Doosan mark 40 years with new product developments

25 Apr 2018

Fortieth anniversary of company’s construction equipment range to be celebrated at Hillhead 2018

DOOSAN Infracore Construction Equipment will be showing the company’s latest generation of excavators, wheel loaders and articulated dumptrucks (ADTs) for the quarrying, mining and construction markets on stand Z4 and in the demonstration areas at Hillhead 2018.  

Hillhead will be the platform for the UK launch of several new product developments, including a new version of the company’s successful 30-tonne DA30 ADT and new features on Doosan’s large wheel loaders.  

Hillhead will also be used celebrate Doosan’s achievements since 1978, when the first machines in the company’s construction equipment range were introduced. To mark the company’s successful growth over the 40 years since then, and the production of more than 400,000 units for markets worldwide during this period, Doosan machines at Hillhead will bear special Anniversary stickers that the company is putting on all machines for sale in 2018.

The changes in the new DA30 ADT model are signified by a new colour scheme for the machine that aligns it with other products in the Doosan Heavy range. Most of the changes are aimed at enhancing operator comfort and the controllability of the machine, but there are also changes in the driveline and electrical systems.

The most important development is in the suspension of the DA30, which has been upgraded to a hydro-gas self-levelling system that provides outstanding performance and superior shock absorption for better driving comfort, especially when the truck is being driven when empty. To complement this, the operator will now also benefit from a Grammer Actimo XXL seat, fitted as standard, with its own independent low-frequency pneumatic and wide scissors-type suspension.

This is not the only change in the new state-of-art operator’s cab on the DA30, which has been redesigned to provide better ergonomics and more operator comfort. The dashboard has a completely new layout and soft-touch material composition that is easier to clean, and features a new display as well as a high-quality finish and appearance.  

The cab also offers new safety and performance functions with a more comfortable control panel with a power cut-off switch and an LED indication lamp that indicates when it is safe to switch off the power cut off. Other features include a new easy-to-use lever for retarder steering, a new, more precise brake system for increased sensitivity and performance, an extra hand grip on the right-hand side, a USB charger and a 12V/24V power socket, together with more convenient compartment storage and electrically adjustable mirrors as standard.  

On the outside of the cab, a new all-round hand-grip rail has been installed for improved safety while moving round the exterior of machine for cleaning and other tasks. 

According to Doosan, the new version of the DA30 will deliver lower running costs as there are fewer service points and a reduced number of oil types in the driveline, as well as increased intervals for transmission oil changes. In addition, a new cab-tilting system allows the service technician to lift and close the cab in just a few minutes.

With these new features, the DA30 is said to establish a benchmark in load-carrying performance, fuel efficiency, enhanced controllability and operator comfort, together with improved reliability, durability and reduced maintenance and servicing costs.  

Doosan have also announced a wide range of new safety and ergonomic features on all six large Doosan wheel loaders – the DL300-5, DL350-5, DL420-5, DL450-5, DL550-5 and DL580-5 models.  

A number of the new features are aimed at increased safety and visibility in and around the operator’s cab. For example, a new handrail has been installed around the cab roof with three holding points, allowing operators to move safely around the cab to clean the windows etc.  

Inside the cab there is a new ergonomic joystick control with a progressive thumb wheel for the auxiliary hydraulic line (third valve). This ensures that no additional lever is needed and provides the easiest combination of movements to manage third-valve operations. In addition, FNR control has been relocated on the back of the joystick, via a three-position rocker switch, making it much more convenient and intuitive to use.  

To make life more comfortable and easier for operators, Doosan have added a rolling sunshield on the rear window to avoid any disturbance from sunlight during operations. The cup holder has also been relocated to the front right of the cab and a new double-hanger hook allows both a helmet and a jacket to be hung inside the cab.

The operator also has the benefit of additional convex mirrors installed on the lateral mirror frames. The wider angle and additional visibility provided by the convex mirrors along the side of the machine helps ensure safer manoeuvring of the wheel loader in the quarry.  

Along with these new features, Doosan have implemented a restyling for all the models in their wheel loader range. The new styling scheme involves a change of colour (from orange to dark grey) for the front lift arm, front frame and front and rear axle components, with the more dynamic curved lines of the new styling designed to reinforce the robustness and power of the Doosan wheel loader range.
