The EC250E crawler excavator from Volvo Construction Equipment delivers a 5 percent improvement in fuel efficiency over past models. This efficiency is not only due to the Tier 4 Final/Stage IV-compliant engine, but also a range of features that optimize flow and minimize pressure losses in the hydraulic system. The ECO mode automatically reduces fuel consumption without any loss of performance in most operating conditions. The operator has the ability to manually control flow to the hydraulics using the integrated work mode system. To reduce idle time, the unit can be equipped with optional automatic idling and auto engine shutdown systems. When a machine’s controls are inactive for a preset amount of time (between three and 20 seconds), engine speed is reduced to idle. When a machine has been motionless for five minutes, the engine automatically turns off. 828/650-2000; www.volvo.com/constructionequipment.
