Conexpo-Con/Agg 2020: New Doosan machines powered by innovation

Doosan DL580-5 wheel loader

New DA45 articulated dumptruck and DL580-5 wheel loader to make their show debut

ATTENDEES at this year’s Conexpo-Con/Agg 2020 Exhibition from 10-14 March 2020 in Las Vegas in Nevada in the USA, will be able to see new equipment powered by innovation from Doosan Infracore North America, LLC.

Visitors will be able to 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 as the company invests in meeting the construction industry’s future equipment and technology needs.

The new Stage V compliant DA45 ADT, which is being shown for the first time at Conexpo-Con/Agg 2020, has a payload of 41 tonnes and is powered by the new Scania Stage V DC13 13-litre diesel engine with its improved after-treatment system and an output of 368kW (500hp).

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 many more features – including a new eye-catching is design for the front frame and bonnet components, in accordance with the latest trends in the market.

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 guarantees permanent six-wheel contact and drive for equal power distribution and excellent 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.

With a bucket capacity of 5.4 cubic metres, 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 sophisticated double-circuit axle oil cooler system. This provides an optimum 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 36,030kg and higher static tipping loads (straight/full turn 40° degrees) of 29,700kg and 26,200kg, respectively. The overall size of the DL580-5 is almost the same as the DL550-5, but Doosan say the new model is equipped with a series of features that make the machine extremely 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 stabilize the loader, allows 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 allowing higher dumping of materials.

The DL580-5 is powered by the Scania DC13 6-cylinder engine producing 283kW (380hp) of power at 1,800 rev/min. The Scania DC13 engine provides a maximum torque of 1,765Nm at 1,300 rev/min and up to a 10% reduction in fuel consumption and excellent response. 

As well as the powerful Scania DC13 engine, the DL580-5 also features automatic five-speed powershift transmission, heavy-duty cooled axles, a high-comfort cab, smooth and responsive hydraulics and auxiliary hydraulic connections. As with all other Doosan DL-5 wheel loaders, most of these features are standard on the DL580-5 and many have been developed to optimize fuel efficiency.

Meanwhile, fleet managers can improve maintenance and enhance productivity with data from Doosan’s online telematics offering, the DoosanCONNECT system. Using built-in monitoring hardware on Doosan machines, DoosanCONNECT provides real-time diagnostics, critical alerts and shareable data, empowering fleet managers and equipment owners to reduce downtime and maximize equipment investments.
