New Doosan DX225SLR-5 Super Long Reach Excavator
Doosan Construction Equipment has launched a new super long reach version of the company’s Stage IV compliant DX225LC-5 crawler excavator.
Featuring 8.5 m boom and 6.2 m arm components, the new DX225SLR-5 excavator is an all-round machine, ideally suited for jobs such as excavating lakes, cleaning settling banks, drainage work, digging in sand and gravel pits, slope forming and other long reach work.
To carry out these applications, the DX225SLR-5 has a maximum digging reach of 15.38 m, a maximum digging depth of 11.65 m and a maximum digging height of 13.08 m. The bucket digging force is 10.0 tonne and the arm digging force is 6.0 tonne.
With an operating weight of 24.4 tonne, the DX225SLR-5 is powered by the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine, providing a high power output of 124 kW (166 HP) at 1800 RPM. As a result, the DX225SLR-5 combines its super long reach capability with unmatched high performance, operating features, fuel efficiency, reliability and durability.
The DX225SLR-5 offers convenience and lower costs by meeting Stage IV emission regulations through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies. With the DL06P engine, the DX225SLR-5 ensures trouble-free performance as it operates without the need for a diesel particulate filter (DPF).
As well as the DL06P engine, which is one of the most reliable and fuel efficient ever produced by Doosan, new innovative and exclusive features have been introduced providing an overall 9% increase in fuel efficiency. Among these features is the new ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel and to save even more fuel, there is a special Doosan-developed system, Smart Power Control (SPC), to optimise the balance between the pumps’ output and the diesel engine.
The Auto Shut-Off feature saves on fuel and warranty hours. When the feature is enabled, the engine shuts down after it has been idling for a specified amount of time (3-60 minutes, configurable by the operator).
The DX225SLR-5 is factory-installed with the DoosanConnect state-of-the-art, wireless fleet and asset management system for the company’s excavator, wheel loader and articulated dump truck ranges.
Designed to meet increasing demand for fleet monitoring, machine-to-machine communication, machine intelligence and remote equipment monitoring, the DoosanConnect system offers a web-based fleet management solution which is very useful for monitoring the performance and security of machines and promoting preventative maintenance. It is available as a standard feature on all new generation Doosan Stage IV compliant excavators (from 14 tonne), all new generation Doosan Stage IV compliant wheel loaders and the new generation Doosan Stage IV compliant ADTs.
The new service allows owners and dealers to remotely monitor and communicate with Doosan machines via the DoosanConnect telematics website. Also available for retro-fitting in a kit form, the DoosanConnect system is supplied with a free 3-year subscription and customers are provided with their own account so that they can manage the machines in their fleet using the system. Once the 3-year complementary period expires, customers have the option to purchase a service extension.
Spacious Ergonomic Cab
Already excelling in spaciousness and ergonomics, the cab on the DX225SLR-5 is bigger than that in the previous DX225SLR-3 and has been further refined for outstanding operator comfort and ease of operation. The features offered as standard in the cab are among the best in the market and include super controllability with a system that enables attachments to be operated from either the joystick or a two-way pedal. The operator can select 10 pre-set configurations for attachments and hydraulic flow and pressure data can be pre-selected directly from the control panel, allowing a quick change of attachments without the need for a manual set-up.
The joysticks have also been shortened to reduce the effort required to operate them and an additional pedal for straight travel has now been installed on the left of the main travel pedals, a very useful feature when travelling straight over longer distances. The operator console has been moved onto the seat suspension to reduce vibrations. This gives the operator much better control with the joystick in rough operation.
Lower Total Cost of Ownership
Like all Doosan ‘-5’ excavators above 20 tonne, the DX225SLR-5 incorporates a thicker inside plate in the arms and booms, providing front reinforcement to relieve stress concentration and a different welding method has also been applied. To further maximise durability and reduce noise, all ‘-5’ models are equipped with EM (Enhanced Macro-surface) bushings, which are also much more effective than regular bushings when greased.
Air pre-cleaners are fitted as standard on the DX225SLR-5, to blow much of the dust, dirt, insects, rain and snow out of the air intake, to ensure cleaner air is sent to the engine air filter. This extends air cleaner servicing intervals, enhancing uptime and productivity. Doosan has also added protection to the inner cab air filter and redesigned the cab air-conditioning filters for easier replacement.
A Trimble Ready option is available for the DX225SLR-5, enabling a faster and simplified installation of Trimble® 2D or 3D Grade Control System components − with no welding, repainting, drilling or disassembly required.
