New Doosan Products in Anniversary Year at Hillhead 2018



Doosan Infracore Construction Equipment will be showing the company’s latest generation of excavators, wheel loaders and articulated dump trucks (ADTs) for the quarrying, mining and construction markets on the company’s stand number Z4 and in the demonstration areas at the Hillhead 2018 Exhibition at Hillhead Quarry in Buxton, Derbyshire in the UK from 26-28 June 2018.        

Hillhead is the platform for the UK launch of several new products being shown at the exhibition for the first time, including a new version of the company’s successful DA30 30 tonne ADT and new features in the large Doosan wheel loaders. 

Hillhead will also celebrate Doosan’s achievements since 1978, when the first machines in the company’s construction equipment range were introduced, growing successfully over the next 40 years to position itself today as a top global player and to produce more than 400,000 units for markets worldwide in the same period.  To mark this, the Doosan machines at Hillhead will bear 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 also 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.

New Hydro-Gas Self-levelling Suspension

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

The Grammer seat 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 which 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 for moving round the outside of machine for cleaning and other tasks.  Doosan has also introduced a new position and solution for the power cut off switch.

According to Doosan, in the new version of the DA30, there will be lower running costs involved as there are a reduced number of service points with fewer different oil types in the driveline and increased intervals for transmission oil change. In addition, the new cab tilting system enables the service technician to lift and close the cab in just a few minutes.

With these new features incorporated, the DA30 establishes a unique benchmark in load carrying performance, fuel efficiency, enhanced controllability and high operator comfort, together with improved reliability, durability and reduced maintenance and servicing costs.

New Features on Large Doosan Wheel Loaders

Doosan has announced a wide range of new safety and ergonomic features on all six large Doosan wheel loaders including 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 very safely all around the cab to clean windows and to perform other tasks.

Inside the cab, there is a new ergonomic joystick control with a progressive thumb wheel added for the auxiliary hydraulic line (3rd valve).  The progressive thumb wheel ensures that no additional lever is needed, providing the easiest combination of movements to manage the 3rd valve operations.  FNR control has been relocated on the back of the joystick, via a three-position rocker switch, which is much more convenient and intuitive to use.

To make life more comfortable and easier for operators, Doosan has 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 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 ensure safer manoeuvring of the wheel loader on site and in the quarry.

Along with the new features in the large wheel loaders, Doosan has implemented a restyling for all the models in the company’s 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 on the machines.  The more dynamic curved lines of the new styling are designed to reinforce the robustness and power of the Doosan wheel loader range.
