The 30-t DX300LC-5 crawler excavator from Doosan has won the EquipmentWatch Lowest Cost of Ownership (LCO) Award in the Excavators Crawler Medium category for the second year running.
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. They are organised by EquipmentWatch, a world leader in data, software and insights for the heavy equipment industry. Nominees are recognised within 15 different categories of machines 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 purchasing equipment and the award won again 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.
The DX300LC-5 is powered by the Doosan DL08 6-cylinder diesel engine, with an output of 202 kW of power at 1 800 rpm, providing a 27% increase in engine power and a 30% boost in torque over the previous 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.
As well as the Doosan engine, the DX300LC-5 in common with all Doosan Stage IV machines has innovative and exclusive features that lead to huge reductions in fuel consumption amounting to an average of 10% compared to the Stage IIIB machine. Among these features is the ‘Trip Meter Setting’ screen which allows operators to check fuel consumption daily (or over a desired period) directly from the control panel; the 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.
To further maximise durability and reduce noise, the DX300LC-5 and all other Doosan LC-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, 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.
