10,000th ADT Leaves the Production Line in Norway

After 50 years of production, the Elnesvågen plant outside Molde in Norway, where the Doosan range of Articulated Dump Trucks (ADTs) is produced, is this month celebrating the completion of the 10,000th machine to be built at the plant. According to Plant Manager, Jan Roger Lindset, the Doosan ADT with production number 851951 is to be delivered to Rental Group in Norway.

Production began at the plant in 1972 when the business was called Glamox. Since then, the brand has had a number of names such as Moxy, Moxy Industrial, Brown Engineering, Moxy Trucks, Moxy Engineering and in 2008, the name changed to Doosan when the South Korean manufacturer bought the factory and the product. In 2021, Hyundai Heavy Industries bought the Doosan construction equipment range including the ADT line, and the name of the business was changed to Hyundai Doosan Infracore (HDI).

There are currently 150 employees at the Elnesvågen plant, but with both Doosan and Hyundai ADTs now being produced at the factory, the workforce is expected to expand to meet an expected 40% growth in production.  

The Doosan ADT Range – Best-in-Class Performance

The Doosan ADT range comprises two 6×6 models – the DA30-7 and DA45-7 Stage V compliant machines – the DA30-7 has a payload of 28 tonne, while that of the DA45-7 is 41 tonne. The range was extended at Bauma 2022 with the launch of a new 4×4 version of the DA45-7 ADT, intended to compete with rigid dump trucks (RDTs) in the 40-tonne class.

Like all Doosan ADTs, the DA30-7 and DA45-7 models feature an articulation hinge positioned behind the turning ring to provide equal weight distribution to the front axle even during maximum steer articulation. This combined 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 particularly on difficult terrains such as soft ground, uneven surfaces, very steep slopes, tight turns or a combination of all of these difficult conditions.

Collectively, the forward turning point, the unique tandem bogie and the sloping rear frame results in ‘best in class’ rough and soft terrain capabilities. The unique body shape and sloping frame ensure equal load distribution on all the wheels making these machines the best haulers for soft terrain work. The design of the articulation also provides equal load distribution on the wheels on both the left and right hand side when turning, which is very important for the traction and stability of the machines. All of these outstanding features are available on the Doosan Stage V DA30-7 and DA45-7 ADT models.

In the new 4×4 ADT, the front truck and cab unit is the same as in the original 6×6 model, with modifications being made on the rear dumper unit only. Featuring a ZF EP8-420 transmission, the 4×4 DA45-7 is a two-axle ADT with twin wheels at the rear, and with a dumper section similar to that on RDTs in the 40-tonne class.

Superior Performance in Difficult Conditions Compared to RDTs

“With superior operation on poorer roads, smoother surfaces and steeper terrain, the aim of our new 4×4 machine is to challenge RDTs in the 40-tonne class, by providing a dumper product that delivers much more than RDTs,” says Beka Nemstsveridze, ADT Product Manager at Doosan.

As well as performing better in conditions that are tough for RDTs, the new 4×4 DA45-7 ADT has a width of less than 4 m to avoid the need for special transportation and offers a better turning radius than a comparable RDT. The shorter turning radius and the design of the rear dumper unit, which is more suited to carrying flat and heavy rocks, provide particular advantages in the mining and tunnelling industries.  

The latter are growing markets for ADTs, and include pioneering, short-term mining projects, quarrying and contract mining industries, especially those in southern Africa, the UK and Australia. Construction and bulk earthmoving contractors involved in roads, dams, airports, landfills and development projects are also large users of ADTs. Together these areas make the ADT market a wide and varied one, thereby ensuring a large customer base.
