Doosan DL420 Wheel Loader


Doosan launches the new DL420, an articulated wheel loader with a larger, more powerful diesel engine than the model DL400, which it replaces.

With a bucket capacity of 4,0 m3, the DL420 is designed to take on a wide range of material handling tasks from loading and transporting granular material (such as sand and gravel) to industrial, mining and quarrying applications. With the addition of the DL420, the Doosan range of articulated wheel loaders includes eight models with bucket capacities from 1,45 m3 to 5,0 m3.

The 22 300 kg DL420 is powered by a Cummins QSM11 engine with high pressure unit injector system and a state-of-the-art combustion system. Emissions are well below Tier 3 regulatory limits.

The engine develops 280 hp @ 2000 rpm and offers maximum torque of 1070 lb ft @ 1400 rpm for optimal traction and breakout force in loading-transport-handling applications. Depending on the application, the operator can choose between two working modes (standard or economy) for either maximum productivity or minimum fuel consumption.

A robust Z-bar lifting system provides a standard bucket breakout force of 21 400 kg, among the highest in its size class. This results in higher stripping force and greater productivity when working in hard materials.

The DL420 offers 4 forward speed ranges and 3 reverse speed ranges. Like all Doosan wheel loaders, the DL420 features a full powershift transmission with manual and automatic modes. Standard limited slip differentials on both the front and rear axles assure positive traction in wet or soft conditions.

The DL420 provides operators with improved visibility and lower cabin sound levels. A powerful heating and air conditioning system, a roomier cabin, ample storage space and a comfortable seat also help to reduce operator fatigue. Anti-pitch control provides smoother travel with a loaded bucket. Available as an option is a single lever control for travel functions and front-mounted attachments.
