Technical Description
The Kobelco 80CS is a mid-size hydraulic excavator designed for versatile earthmoving tasks, with an operating weight of 17,600 lbs and powered by a 54 hp (40 kW) four-cylinder A-4JB1 engine delivering net power at 2100 rpm. It features two boom/stick configurations: Option 1 provides a maximum cutting height of 22.3 ft, a maximum digging depth of 14.4 ft, and a reach along the ground of 23 ft; Option 2 extends these capacities with a maximum cutting height of 24.1 ft, digging depth of 15.3 ft, and 25 ft reach, enabling greater operational flexibility. The excavator supports bucket capacities ranging from 0.3 to 0.6 cubic yards, with a reference bucket size of 0.4 cubic yards, facilitating efficient material handling.
Dimensionally, the unit’s height to the top of the cab and shipping height are both 8.6 ft, with a shipping length of 22.2 ft and 8.2 ft width, optimized for transport and on-site maneuverability. The undercarriage includes 23.7-inch shoes on a 6.2 ft track gauge, providing stability and a max travel speed of 3.1 mph, with a ground pressure of 3.9 psi and a drawbar pull of 15,421 lbs, suitable for various terrains. The swing mechanism delivers a swing speed of 12.5 rpm and a torque of 14,060 lbs-ft. Hydraulic capabilities include a 53 gpm pump flow, a fluid capacity of 31 gallons, and a relief valve pressure rated at 4,250 psi, supporting smooth and powerful operation under load. Fuel capacity is 26 gallons, and electrical systems operate at 24 volts with a 30-amp alternator. The machine's compact tail swing radius of 5.5 ft enables efficient operation in confined spaces. Overall, the Kobelco 80CS is engineered for effective mid-size excavation with balanced power, reach, and mobility.
