Doosan launches new 21-tonne excavators in three different configurations
Doosan has launched the company’s first 21-tonne crawler excavators - the new DX210-7, DX210NLC-7 and DX210LC-7 models, offering a choice of short, long and narrow or long and wide track configurations, respectively.
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, providing Doosan with another high performing option to offer customers in the 20 tonne sector. 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 (166 HP) at 1800 RPM. The DL06V engine offers a new solution to exceed Stage V regulations without exhaust gas recirculation (EGR), that boosts the quantity of air available during combustion, increasing the temperature of the process and greatly reducing the amount of particulates produced.
This is combined with super-efficient DOC/DPF+SCR after-treatment technology to ensure minimal emissions. Thanks to the new technology, maintenance of the diesel particulate filter (DPF) has been greatly reduced, with no maintenance required until the machine has operated for 8000 hours.
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. There are four power modes (P+, P, S or E) now available on the new models, which help to simplify the operation of the new excavators and can be set in both one-way and two-way working modes.
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. In addition to higher performance and cost savings, the new excavators offer more new features as standard than other machines on the market, many of which are common to the other new medium-sized excavators currently being launched by Doosan. These provide major enhancements in machine controllability, versatility, operator comfort, uptime and return on investment, with a strong focus on increased productivity and robustness.
