DOOSAN DX340LC CRAWLER EXCAVATOR

Technical Description

The Doosan DX340LC is a robust hydraulic crawler excavator engineered for demanding construction and earthmoving applications. Powered by a Common Rail DL08 engine, this machine delivers 247 horsepower at 1,750 rpm with a maximum torque of 846 lb-ft, providing exceptional digging force at low engine speeds. The excavator features an operating weight of 75,178 pounds and accommodates three boom and stick configurations, with maximum digging depths ranging from 22.8 to 27.2 feet and maximum reach along the ground extending from 34.1 to 38.6 feet, depending on the selected attachment. The hydraulic system employs two variable displacement axial piston pumps delivering 140.1 gallons per minute at a system relief pressure of 4,699.3 psi, enabling precise control of independent or combined operations. The machine features dual travel speeds offering either increased torque or higher-speed tracking capability, optimized through a cross-sensing pump system for fuel efficiency. The swing mechanism operates at 8.9 rpm with efficient power management. Dimensionally, the DX340LC measures 10.8 feet wide with a 13.3-foot track length and 1.7-foot ground clearance, providing excellent stability and maneuverability on varied terrain. The undercarriage utilizes 48 shoes per side with a ground pressure of 9.2 psi, distributing weight effectively to minimize surface impact. The machine supports bucket capacities from 1.7 to 2.4 cubic yards, accommodating diverse material handling requirements. Its 145.3-gallon fuel capacity and electronic control systems optimize operational efficiency while reducing fuel consumption.
