mining and heavy construction applications with dimensions of approximately 12,000×3,400×3,800 mm .
1.Powerful and Efficient PerformanceThe Isuzu 6WG1 6-cylinder engine generates 345 kW with 1,980 N·m torque at 1,500 rpm for heavy-duty mining operations. Its 15.681-liter displacement delivers low-speed high-torque characteristics with sufficient power reserve. The National IV emission compliant engine with DOC+DPF+SCR technology ensures clean operation and fuel economy .
2.Advanced Intelligent Control SystemThe full-electronic control hydraulic system with DOMCS dynamic optimization ensures precise and efficient operation. Kawasaki K7V280 high-flow main pump and KMX36NAE electro-hydraulic main valve deliver optimal matching output flow. The "positive flow" system enables each mode to work in the engine's best fuel consumption zone for high efficiency and low consumption .
3.Durable Heavy-Duty StructureReinforced work equipment with high-strength steel and wear-resistant plates ensures exceptional durability in mining environments. Three-stage box structure with widened sections and cast integrated connecting rods improve reliability and service life. The 20,000-hour working device technology extends maintenance intervals and reduces operating costs .
This excavator excels in large-scale open-pit mining operations including coal, iron ore, and hard rock excavation where 65-ton capacity and high durability are critical. It serves reliably in quarry aggregate production, port cargo handling, and major infrastructure development requiring continuous heavy-duty performance. The SY650HB is equally capable in building demolition, material handling, and specialized breaking operations with 210-215mm hammer attachments, making it a powerful solution for mining contractors and heavy construction fleets worldwide .
