Complementing the company’s standard range of 6x6 ADT models, the new 4x4 version of the DA45-7 ADT is intended to compete with rigid dump trucks (RDTs) in the 40-tonne class.
The new 4x4 DA45-7 ADT complements the current market-leading range of Stage V compliant 6x6 ADTs from Doosan, which includes the DA30-7 and DA45-7 models with payloads of 28 and 41 tonnes, respectively.
In the new 4x4 ADT, the front truck and cab unit is the same as in the original 6x6 model, with modifications being made on the rear dumper unit only. Featuring a ZF EP8-420 transmission, the 4x4 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.
“With superior operation on poorer roads, smoother surfaces and steeper terrain, the aim of our new 4x4 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 4x4 DA45-7 ADT has a width of less than 4m 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 tunneling 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.
In addition to the new DA45-7 ADT, Doosan is also presenting a range of other new state-of-the-art machine and digital technologies on the company’s Stand No FM.711/1 in the Open-Air Area Middle construction and mining machinery section of the bauma 2022 show.
The Doosan stand is centred around a dedicated Innovation Centre and, under the theme of Powered by Innovation, will present the latest developments in the company’s leading edge Concept-X, Xitecloud and DoosanCONNECT systems, together with other products such as what it says is the world’s first ‘Transparent Bucket’ and the new DX225LC-7X, Doosan’s first ‘Smart’ Crawler Excavator.
As well as the new DX225LC-7X, the array of products on the Doosan stand will show the increasing expansion at both ends of the product range for the first time at bauma. At the top of the range, these will include the new DX1000LC-7 100 tonne crawler excavator, the DL580-7 wheeled loader and a brand new 4x4 version of the Doosan DA45-7 articulated dump truck (ADT). At the compact end of the Doosan range, the company’s new 2 to 5 tonne mini-excavators and new 10 tonne midi wheeled excavator will be shown for the first time alongside the new Doosan range of compact wheeled loader models. Another bauma exclusive will be a preview of the first zero-emission mini-excavator from Doosan, the DX20Z-E, due to be launched in 2023.
