Award Winning Doosan

Working in the Doosan outside demonstration area at Intermat 2018, the 30 tonne DX300LC-5 crawler excavator has won the Lowest Cost of Ownership Award for the Excavators Crawler Medium category in a new annual series of awards organised by EquipmentWatch, a world leader in data, software and insights for the heavy equipment industry.

The Lowest Cost of Ownership Awards are the industry’s only accolade of their kind, based on empirical data regarding the long-term cost of heavy and compact equipment. Nominees were recognised within 15 different categories of machine that exhibit the lowest cost of ownership over a five year span.

Total cost of ownership is one of the most important aspects that buyers take into account when they purchase equipment and the award won by the DX300LC-5 shows why Doosan equipment is always rated highly for great performance and value-for-money. The award is a further illustration of why Doosan is one of the world’s top construction equipment manufacturers.

Many of the reasons behind the DX300LC-5 winning the Excavators Crawler Medium Award are evident in the greatly improved performance it offers compared to the previous ‘LC-3’ Stage IIIB model.

The DX300LC-5 is powered by the Doosan DL08 6-cylinder diesel engine, with an output of 202 kW of power at 1800 rpm, providing a huge 27% increase in engine power and a massive 30% boost in torque over the LC-3 model. The engine meets Stage IV emission regulations without the need of a diesel particulate filter (DPF), through the use of cooled exhaust gas recirculation (EGR) and selective catalyst reduction (SCR) after-treatment technologies.

New innovative and exclusive features have been introduced in the DX300LC-5, leading to huge reductions in fuel consumption amounting to an average of 10% compared to the Stage IIIB machine.

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; the new Auto Shut-Off provides an automatic shut down for the engine after a pre-set time when the machine has been idling for a specified time (3 to 60 minutes configurable by the operator); and to save even more fuel, there is a special Doosan-developed system, SPC (Smart Power Control), to optimise the balance between the pumps’ output and the diesel engine.

Doosan has also added protection to the inner cab air filter and redesigned the cab air-conditioning filters for easier replacement. Recommended for dusty environments (such as quarry applications), the oil bath (9.5 l) pre-cleaner is available as an option to remove dust from the air intake, extending air cleaner servicing intervals dramatically.

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.

The DX300LC-5 is factory-installed with the Doosan Connect state-of-the-art wireless fleet monitoring system. The Doosan Connect 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.

As well as the Excavators Crawler Medium category won by the DX300LC-5, other categories included those entitled Backhoes, Dozers Track Large and Motor Graders. The S70 skid-steer loader and MT55 mini track loader from Doosan’s sister company, Bobcat, won the Lowest Cost of Ownership Awards in the categories entitled Skid Steer Loaders and Loaders Compact Track, respectively.
