Doosan DX225LC-7M
Crawler Excavator
The Doosan DX225LC-7M crawler excavator is perfect for those tough digging tasks, making sure you stay productive all day long.
Looking for a powerful excavator that doesn’t sacrifice fuel efficiency?
The Doosan DX225LC-7M crawler excavator is perfect for those tough digging tasks. It has a one-touch power boost button and an exclusive D-ECOPOWER system to make sure you stay productive all day long.
You need an excavator that can handle general construction and excavation applications, and the DX225LC-7M delivers. With its conventional tail swing design and optional dozer blade, this machine gives you the strength and leverage you need to get the job done right.
Excavate with precision and accuracy
With the Doosan DX225LC-7M crawler excavator, that’s exactly what you’ll get. The machine has a fine swing function which will minimise the shaking of a lifted object, giving you greater control and accuracy. Plus, there are two optional intelligent floating boom modes which will allow the boom to move freely with the ground contours.
The travel function’s auto downshift is intended to boost drawbar pull as necessary, enhancing the machine’s responsiveness and controllability. Additionally, the alternative straight travel mode is the best option for transporting and trenching activities. Standard, long, and super-long reach excavator arm combinations are also available.
If precision excavation is what you need, the Doosan DX225LC-7M crawler excavator is perfect for you!
Designed for Comfort and Productivity
Doosan has you covered with the DX225LC-7M. It comes packed with features like the Doosan Smart Touch display, ergonomically designed joystick controls, optional heated / cooled seat and automotive-style heating and cooling, and the Doosan Smart Key – so you can work more comfortably all day long.
You may get a complete picture of the machine’s surroundings with the optional 360-degree all-around view monitoring (AVM), which improves your worksite awareness in all directions. A rear-view camera and eight high-illumination LED lights are included as standard features, so you won’t have any problem seeing what you’re doing in low light conditions. There is an upgrade option to 12 LED lights.
Get an excavator that is built to last
Your demands were taken into consideration in the creation of the Doosan DX225LC-7M crawler excavator. It boasts an X-Chassis undercarriage for increased stability and longevity, a strong working group with a strengthened steel-casted push link, and other characteristics. All filters will be conveniently accessible from the ground, and frequent check locations will be nearby.
You can operate worry-free thanks to an inventive D-channel upper structural frame design that increases strength to safeguard crucial components. A hinged belly pan offers access from the bottom, and the big engine cover gives plenty of clearance to reach the top side of the engine.

hydraulic system
The heart of the system is the e-EPOSTM (Electronic Power Optimising System). It allows the efficiency of the system to be optimised for all working conditions and minimizes fuel consumption.
The new e-EPOS is connected to the engine electronic control via a data transfer link to harmonise the operation of the engine and hydraulics.
