Both are powered by the Doosan DL06K ‘common rail’ 6-cylinder turbocharged diesel engine, using exhaust gas recirculation (EGR) and diesel particulate filter (DPF) after-treatment technologies.
Three working modes – Eco, Normal and Power –optimise fuel consumption for different applications. A ‘Power-Up’ function allows the operator to manually adjust to the next working mode by applying a full stroke of the accelerator pedal. With this feature, the operator can travel in Normal mode and switch to Power mode when it is needed, such as when taking material from a pile. The Eco bar provides information about fuel consumption in relation to machine performance in real-time, allowing the operator to select the driving mode for the best fuel efficiency.
If Auto Idle is activated, engine speed goes down about 200rpm after 10 seconds if there is no machine movement. Doosan claims that the Auto Idle feature reduces fuel consumption by up to 8%.
With bucket capacities of 2.0m3 and 2.5m3 respectively, the DL200-3 and DL250-3 wheel loaders are intended to meet a wide range of material-handling needs from loading and transporting granular material to industrial, mining and quarrying applications.
The new cab has a wider front glass section and an extended wiper blade area. Putting the reservoir for the wiper water on the outside of the cab has increased leg room inside. And the air conditioning system is now regulated automatically by a temperature sensor.
The new instrument panel has an integrated VCU (vehicle control unit, allowing the operator to choose the information they wish to have displayed. The operator can set a password for machine start.
Like all the new generation Doosan wheel loaders, the DL200-3 and DL250-3 models are equipped with load sensing controlled, variable hydraulic piston pumps, improving performance and reducing fuel consumption. With load sensing, the hydraulic pumps receive a signal from the MCV (main control valve) informing how much oil is needed. This helps to save on engine performance, Doosan says.
Optional extras include electric steering.
