DOOSAN DX255LC-5 CRAWLER EXCAVATOR

Technical Description

The Doosan DX255LC-5 is a mid-sized crawler excavator engineered for demanding earthmoving operations, combining robust performance with fuel efficiency. Powered by a Doosan DL06P Tier 4 Final compliant diesel engine producing 189 gross horsepower and 593 pounds-feet of torque at 1,400 rpm, this machine delivers reliable power output while meeting stringent emissions standards through CEGR, DOC, and SCR technology with DEF injection. The excavator's hydraulic system features a main pump capacity of 115.8 gallons per minute with dual relief pressures—4,978 psi normal and 5,263 psi boost—providing responsive digging force and smooth operation across variable workloads. With an operating weight of 57,752 pounds and a 5.9-liter displacement engine, the DX255LC-5 offers excellent mobility on tracked undercarriage equipped with 51 shoes per side and a 62,832-pound drawbar pull capacity. The machine excels in precision digging applications, achieving a maximum digging depth of 24 feet and maximum digging reach of 34.8 feet with boom/stick option one configuration. Its compact tail swing radius of 10 feet and shipping dimensions of 33.2 feet length and 11.1 feet height facilitate transport and maneuverability in confined job sites. Standard features include an 85-amp alternator, 24-volt electrical system, and fuel efficiency technologies including Smart Power Control (SPC) with variable speed and pump torque control, optimizing performance while reducing consumption. The machine accommodates 111 gallons of fuel, 74 gallons of hydraulic fluid, and operates at travel speeds ranging from 2 to 3.5 miles per hour across low and high ranges respectively, making it suitable for construction, quarrying, and general excavation work.
