Doosan to launch new articulated dump truck at Bauma 2022

The new 4×4 DA45-7 ADT is intended to compete with rigid dump trucks (RDTs) in the 40t class

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 March 2022, Doosan Heavy Industries and Construction broke ground on a 400,000sqm forging and casting facility in Saudi Arabia.

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.

In June 2022, Hyundai expanded its heavy construction range with two articulated dump trucks.

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.”

In August 2022, Doosan Enerbility said it won an EPC contract for the $640mn Shuaibah 3 IWP in Saudi Arabia.
