Volvo Construction Equipment says its new D-Series excavators — the EC140D, EC160D, and EC220D — feature the latest fuel-efficient Tier 4 Interim-compliant Volvo engines and enhanced hydraulics, which means greater digging forces, faster cycle times, and better fuel efficiency. Each track is powered by an automatic two-speed shift travel motor and features greased and sealed track chains. The superstructure features anti-slip plates, steps, and handrails for safe access. A rear access behind the cab of the EC140D and EC160D models brings the main hydraulic components and engine within easy reach. Maximum net power ranges from 113 horsepower for the EC140D to 172 horsepower for the EC220D.
