Doosan held a media event Oct. 10-12, in Tucson, Ariz., that included hands-on operation of heavy equipment, and the introduction of its new DA40 Articulated Dump Truck. Rock Products’ Assistant Editor Josephine Smith attended the event.
The two-day Doosan Editor Boot Camp took place at the company’s Real Operation Center (ROC) located at the Asarco Mission Mine. While at the ROC, members of the media were able to operate excavators, such as the new 70-ton DX700LC, and wheel loaders, such as the new DL220. The DX700LC is Doosan’s largest crawler excavator designed for the most demanding applications and large construction projects. When equipped with a 9-ft. by 6-in. arm, the excavator has a dig depth of 25 ft. 5 in., a maximum reach of 41 ft. 8 in., and a dump height of 26 ft. 10 in.
The DA40 that was on display at the ROC was being used for testing, and was not operated. However, an in-depth presentation of the new ADT was provided by a Doosan product specialist. The DA40 is the first in a new family of Doosan ADTs offering increased engine power and torque, higher payloads, lower fuel consumption, enhance operator comfort and faster travel speeds.
Some of the DA40’s features include auto lube, permanent six-wheel drive, and a powerful engine brake and hydraulic transmission retarder. In addition, 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, according to the company.
The Doosan DA40 articulated dump truck is now in production.
