The 22-ton EC220E crawler excavator has a 172-horsepower, Tier 4-Final Volvo D6 engine that delivers 5 percent better fuel efficiency compared with the C Series predecessor, Volvo says. Paired with a hydraulics system that has increased pump input power, the excavator matches power requirements to the task. With the boom float function, pump power normally used for boom lowering can be saved or used for other functions. A new valve proportionally controls the boom operation according to the arm operation while grading, and also improves lifting controllability while traveling simultaneously.
The operator can adjust joysticks, keypad and 8-inch LCD monitor. The number of switches has been reduced, and the climate control has been integrated into the keypad. An optional sideview camera in addition to the rearview camera covers the visual blind spots. Both views are displayed on the color monitor.
The X-shape lower frame enables even weight distribution for increased stability and durability and helps prevent damage from rocks and debris. The heavy-duty undercarriage likewise creates excellent tractive force in demanding terrain. The robust design of the boom and arm includes internal plates positioned to support pressure points during a wide range of applications. These plates help disperse pressure to ensure maximum productivity and uptime from the excavator, Volvo says.
Grouped filters are easily accessible from ground level, and the single-layer cooling system can also be accessed from ground level. The radiator charged air cooler and hydraulic oil cooler are situated side-by-side to maximize efficiency, reduce blockages and aid cleaning. Should a technician or operator need to access the superstructure for inspection or maintenance, full size guard rails help maintain three-point contact at all times, while well-positioned, punched and removable anti-slip plates offer good grip.
