Doosan DX255LC Crawler Excavator Features Several Updates Including Smart Power Control (SPC)

The 184-horsepower Doosan DX255LC-5 crawler excavator has been added to the Tier 4-compliant lineup, featuring improved performance, operator-focused comfort, fuel economy and jobsite durability. The Tier 4-compliant model replaces the interim Tier 4 (iT4) DX255LC-3.

A new selectable feature, Smart Power Control (SPC), consists of two systems — Variable Speed Control and Pump Torque Control — that work together to improve machine efficiency while maintaining productivity and reducing fuel consumption. The engine control unit (ECU) automatically manages SPC when SPC is engaged. Each of the four power modes will function with SPC engaged or disengaged; however, SPC can be active only in the digging work mode. The Variable 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 3-7 percent. Pump Torque Control efficiently matches hydraulic pump torque and engine response to the task, preventing engine overload and excess fuel consumption, improving efficiency.

 

Display enhancements

An improved 7-inch LCD screen allows operators to continue monitoring the excavator parameters while viewing the rear view and/or side-view camera image. Critical machine data appears next to the camera view. With an optional side camera, a split screen allows both camera displays to be viewed at once. New additions to the monitor include the DEF gauge and improved fuel efficiency.

To help save valuable diesel fuel, Doosan added auto-shutdown to its excavators to help owners save fuel during non-working conditions. Operators can configure the idle time from 3 to 60 minutes. When enabled, the feature will shut down the excavator’s engine when the preset idle time is met.
