New ADTs offer the lowest cost-per-ton transported

Winter 2015

 

Two new Doosan articulated dump trucks (ADTs) utilize Tier 4 compliant engines and feature superior performance, improved fuel efficiency, and increased reliability, serviceability and operator comfort. The 365-horsepower DA30-5 and 490-horsepower DA40-5 are designed to deliver one of the lowest costs of ownership available in the market today.

Improved fuel efficiency in new Doosan ADTs is achieved with engines that provide more torque with the lowest rpms, an 8-speed countershaft transmission and one rear differential — for reduced power loss as well as increased component durability.

Driveline improvements

New driveline gear ratios provide reduced axle speed, improved component life, reduced vibration and lowered fuel consumption. A front-mounted turning ring, a sloping rear frame, tandem rear bogey and independent front suspension are all features that ensure maximum ground contact and the best transfer of power to all wheels. Doosan ADTs are ideal for mining and aggregate applications, commercial and residential site developments and infrastructure projects, based on their agility on rough as well as soft terrain.

Best-in-class operator comfort

Doosan ADT cabs are spacious and offer the lowest noise level in their class. Ergonomic, easy-to-use controls allow for increased operator efficiency and productivity. Two levers control the transmission gear selection and dumping of the box. Plus, the cushioned dumping cylinders slow the dumping and lowering speeds to reduce vibration and shock in the operator’s suspension seat. With excellent all-around visibility, with a sloping hood, Doosan ADTs offer an excellent front view and superior side view with lateral sight lines.

A 7-inch color LCD shows engine rpm, travel speed, differential locks, fuel consumption and many other machine parameters. The DA30-5 and DA40-5 come standard with a gradient meter. Two meter readings are visible on the LCD screen. Up/downhill is shown as a percentage, and sideways tilt is shown as a degree value.

Cooling updates

Included in the DA30-5 and DA40-5 ADTs is an external engine intake air grille located on the right-hand side of the truck hood. This provides cooler air to the engine intake improving engine efficiency. Also included in the new models is an air vent to help prevent over-pressurization in the engine compartment.

Tier 4 solution

The new articulated dump trucks are powered by Tier 4-compliant Scania diesel engines and have been optimized for use with a high-pressure common-rail fuel delivery system, cooled exhaust gas recirculation and variable geometry turbocharger (VGT). A selective catalyst reduction with diesel exhaust fluid and a diesel oxidation catalyst are included. Other new features include an exhaust brake and a mass airflow sensor that allows the electronic control unit to improve the management of airflow from the VGT, and optimizes fuel delivery to the combustion chamber based on engine air intake volume and rpm.
