Technical Description

The Case CX240B LR Excavator is a heavy-duty hydraulic excavator engineered for long-reach applications with a maximum digging depth of approximately 47.75 feet (about 14.56 meters). It is powered by a robust 177 horsepower (132 kW) Tier III-compliant common rail diesel engine, featuring four cylinders with a bore and stroke of 115 x 125 mm and a cubic capacity of 5193 cc, delivering high torque and fuel efficiency through electronically controlled fuel injection. The machine’s operating weight is 61,730 lbs (28,000 kg), balancing stability and mobility for demanding job sites. Its hydraulic system is advanced, offering three working modes that optimize breakout force, swing speed, and torque, achieving a breakout force up to 15,200 daN with a power boost function to enhance productivity by approximately 5%. The swing speed reaches 10.7 rpm with a swing torque of 7,490 daN, while the travel system, featuring axial piston variable flow motors, provides a maximum speed of 5.5 km/h and gradeability of 70%. The undercarriage features 800 mm triple grouser shoes, supporting stable operation on varied terrains. The long reach boom measures 10.3 meters combined with an 8.0-meter dipper, facilitating a maximum reach of about 18 meters and a vertical dig depth of 12.19 meters. The cab includes ergonomic controls, safety mirrors, and electronic management systems for speed and power, contributing to operator comfort and efficiency. Overall dimensions include a ground clearance of 18 inches, height to the top of the cab around 9.8 feet, and track width of approximately 11 feet, making this excavator well-suited for precision earthmoving and extended reach excavation tasks.
