Doosan upgrades wheel loaders

Doosan Construction Equipment has launched the company’s new high performance ‘DL-5’ generation Stage IV compliant wheel loaders, the new DL300-5, DL350-5 and DL420-5 models, replacing the successful DL300-3, DL350-3 and DL420-3 Stage IIIB loaders launched in 2012. Providing another leap forward in wheel loader design represented by new external styling, the DL-5 range offers increased productivity and fuel economy, with features such as a new high comfort cab, powerful Scania Stage IV engines, smooth and responsive hydraulics, a ZF powertrain, axle cooling and auxiliary hydraulic connections. As in the previous DL-3 range, most of these features are standard on the new DL-5 wheel loaders unlike other machines on the market where they are options and many have been developed to optimise fuel efficiency.

The DL300-5 and DL350-5 wheel loaders are powered by the Scania DC09 5-cylinder diesel engine, with an output of 202 kW (271 HP) of power at 1800 rpm. The DL420-5 is powered by the Scania DC13 6-cylinder engine producing 254 kW (345 HP) of power at 1800 rpm. Providing generous torque at low rpm, up to a 10% reduction in fuel consumption and excellent response, the Scania engines meet 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.

The DL300-5, DL350-5 and DL420-5 are factory-installed with the new CoreTMS state-of-art wireless fleet monitoring system, a feature not previously available as standard on Doosan wheel loaders and now incorporated in all new DL-5 generation machines. The new CoreTMS system is a tool designed specifically for the Doosan range, providing comprehensive information about machine performance in a dual mode (satellite, Mobile network).

The CoreTMS system offers a web-based fleet and asset management solution which is very useful for managing the performance and security of machines and promoting preventative maintenance. The system can support multiple Doosan machines in different locations, helping customers to monitor machine utilisation rates to assess that the right mix of machines is being used; it can also guide drivers to help them to operate equipment with higher efficiency and to locate replacement machines in the event of maintenance work or breakdowns, all under the umbrella of vigorous anti-theft and theft recovery protection systems.
