神钢建机 SK 250

My Kobelco SK250-10 SuperX is a 25-ton-class medium-sized crawler excavator, perfect for mining, municipal construction, road construction, and foundation engineering, delivering outstanding performance, fuel efficiency, and reliability. It is equipped with a Hino JO5ETB-EDDK diesel engine, generating a rated power of 137kW (186PS) at 2100rpm, with a maximum torque of 654N·m at 1600rpm, complying with Tier 3 emission standards, ensuring powerful performance and low fuel consumption for long-term high-intensity operations. The Kawasaki dual-variable displacement axial piston pump hydraulic system with a main relief pressure of 37.8MPa provides stable and efficient power output, while the closed-loop hydraulic transmission enables smooth and precise operation. The machine offers a maximum digging force of 170kN and a bucket digging force of 142kN, along with a maximum digging depth of 6520mm (7000mm with long arm) and a maximum digging radius of 9890mm, meeting various construction needs. The SK250-10 features a spacious and quiet ROPS/FOPS-certified cab with an air-suspended seat, multi-functional color display, and ergonomic controls, minimizing operator fatigue. The reinforced heavy-duty chassis and 600mm wide track shoes ensure excellent stability and a low ground pressure of 55kPa, suitable for complex terrain. The centralized maintenance points, large-capacity fuel tank (403L), and hydraulic oil tank (273L) simplify maintenance and extend operation time. With a maximum travel speed of 6.1km/h (low speed 3.8km/h) and a swing speed of 10.8rpm, it balances operational efficiency and mobility in different job sites
