First DX350LC-7 in Italy helps secure riverbed

Doosan DX350LC-7 crawler excavator

New 36-tonne Doosan excavator used to repair catastrophic storm damage in northern Italy

THE first new 36-tonne Doosan DX350LC-7 crawler excavator in Italy has helped to secure the bed of But creek, a tributary of the river Tagliamento in the province of Udine, in northern Italy.

Part of a fleet of Doosan equipment that includes two further crawler excavators, two articulated dumptrucks and a wheel loader, the DX350LC-7 is involved in clean-up and safety operations along a 4km stretch of riverbed, to repair damage caused by the catastrophic Storm Vaia at the end of 2018.

The new DX350LC-7, which was purchased by Mingotti T. Srl to rebuild bank defences and reprofile the bed of the creek, proved to be the ideal choice for moving 200,000 cubic metres of material from the bed and laying of more than 5,000 tonnes of boulders for the construction and repair of the embankments.

‘The DX350LC-7 represents our latest purchase,’ said Francesco Mingotti, technical director of Mingotti T. Srl. ‘Over the years, we have appreciated Doosan’s attention to fuel consumption, which on the new Doosan engine-powered DX350LC-7 is only 19 litres per hour. This is better than other machines on the market and is combined with excellent productivity.

‘By our calculations, this equates to moving about 250 cubic metres more material per day and fuel savings of about 38 litres per day, compared with other machines.’

The DX350LC-7 features Doosan’s innovative D-ECOPOWER technology, which is said to improve productivity, offer more control of the machine and reduce fuel consumption. The system uses nine sensors to determine and meter the precise amount of hydraulic oil necessary to accomplish a specific task, rather than continuously forcing a fixed amount of oil through the system, thereby improving efficiency. 

To meet Stage V engine emission regulations, the new DX350LC-7 excavator is powered by the latest generation Doosan DL08V diesel engine, providing 209kW of power at 1,800 rev/min. 

The DL08V 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 particulate matter produced. This is combined with DOC/DPF+SCR after-treatment technology to ensure minimal emissions.

Already excelling in spaciousness and ergonomics, the enhanced cab on the DX350LC-7 model features a new high-quality seat and is said to offer more features as standard than other machines on the market, ensuring superior controllability and high precision in all applications.
