Doosan Rolls Out Updated Excavator

Doosan's DX180LC-5 crawler excavator is a 129 hp, Tier 4-compliant machine that features improved performance, operator comfort, fuel economy and jobsite durability, the company says. The Tier 4-compliant model replaces the interim Tier 4 (iT4) DX180LC-3 crawler excavator.



DX180LC-5 The machine features Smart Power Control, which uses Variable Speed Control and Pump Torque Control to improve machine efficiency while maintaining productivity and reducing fuel consumption. The variabile speed control reduces engine rpm during low workload requirements such as during the swing portion of a dig cycle. This reduces the total energy required to perform a task and improves fuel efficiency by up to 3 to 7 percent. Pump torque control matches hydraulic pump torque and engine response to the task, preventing engine overload and excess fuel consumption, improving efficiency.

• Horsepower (net): 129 hp
• Operating weight: 43,224 lb.
• Max. digging reach (ground): 29 ft. 7 in.
• Max. digging depth: 20 ft.
• Max. loading height: 21 ft. 3 in.
• Bucket digging force: 28,881 lbf.
• Arm digging force: 20,503 lbf.
• Four power modes
• Four work modes

An improved 7-inch liquid-crystal display (LCD) screen allows operators to monitoring the excavator parameters while viewing the rearview or side-view camera image. An auto-shutdown system helps save fuel during non-working conditions. 

The Doosan DX180LC-5 engine is optimized for use with a high-pressure common-rail (HPCR) fuel delivery system and a cooled exhaust gas recirculation (CEGR) system. It utilizes a diesel oxidation catalyst (DOC) to reduce particulate matter (PM) and selective catalyst reduction (SCR) aftertreatment to reduce nitrogen oxides (NOx). Additionally, a variety of aftertreatment systems have been implemented as part of Tier 4 compliance, such as DEF, which is used with SCR technology.

Doosan excavators come with a standard three-year subscription to Doosan Telematics,
