One of the many world premieres Doosan will make at Bauma 2022 is the launch of its new 4×4 Articulated Dump Truck (ADT). Adding to the company’s market-leading range of 6×6 ADT models, the new 4×4 version of the ADT DA45-7 is designed to compete with 40-tonne RDTs.

The new ADT DA45-7 4×4 arrives to complement Doosan’s current range of Stage V compatible ADT 6x6s, which includes the DA30-7 and DA45-7 models with payloads of 28 and 41 tonnes respectively.

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

More performance than RDTs in tough conditions

“With superior performance on rough roads, loose surfaces and sloping terrain, the goal of our new 4×4 machine is to compete with the RDTs in the 40-ton class, bringing to market a dump truck that offers so much more than the RDTs.”, says Beka Nemstsveridze, ADT Product Manager at Doosan.

As well as outperforming RDTs in tough conditions, the new 4×4 version of the DA45-7 ADT is less than 4m wide to avoid the need for special transport and offers a better turning radius than an equivalent RDT. A shorter turning radius and the design of the rear discharge unit, more suitable for transporting flat and heavy rocks, bring concrete advantages to the mining and tunneling industry.

The latter are growth markets for ADTs and include pioneering short-term mining projects, quarrying and contract mining industries, especially in southern Africa, the UK and Australia. Contractors in the construction and earthmoving industries working on highways, dams, airports, landfills, and development projects are also heavy users of ADT. Together, these areas make ADT’s market wide and varied, ensuring a large client base.

“The development of our ADT 4×4 has been inspired by the needs of our customers and the new ADT 4×4 can meet the demand of the international market by offering significant competitive advantages to customers with specific requirements. For example, a machine like this could extend the season of a mine that normally has to stop for a certain period due to, for example, the rainy season,” says Beka Nemstsveridze.

The new ADT DA45-7 4×4 has been developed at Doosan’s ADT plant located in Elnesvågen, near the Norwegian city of Molde. In addition to all the above benefits, Doosan’s new ADT 4×4 Stage V provides excellent payload capacity, fuel efficiency, easier controllability and great operator comfort, all coupled with improvements in reliability and durability and reduction of maintenance costs.

Summary of the advantages:

• The ADT 4×4 can climb steeper grades than equivalent RDTs.
• The ADT 4×4 performs better than the RDTs on wet and slippery surfaces.
• In heavy rain conditions, the RDTs may need to stop working; with the Doosan ADT 4×4 you don’t have to.
• Thanks to the short turning radius, the ADT 4×4 works effectively in tight spaces.
• The two-axle ADT 4×4 design causes less ground disturbance than 6×6 configurations.
