Doosan DA40 articulated dump truck

The new DA40: Power, performance, productivity and fuel efficiency

Powered by a 6-cylinder interim Tier 4 compliant diesel engine with a gross power output of 500 horsepower at 2100 rpm, the DA40 offers a 10-percent increase in engine power and a 22-percent increase in gross torque to 1750 lb ft at 1300 rpm compared with the previous MT41 model

Contributing to the overall 8-percent reduction in fuel consumption* is the new transmission offering 8 forward and 4 reverse speeds. The new transmission improves the transfer of power from the engine to the wheels for outstanding traction. To withstand the increased power, the driveline dimensions and cooling capacity of the truck have been increased.

The DA40 combines "best-in-class" fuel consumption with a higher top speed of 36 mph. The DA40 also has an increased body capacity of 31.9 cubic yards, and the payload has been boosted to 40 metric tons without tailgate, an increase of more than 15 percent over the payload of the MT41.

Six-wheel traction and outstanding rough and soft terrain capabilities

The DA40 has permanent 6-wheel drive for equal power distribution while the free-swinging rear tandem bogie and the special articulation system offer excellent driving performance in difficult terrain. The sloping body design enhances the stability of the truck thanks to its low center of gravity and allows fast and easy tipping, even in the most demanding conditions. The combination of the unique tandem bogie and the sloping rear frame results in "best in class" rough and soft terrain capabilities and avoids the need for aids such as traction control.

To handle the increased payload as well as provide a smoother ride for the operator, the DA40 has a completely new hydro-gas front suspension. This independent front suspension is a unique feature of the Doosan ADT which allows for free movement on one side, without movement on the opposite side, providing maximum ground contact and shock absorption.

The articulation hinge is positioned behind the turning ring to provide equal weight distribution even during maximum turning and ensure maximum contact between the front wheels and the ground for optimum traction.

Like all Doosan ADTs, the DA40 features a powerful engine brake and hydraulic transmission retarder as standard. The wet brakes offer a long service life and sealed protection from the environment and, with oil-cooled multiple disc brakes on all the wheels, the safety of the operator is never compromised.

Operator comfort and convenience

The DA40 has a completely new cab providing more space and improved visibility for the operator, "best in class" noise levels and a fully automatic climate control system. For easier operation, Doosan has introduced new electronic systems and simplified fingertip controls with a digital display of all desired machine functions. The fully automatic 8 gear transmission and smooth Tiptronic™ gear-shifting (both automatic and manual gear functions are available) allow the operator to concentrate on working conditions.

For routine maintenance and service, the cab can be tilted backward to provide easy access to components. Easier service access and longer service intervals result in lower operating costs. A fully automatic central greasing system and rear view camera are standard.

Doosan Introduces Two New Tier 4-Compliant Wheel Excavators with Improved Fuel Efficiency

Doosan expands its Tier 4 excavator lineup with two new wheel models — the DX140W-5 and DX190W-5 — for applications that require an excavator with rubber tires. The “dash-5” excavators replace the “dash-3” (interim Tier 4) models. In addition to a Tier 4 diesel engine, these models feature improved fuel efficiency from a new Smart Power Control (SPC) selectable engine mode and multiple product enhancements.

The 132-net-horsepower DX140W-5 and 168-net-horsepower DX190W-5 wheel excavators stand out from other excavating equipment with their rubber tires, making them a popular choice for customers who regularly drive on finished concrete or asphalt surfaces. Doosan wheel excavators are often used in highway / street development, building, manufacturing operations, site development and land improvement. For example, a wheel excavator customer can drive on the shoulder of a road to dig in an adjacent ditch or use a bucket and clamp to pick up materials and load them into a truck for disposal.

John Deere Extends Generator Drive Options With New Engine Lineup

John Deere Power Systems will extend its generator drive power solutions with the introduction of four new PowerTech prime power generator drive engines at INTERMAT, April 20 – 25 in Paris. The new engines meet U.S. Environmental Protection Agency (EPA) Final Tier 4 emissions regulations without the need for a diesel particulate filter (DPF) — giving OEMs with space-constrained installations more options for their prime power generator set applications. The engines utilize a John Deere Integrated Emissions Control system equipped with cooled exhaust gas recirculation (CEGR), a diesel oxidation catalyst (DOC), and a selective catalytic reduction (SRC) system, and join the existing lineup of Final Tier 4 generator drive engines that use the same technologies plus a DPF.

“We’ve been able to develop constant speed engines that do not require a diesel particulate filter (DPF) to meet both stringent emissions regulations and the performance our customers have come to expect,” said Darrin Treptow, manager, worldwide marketing for John Deere Power Systems.
