EC250E crawler excavators from Volvo Construction Equipment have efficient Tier 4 Final/Stage IV-compliant Volvo engines, and 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 also has the ability to manually control flow to the hydraulics using the integrated work mode system. To reduce idle time, they can be equipped with 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. 717/532-9181; www.volvoce.com.
