New DX255LC-5 excavator from Doosan
Latest 25-tonne Stage IV crawler excavator said to set new benchmark in excavator design
DOOSAN Construction Equipment have launched a new 25-tonne crawler excavator, the DX255LC-5, which, as well as meeting the latest Stage IV emission regulations, is said to set a new benchmark for excavator design worldwide and raises the performance standards already set by the previous ‘LC-3’ Stage IIIB range.
Offering enhanced comfort and controllability together with new features to boost uptime and return on investment, with a focus on increased power, robustness and agility, the excavator features a distinctive new styling scheme that is common to all new LC-5 machines.
Whilst overall dimensions are very similar to the previous LC-3 model, the DX255LC combines greater power with a 500kg increase in operating weight, resulting in increases of up to 17% in lifting capacities over both the front and side, and a 1dB(A) reduction in sound levels.
The DX255LC-5 excavator is factory installed with the new CoreTMS state-of-the-art wireless fleet-monitoring system, a feature not previously available as standard on Doosan excavators but now incorporated in all new LC-5 generation machines above 14 tonnes.
At the heart of the new DX255LC-5 excavator is the well-proven 6-cylinder, turbocharged Doosan DL06P water-cooled diesel engine which delivers an output of 141kW (189hp) at 1,900 rev/min, a 5% increase in engine power, and meets the Stage IV emission regulations 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 that reduce fuel consumption further by an average of 4% to 9% compared with the DX255LC-3 model.
The new cab in the DX255LC-5 has been further refined for operator comfort and ease of operation, including a new system that allows attachments to be operated from either the joystick or a two-way pedal. Users also have the unique jog shuttle switch which remains a feature exclusive to Doosan excavators worldwide.
New gauges, functions and menus have been added to the control panel, including a new AdBlue gauge, while a new quick-menu bar has been installed which allows key functions to be accessed quickly, without having to go through all the menus and validations.
A side-view camera is available as an option and the control panel allows the views from both the rear and side view cameras to be combined on the same screen, simply by pressing a button on the control panel.
To avoid permanent engine damage, an acoustic alarm has been added to call the operator’s attention to ‘water in fuel’. If the operator ignores the signal after several alerts, the engine and pump are automatically derated. Moreover, the engine emergency stop switch has been relocated on the side of the seat so that it is directly accessible from ground level, for faster access in case of emergency.
