NEW crawler excavators complete with touch screen displays, bluetooth systems, and 166 horsepower engines have been unveiled by a leading manufacturer. 

Doosan has launched the 21 tonne DX210-7, DX210NLC-7 and DX210LC-7 models, offering a choice of short, long and narrow or long and wide track configurations, respectively.   

Among their features, each boasts the new "Tiltrotator Mode" on the control panel, which can be selected to ensure an optimized hydraulic flow and helps to maximize the accuracy of tiltrotator work by eliminating back pressure, and a smart hydraulic system that offers an improvement of around 30 per cent in attachment work.

The new DX210-7 short track model is "ideal for use on soft ground surfaces" where lower ground pressure is required and is a compact unit offering advantages for working in confined spaces and for transportation.

The DX210NLC-7 narrow track excavator is aimed at countries such as Italy, where either regulations or customer preferences call for the narrow track configuration.

Perfect for rental companies, the new DX210LC-7 machine has a similar long track set-up to Doosan’s heavier DX235LC model.

All three new 21 tonne models are powered by the latest generation Doosan DL06V six cylinder diesel engine, providing 124 kW (166HP) at 1800 RPM. This is combined with super-efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions.

The enhanced fuel efficiency of the DL06V engine in combination with a new hydraulic main valve and the new generation SPC3 Smart Power Controls provides increased fuel saving.

The new DX210-7, DX210NLC-7 and DX210LC-7 models utilise the hydraulic system used on Doosan’s heavier DX225LC-5 model, ensuring the operator has the fastest possible response, precision and hydraulic capacity to carry out their work.


Another standard new feature is the Fine Swing function which minimizes the shaking that a lifted object undergoes at the start or stop of a swing movement with the excavator, to increase the safety of nearby workers and to prevent damage caused by the object falling from the excavator.

When Fine Swing activates, the overrun disappears, allowing the excavators to smoothly reach maximum swing speed, whilst removing the shock from the turn reversal at the moment of stopping, resulting in a smooth stop.

The state-of-the-art cab on the new excavators excels in terms of spaciousness and ergonomics, taking operator comfort and ease of operation to new levels.

As well as a new high quality seat, the enhanced cab offers more features as standard than other machines on the market, ensuring super controllability and high precision in all applications.
