Doosan Infracore Europe has unveiled its newest machine for the European industry that pairs best-in-class performance with lower fuel consumption and higher productivity: the DX1000LC-7 crawler excavator.
The 100-tonne model is the company’s largest-ever, with the most powerful engine in the 100-t class: the new stage V version of the well-proven Perkins 2806J diesel engine, providing a high power output of 469 kW (629 hp).
“The engine meets Stage V emission regulations by utilising exhaust gas recirculation, selective catalyst reduction, diesel oxidation catalyst and diesel particulate filter (DPF) after-treatment technologies,” the OEM said.
The DX1000LC-7 additionally features the highest hydraulic flow for this size of machine.
“The high output of the engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-ECOPOWER+) and controlled by electric manipulator (FEH), providing a best-in-class hydraulic flow of (3x 523) 1569 l/min and a high system pressure of 360 bar, together contributing to the best performance in the 100 tonne market,” the company said.
Specifically, the D-ECOPOWER+ FEH technology utilises an electronic pressure-controlled pump within a closed centre hydraulic system to optimise productivity and fuel consumption depending on mode. A closed centred main control valve minimises pressure loss, while the electric pressure-controlled pump manages and optimises engine power more effectively.
Inside the DX1000LC-7, there is a new and spacious operator cab equipped with ergonomic controls and instrumentation. Noise is minimised with enhanced sealing of the engine compartment and sound-dampening materials.
All of the components and assemblies on the new release have been built and tested to offer durability, including multi-stage filters and features including track guards and cylinder guards for the boom and arm, an auto grease system and greased and sealed track links.
To provide optimised operations, the DX1000LC-7 excavator operator can switch between two modes – boom or swing – to best match the application.
Other features include: a new 8-inch touch-enabled colour LCD gauge panel; stereo system integrated in the gauge panel (with Bluetooth streaming function); a keyless start system; 360-degree cameras (AVM, all-around view monitoring); side protection and catwalks; and more.
The DX1000LC-7 is primarily intended to serve customers in mining and quarrying applications for removing overburden and loading large amounts of material into articulated dump trucks or rigid frame trucks.
With this extension of its excavator line, Doosan now offers machines from 1 to 100 tonnes.
