Doosan launch new-generation wheel loader

Doosan DL300-3

According to Doosan Infracore Construction Equipment, their new-generation DL300-3 large wheel loader will set new benchmarks for performance, ease of handling, serviceability, durability and operator comfort. With a bucket capacity of 3.0m3, the Stage IIIB-compliant loader is intended to meet a wide range of material-handling needs from loading and transporting granular material such as sand and gravel to industrial, mining and quarrying applications.

The DL300-3 model is powered by a 9-litre Scania DC09 five-cylinder diesel engine that delivers a maximum power output of 202kW at 1,800 rev/min and meets Stage IIIB emission regulations through the use of the SCR (selective catalytic reduction) and DPF (diesel particulate filter) after-treatment technologies.  

It is also equipped with a new ZF five-gear transmission that improves the transfer of power from the engine to the wheels and contributes significantly to the overall reduction in fuel consumption. There is now less engine speed variation thanks to smaller gear steps, while lower engine speeds throughout the whole drive range help reduce fuel consumption.


The DL300-3 loader has three engine working modes (Eco, Normal and Power) to adapt the machine to different applications, with varying engine speeds and gear steps according to the working mode engaged. 

The wheel loader features new ZF limited-slip Type II differential axles providing more durability and a longer service life. Rolling resistance for the axles has been reduced, improving traction and fuel economy. Customers also have the option to specify ZF axles with a hydraulic differential lock. This function is engaged via the operator pedal or in automatic mode, the advantage being that the hydraulic lock system has less rolling resistance compared with the limited-slip system. 

In common with all next-generation Doosan wheel loaders, the DL300-3 is equipped with load-sensing controlled variable hydraulic piston pumps and an SKF Vogel auto-lubrication system.
