Doosan’s New ADT Features

Doosan’s New ADT Features

Doosan has announced a wide array of new standard and optional features for the company’s articulated dump truck (ADT) range.

The first of the new standard features is an angle limitation system to prevent the truck body from tipping over when it is being loaded with materials. This new function is incorporated as standard on all ADTs manufactured after 1st January 2017 and is also available if requested by customers as a software update for all ‘-5’ machines produced before that date.

In the new angle limitation function, a tip limit point can be set to meet the requirements of the machine owner. This allows the body to tip in accordance with the slope of the ground as set by the system.

Based on a study of the customer’s application, Doosan can provide recommended limits for the company’s trucks, but it is up to the owner to decide which limits they want to use. If the slope is over the limit, the angle limitation system ensures the body does not move.

The function, therefore, offers increased safety and efficiency as the operator always knows the machine will be in a stable position.

ADTs can spend between 30 per cent and 60 per cent of their time standing with the engine idling while they are waiting to be loaded and, in some conditions, the waiting time can exceed 60 per cent, with consequent losses in terms of fuel, warranty and service costs.

In order to reduce these costs, Doosan has introduced the auto shut down function which can be switched on and off by the operator on the display. Using the system, the operator can set a time after which the engine will automatically shut down if the computer does not detect any activity in the machine.

This function is incorporated in all new Doosan ADTs and is available upon customers’ requests as a software update for machines produced before 1st January 2017.

Transmission oil levels are among the most complicated features to monitor but ensuring they are maintained at the correct levels is very important for keeping equipment in good shape and is crucial for extending the lifetime of machines and their proper functioning.

All new Doosan ADTs are now equipped with an electronic transmission oil level sensor (instead of a dipstick system) which will make oil level checks a much simpler and more reliable process to carry out.

Similar to those available in the automotive industry, Bluetooth radios are now a standard feature of all the Korean manufacturer’s ADTs. For an extra cost, buyers can also choose the alternative radios with the DAB+ function.

The Geofence system ensures the machine cannot leave a prescribed area. This is part of the machine software and can be set up using a Doosan ADT diagnostic tool.

Using the diagnostics, it is possible to adjust the Geofence boundaries and choose a speed limitation level (from 1 to 50 km/h, it is not possible to choose 0 km/h for safety reasons).

The speed limitation is activated 15 seconds after the machine crosses the boundaries of the area preset in the Geofence system. It is available from the factory on new Stage IV compliant DA30-5 and DA40-5 ADTs.

As standard, all units feature an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This together with a free-swinging rear tandem bogie ensures equal distribution of weight to each wheel and guarantees permanent 6-wheel contact and drive for equal power distribution and excellent performance on difficult terrain.

The DA30-5 and DA40-5 ADTs are powered by Scania DC9 276 kW (370 HP) and DC13 368 kW (493 HP) diesel engines, respectively, meeting the Stage IV/Tier 4 Final emission regulations through the use of both SCR and EGR technologies. The Stage IV/Tier 4 Final ADTs do not need a diesel particle filter (DPF) to meet the emission regulations.


Specifically designed by ZF for use on ADTs, the ZF EP countershaft transmission provides eight forward speeds, with a top speed of 55 km/h (34 mph), and four reverse speeds.

In the DA30-5 and DA40-5 models, the front differential is mounted directly onto the transmission, so there is no driveline that needs greasing and reducing the overall length of the machine for better weight distribution and a tighter turning circle.

With smaller equal gear steps between gears, and a higher overall gear spread (eight forward gears), the transmission works optimally with the engine for better fuel efficiency.


To meet strict safety rules demanded on some sites, customers can now order new Sears high performance heated seats. The new seats can be supplied with a choice of three different kinds of seat belt with a 2, 3 or 4 point design.

The rear position and direction lights on ADTs are now LED lights as standard, whilst the work lights, main lights and even the roof light bar are also available in optional LED versions. As well as improving visibility, the LED systems have longer lifetimes. Safety can also be increased by the additional hand rails for service and maintenance work that can now be installed on both the DA30-5 and DA40-5 ADTs.

There is also the option of a blue or orange flashing rear light, which is activated when in reverse gear and works simultaneously with the reverse lights. This is designed to be an excellent additional warning device, especially when working in the dark or on very noisy work sites where normal reverse signals may be not heard.

White Noise Reverse Alarm

An optional white noise reverse alarm can also be installed as a replacement for the standard reverse alarm. The characteristic sound of this alarm is not only easier on the ears but can offer increased safety on noisy job sites. To confirm that the driver is using their seat belt properly, there is also an optional green seat belt roof warning light available that can be placed on the cab roof.

Electrical Refuelling Pump
The optional electrical refuelling pump may be useful on some job sites as is the air inlet pre-cleaner, which complements the standard high performance 3-step cyclonic air filter in Doosan ADTs, particularly in very dusty areas where the increased amount of dust can cause shorter air filter lifetimes.

Painting System
As a final option, the availability of a new pre-assembly painting system allows ADT operators to customise their ADTs and specify particular colours if they wish to match them to their existing fleets.
