Doosan DA40-5


Ideal for construction sites as well as mining and quarrying applications, the Doosan® DA40-5 offers excellent driving stability, equal weight distribution and superior traction along with additional load capacity, superior power and better productivity.

Its flexible and agile undercarriage ensures all six wheels have permanent ground contact, so you can achieve extreme performance in off-road conditions. And, with a high horsepower per ton of loaded weight ratio and a diesel engine that provides a class-leading power-to-weight ratio, you'll maintain your momentum and increase productivity.

Two lateral limited-slip differentials, one front & one rear, deliver top traction, while a free-swinging rear tandem gear-driven bogie delivers added stability. A single driveline uses one longitudinal differential delivering a 50 percent split between the front and rear drivetrains.

A strong frame and body design with lightweight, high-grade, wear-resistant steel reduces the total weight of the truck, which requires less horsepower for operation. A sloping rear frame, combined with an ideal track width provides a low center of gravity. A gradient meter helps you monitor the incline and pitch of loads for improved safety.

Inside the cab, you’ll find comfort everywhere you look. An air suspension seat, fully automatic climate control, and a rubber suspension cab mounting provide excellent comfort all day long. Controls are placed at your fingertips for easy operation, while a multi-function monitor displays critical machine information on an easy-to-read 7 in. screen. Further monitor your Doosan equipment and manage maintenance to reduce operating costs with Doosan Connect Telematics.

To reach Tier emissions standards, the DA40-5 incorporates a high-pressure common-rail (HPCR) fuel delivery system as well as cooled exhaust gas recirculation (CEGR) combined with a diesel oxidation catalyst (DOC) and selective catalyst reduction (SCR).
