Doosan introduces two new excavators

Doosan, headquartered in West Fargo, North Dakota, has expanded its Tier 4 excavator lineup with two new wheel models—the DX140W-5 and DX190W-5. The new “dash-5” excavators, which have rubber tires, target applications that require an excavator with rubber tires.

The new excavators replace the “dash-3” (interim Tier 4) models. In addition to a Tier 4 diesel engine, the new models feature improved fuel efficiency from a new smart power control (SPC) selectable engine mode and multiple product enhancements.

Doosan says the 132-net-horsepower DX140W-5 and 168-net-horsepower DX190W-5 wheel excavators are ideal for customers who regularly drive on finished concrete or asphalt surfaces.

A new selectable feature, SPC engine mode, is standard on both excavators. SPC consists of two systems—variable speed control and pump torque control—that work together to improve machine efficiency, while maintaining productivity and reducing fuel consumption. The engine control unit automatically manages SPC when it is engaged. Each of the four power modes will function with SPC engaged or disengaged; however, SPC can be active only in the digging work mode, Doosan clarifies.

Doosan says its DX140W-5 and DX190W-5 excavators offer customers multiple product enhancements without changing any of the performance, comfort and ease of service features of the dash-3 predecessors.

The company points out these features of the machines: 

 

The Doosan DX140W-5 and DX190W-5 wheel excavators comply with Tier 4 emission standards. Both models are fitted with Doosan DL06 diesel engines and after-treatment technologies, and do not require a diesel particulate filter (DPF). The engines are optimized for use with a high-pressure common-rail fuel delivery system and a cooled exhaust gas recirculation (CEGR) system. They use a diesel oxidation catalyst (DOC) to reduce particulate matter and selective catalyst reduction (SCR) after treatment to reduce nitrogen oxides. Additionally, a variety of after-treatment systems have been implemented as part of the Tier 4 compliance, such as diesel exhaust fluid, which is used with SCR technology.

Doosan excavators come with a standard three-year subscription to Doosan Telematics, which allows equipment owners and fleet managers to remotely monitor machine location, hours, fuel usage, engine idle versus work time and error codes, as well as engine and hydraulic temperatures. Machines can be monitored via an online Doosan Telematics account. In addition, Doosan says that its dealers can provide improved customer support using the system by responding to machine warning messages and alerts, troubleshooting machine issues, and then sending a field service vehicle to help with repairs and deliver the proper parts.
