The SANY SY305H is a 30-ton class heavy-duty crawler excavator manufactured by SANY, a leading Chinese construction machinery producer. This model features a standard bucket capacity of 1.65-1.8 cubic meters with an operating weight of 31,500 kg. Powered by an Isuzu GH-6HK1 engine delivering 212 kW at 2,000 rpm with National IV emission compliance, it is designed for demanding mining and heavy construction applications with dimensions of 10,667×3,190×3,280 mm .
1.Powerful and Efficient PerformanceThe Isuzu GH-6HK1 6-cylinder engine generates 212 kW with 1,080 N·m torque at 1,500 rpm for heavy-duty mining operations. Its 7.79-liter displacement with variable geometry turbocharger delivers short response time and better plateau performance. The National IV emission compliant engine reduces fuel consumption by over 10% compared to previous models .
2.Advanced Intelligent Control SystemThe DOMCS dynamic optimized intelligent control system with positive flow technology improves efficiency by 8% and reduces fuel consumption by 10%. Real-time matching of engine output power to pump flow reduces energy loss and ensures immediate response. Multiple working modes allow operators to tailor machine performance to specific tasks for maximum productivity .
3.Durable Heavy-Duty StructureReinforced boom and arm with high-tensile steel withstand extreme stress of breaking rock and loading heavy ore. Heavy-duty undercarriage with wider tracks and heavier counterweights provides stability on uneven, rocky terrain. Anti-corrosion coating and independent extra-large radiator ensure durability and improved cooling performance in harsh environments .
This excavator excels in large-scale open-pit mining operations including overburden stripping, rock breaking, and heavy ore loading where 30-ton capacity is critical. It serves reliably in quarry aggregate production, major infrastructure development, and deep foundation excavation requiring high productivity. The SY305H is equally capable in building demolition, road construction, and material handling with various attachments available, making it a powerful solution for mining contractors and heavy construction fleets worldwide .
