The Doosan DX140LC-5

Doosan will bring its new 5 tonne DX57W-5 Stage IV-compliant wheeled excavator to Bauma, with new features the company promised would increase performance, durability and fuel efficiency.

Among the features is increased power from the 42.5kW Doosan D24 four-cylinder engine, which also meets Stage IIIB emission regulations without the need for a diesel particulate filter (DPF). It manages this by using cooled exhaust gas recirculation (EGR) and diesel oxidation catalyst (DOC) technologies.

Factory tests, said Doosan, had shown a 15% increase in fuel efficiency, depending on the mode of operation and the work being done.

Operator comfort features include more interior space in the cab, a more ergonomic grouping of the controls, and an adjustable 17.5cm LCD monitor.

The DX140LC-5 14-tonne crawler excavator is another newly-launched machine on show at Bauma, and Doosan said the model offered greatly-improved performance, compared with the previous LC-3 Stage IIIB model.

It claimed a 5% increase in engine power, 4% greater torque, a 10% increase in front lifting capacity and 18% more drawbar pull.

Up to 3% lower fuel consumption is claimed, as well as reduced emissions from a Perkins 1204F engine.
