New Doosan machines to be showcased at CONEXPO-CON/AGG 2020

Published by , Deputy Editor
World Cement,

Attendees at this year’s CONEXPO-CON/AGG 2020 Exhibition from 10 –14 March 2020 in Las Vegas in Nevada, US, will be able to see new equipment from Doosan Infracore North America, LLC. A line-up of excavators, wheel loaders and articulated dump trucks (ADTs) will be presented at Doosan’s stand, N10001, at the show.

Visitors can explore the latest Doosan® models such as the DA45 ADT, the DL580-5 wheel loader and the DX800LC-5 crawler excavator – the largest Doosan machine yet. Doosan will also showcase Concept-X, an autonomous worksite in development.

The new Stage V compliant DA45 ADT is being shown for the first time at CONEXPO-CON/AGG 2020. The DA45 has a payload of 41 t and is powered by the new Scania Stage V DC13 13 litre diesel engine with an output of 368 kW (500 HP).

The new Scania engine has undergone two years of very intensive testing in exacting construction and mining environments and have passed. Whilst the core of the Scania engine, which has been responsible for its reliability, has not changed, the main difference in the new engine from its predecessor is the improved after-treatment system.

New features

The new DA45 Stage V machine features a new cab and a semi-levelling front suspension that adjusts itself independently depending on the operating conditions to ensure a comfortable working environment for the operator. As well as these changes, the new Stage V model offers a new design for the front frame and bonnet components on the trucks, created by the Doosan design team in accordance with the latest trends in the market.

Rough and soft terrain performance

Like all Doosan ADTs, the new DA45 features 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 permanent 6-wheel contact and drive for equal power distribution and sound 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.

Ideal for heavier materials handling

With a bucket capacity of 5.4 m3, the DL580-5 top-of-the-range wheel loader has a similar look to the next model in the range, the DL550-5, but features robust structural components and an advanced double circuit axle oil cooler system. This provides an ideal solution for applications such as block lifting and other heavier material-handling needs in industrial, construction, recycling, mining and quarrying applications.

To meet these requirements, the DL580-5 has an operating weight of 36030 kg and higher static tipping loads (straight/full turn 40°) of 29700 and 26200 kg, respectively. The overall size of the DL580-5 is almost the same as the DL550-5, but the new model is equipped with a series of features said to make the machine more reliable and durable.

For example, the front structure is more rugged, with greater rigidity and strength. The DL580-5 has reinforced Z-bar kinematics for heavier lifting with few moving parts. This design also helps stabilise the loader, enables rapid bucket movements and keeps the bucket at the right angle position at all times. As with all Doosan DL-5 models, the DL580-5 is also available with a high-lift configuration, with a longer arm enabling higher dumping of materials.

The DL580-5 is powered by the Scania DC13 6-cylinder engine producing 283 kW (380 HP) of power at 1800 rpm. The Scania DC13 engine provides a generous maximum torque of 1765 Nm at 1300 rpm and up to a 10% reduction in fuel consumption.

As well as the Scania DC13 engine, the DL580-5 also features automatic 5-speed powershift transmission, heavy duty cooled axles, a high comfort cab, smooth and responsive hydraulics and auxiliary hydraulic connections, together providing a solution for the heaviest jobs that need to be done. As with all other Doosan DL-5 wheel loaders, most of these features are standard on the DL580-5.

DoosanCONNECT telematics system
