High engine power combined with reduced fuel consumption are said to be key qualities of Doosan’s new DL200-3 and DL250-3 wheeled loaders.

Both new models are also said by the South Korean firm to provide better operator comfort, exceptional performance, ease of handling, easier serviceability and extended durability.

The wheeled loaders’ new cab design is said to offer greater visibility thanks to a wider front glass section and an extended wiper blade area.  Now that the reservoir for the wiper water is located on the outside of the cab, space inside has been increased, providing more foot room.  The air conditioning system is regulated automatically by a temperature sensor.

A new instrument panel has an integrated VCU (vehicle control unit). The control panel has been redesigned for more convenience, allowing the operator to choose the information they wish to have displayed.

The DL200-3 and DL250-3 are both powered by the 695 Doosan DL06K ‘common rail’ six-cylinder turbocharged diesel engine meeting Stage IIIB engine emissions regulations through the use of Exhaust Gas Recirculation (EGR) and Diesel Particulate Filter (DPF) after-treatment technologies.  

Three working modes - ECO, NORMAL and POWER – are said by Doosan to allow optimum fuel consumption for different applications.  With the ‘Power-Up’ function, the operator can manually adjust to the next highest 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.

The operator can set a password for machine start. If Auto Idle is activated, engine speed is said to go down by around 200rpm after 10 seconds if there is no machine movement. Auto Idle is described as ideal for applications with longer waiting times, such as truck loading. Thanks to this facility, fuel consumption is claimed by Doosan to be reduced by up to 8%.

On both wheeled loaders, the lift arm has been strengthened with thicker metal in the tilt lever.

New kinematics and a larger cylinder on the lift arm have allowed the main pressure in the front hydraulic system to be increased, with a corresponding increase in breakout and lifting forces.

The SKF Vogel Auto Lubrication system, said to improve the lifetime of the machine and increase its operational hours for better productivity, is available as an option.  

With bucket capacities of 2 and 2.5m³ respectively, the DL200-3 and DL250-3 wheeled loaders are intended to meet a wide range of material handling needs from loading and transporting granular material to industrial, mining and quarrying applications.
