Doosan will launch its new 4×4 articulated dump truck (ADT) as part of several world premieres at Bauma 2022, the company has announced.
Complementing the company’s standard range of 6×6 ADT models, the company says the new 4×4 version of the DA45-7 ADT is intended to compete with rigid dump trucks (RDTs) in the 40t class.
The new 4×4 DA45-7 ADT complements the current market-leading range of Stage V compliant 6×6 ADTs from Doosan, which includes the DA30-7 and DA45-7 models with payloads of 28-and-41t, respectively.
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 40t class.
According to the manufacturer, the new 4×4 DA45-7 ADT has a width of less than four metres to avoid the need for special transportation and offers a better turning radius than a comparable RDT, providing particular advantages in the mining and tunnelling industries.
“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 40t class, by providing a dumper product that delivers much more than RDTs,” says Beka Nemstsveridze, ADT Product Manager at Doosan.
He concluded, “The development of our 4×4 ADT was inspired by customer demand and the new 4×4 ADT can meet the needs of markets around the world by offering a compelling advantage to customers with specific requirements. For example, a machine like this might be able to extend the season for a mine that normally has to be stopped for a certain period due to the rainy season.”
