The Doosan DX140LC-5 is a compact crawler excavator engineered for versatile construction and earthmoving applications. Powered by a Perkins 1204F Stage IV diesel engine rated at 113-115 horsepower with a maximum torque of 1,301 foot-pounds at 1,400 rpm, this machine delivers optimal power and fuel efficiency through its high-pressure common rail system and Electronic Power Optimizing System (EPOS). With an operating weight of 32,783 pounds and a maximum digging depth of 20.2 feet, the excavator provides excellent stability and reach capabilities, featuring a maximum digging height of 28.7 feet and a maximum reach along the ground of 27.9 feet. The hydraulic system operates at relief pressures of 4,694-4,978 psi with a 45-gallon fluid capacity and 39.7-gallon tank, delivering maximum traction force of 35,935 pounds through independent axial piston motors for each track. The swing mechanism provides 10.7 rpm rotation with 4,800 kilogram-force meters of torque, enabling precise positioning and smooth operational cycles. Travel speeds reach 3.0-5.0 km/h with a maximum gradeability of 70 percent, supported by 46 shoes per side and multi-disc track brakes. The undercarriage features a 600mm standard track shoe width and 8.4-foot width, while the bucket capacity ranges from 0.5 to 0.6 cubic yards.
