Increased Comfort and Controllability
Already excelling in spaciousness and ergonomics, the new cab in the DX300LC-7 takes operator comfort and ease of operation to unheralded levels. The new cab offers more features as standard than other machines on the market, ensuring super controllability and high precision in all applications.
The new DX800LC-5B 80 tonne crawler excavator offers optimum value to the end-user thanks to outstanding productivity, high fuel efficiency, superior comfort for the operator, enhanced reliability, durability and maximum uptime. It is therefore designed to meet the needs of heavy duty mining and quarrying applications as well as major infrastructure construction projects.
Best-in-class Productivity
Built with high quality, proven main components and offering a very robust design, the DX800LC-5B enables customers to work in environments where avoiding downtime is critical. In fact, the use of superior components throughout, specifically customized for use in large equipment, ensures this new machine offers best-in-class power, productivity and durability.
The state-of-the-art designs and developments in the new Stage V ADTs have resulted from intensive market analysis, customer visits, interviews with operators and additional feedback gathered by the Product/R&D teams at Doosan’s ADT plant in Molde in Norway.
In 2018, the DA30 ADT was upgraded with a range of features including a new cab, a new self-levelling front suspension and a new tandem bogie system which are all incorporated in the new Stage V model. A similar process has been applied in the new 40 tonne Stage V machine, with 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 models offer many more features - one of the most eye-catching is 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.
Complementing the striking external changes on the new ADTs, are the new Scania Stage V compliant 9 and 13 l
engines that now power the machines. The new Scania engines have undergone two years of very intensive testing in exacting construction and mining environments over the last two years and have passed with flying colours. Whilst the core of the Scania engines has not changed, the main difference in the new engines from their predecessors is the improved after-treatment system.
First Time For New Doosan Wheel Loaders at Bauma
Offering a dedicated design for waste and recycling and general industrial applications, the new DL280-5 will be shown in its full waste industry configuration at Bauma. The ‘Waste Kit’ includes protectors for lifting and bucket cylinders, articulation, rims, lamps, the rear engine bonnet and the front windscreen, which is tiltable for easy cleaning. The DL280-5 is tailored for waste applications, with a wide core radiator and heavy duty axles, which are approved for the use of solid tyres. The DL280-5 offers high performance and high productivity with an outstanding breakout force, tipping load and enhanced output. The DL280-5 features Z-bar kinematics with a simple lifting piston system designed for heavy-duty applications.
With a maximum bucket capacity of 4.4 m3, the DL420CVT-5 combines the benefits of a mechanical and a hydrostatic transmission in the same machine. This allows the DL420CVT- 5 to automatically transition from hydrostatic power at low speed to the mechanical system to operate at higher speeds. The complete driving range, forwards and in reverse, is controlled by the CVT system, which can provide fuel savings of up to 25%.
The new DL580-5 has a bucket capacity of 6.4 m3 and a similar look to the next model down the range, the DL550-5, but features robust structural components and an advanced sophisticated double circuit axle cooling system to provide an ideal solution for applications such as block lifting and other heavier material-handling needs. 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.
