Doosan expanded its Tier 4 excavator lineup with two new wheeled models – the DX140W-5 and the DX190W-5 – for applications that require an excavator with rubber tires. These excavators replace Doosan’s Tier 4 Interim 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. According to Doosan, the 132-net-hp DX140W-5 and 168-net-hp DX190W-5 wheel excavators offer a new selectable feature, SPC engine mode, which comes as standard. 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 SPC is engaged. Each of the four power modes will function with SPC engaged or disengaged, but SPC can be active only in the digging work mode.
