DX140LC-7

The new DX140LC-7 14.6 tonne and DX140LCR-7 15.9 tonne crawler models. Both excavators are now powered by the Doosan D34 4-cylinder Stage V diesel engine providing 87.2 kW (117 HP) of power at 2000 RPM

The D34 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. The enhanced fuel efficiency of the D34 engine in combination with a new hydraulic main valve and the new generation SPC3 Smart Power Controls, provides increased fuel saving compared to the previous generation machines. 

Both new models combine enhanced comfort and controllability together with a range of features to boost fuel efficiency, uptime and return on investment, with a focus on increased power, productivity, robustness and agility. In addition, the DX140LCR-7 is a reduced tail swing model, allowing operators greater flexibility where space is a premium without sacrificing performance. The DX140LCR-7 also has a new counterweight design that offers enhanced service accessibility.
