Technical Description

The Kobelco SK135SR-2 is a versatile hydraulic excavator engineered for efficient digging and material handling in confined spaces. Powered by a four-cylinder D04FR engine with a displacement of 259.4 cubic inches (4.249 liters), it delivers a net power output of 92.8 hp (69 kW) at 2000 rpm. The hydraulic system features two variable displacement pumps plus one gear pump with a combined maximum flow capacity of 68.7 gallons per minute and a relief valve pressure of 4975 psi, enabling powerful, precise boom, arm, and bucket operations. The excavator’s maximum digging depth reaches 18.2 feet, with a maximum vertical wall digging depth of 16.1 feet, a maximum loading height of 22.2 feet, and a maximum reach along the ground of 26.9 feet, making it highly effective for a range of excavation tasks. Dimensionally, the SK135SR-2 features a shipping height of 9.3 feet, a length of 24.4 feet, a width across the tracks of 8.2 feet, and a ground clearance of 1.5 feet. The track length on the ground measures 9.5 feet, and the tail swing radius is a compact 4.9 feet, facilitating operation in tight jobsite environments. It rides on 19.7-inch shoes and reaches a maximum travel speed of 3.5 mph (5 kph). With an operating weight of approximately 30,424 lbs, it balances power and mobility effectively. The reference bucket capacity is 0.7 cubic yards, suitable for a range of digging and loading functions. Additional features include a robust undercarriage, advanced electronic controls for smooth combined operations, and compliance with relevant emission standards to reduce environmental impact. The machine’s compact swing radius, efficient hydraulic system, and reliable powertrain make the Kobelco SK135SR-2 a strong performer in mid-sized excavator applications.
